Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention disclosed in this application relates
generally to systems and methods for servicing automobile
transmissions, and more particularly it relates to a kit and
related methods for performing a transmission fluid flow test
and/or installing an external transmission fluid filter.
[0003] 2. Description of the Related Art
[0004] Lubrication and cooling of the working parts of the
transmission of a vehicle is usually accomplished through the use
of an oil, which is commonly known as transmission fluid.
Transmission fluid life can be dramatically extended if the
transmission fluid is kept cool and clean. Typically, vehicles are
provided with a cooling device to cool the transmission fluid as it
is cycled between the transmission and the cooling device during
operation of the vehicle. To keep the transmission fluid clean,
usually the transmission casing houses an internal fluid
filter.
[0005] However, it is known that use of an external transmission
fluid filter generally enhances the cleanliness of the transmission
fluid by extracting from it particulates that are too small to be
captured by the internal transmission fluid filter. In some cases,
continual cleaning of the transmission fluid by an external filter
may actually produce cleaner transmission fluid than new
transmission fluid put into the transmission. The external filter
may be installed somewhere in the flow circuit of the transmission
fluid, such as in the line from the cooler to the transmission.
Installation of the external filter usually requires opening the
flow circuit, which is formed by rubber or steel tubes. The
external filter is then placed in the flow circuit through the use
of hose segments, hose connector adapters, and hose clamps.
Installation of the external filter closes the flow circuit.
[0006] It is typically recommended that each time the transmission
is serviced, or the external filter is replaced, a transmission
fluid flow test be performed. A transmission fluid flow test ("flow
test") may consist, for example, of collecting transmission fluid
in a container for a predetermined period of time. For any given
vehicle make, the manufacturer provides specifications as to how
much fluid volume should be collected in a given period of time.
For example, for some vehicles adequate transmission fluid flow is
indicated if about 32-ounces of transmission fluid is collected in
about 15 seconds.
[0007] A variety of kits are known for installing an external
transmission fluid filter. Typically these kits include an external
filter, a hose segment, and related hose connector adapters and
hose clamps. However, typically these kits do not provide a
transmission fluid container ("container") for aiding in performing
the flow test. A container facilitates the collection of
transmission fluid, and it may provide a visual indication of the
adequacy of the fluid flow. Although some kits may provide a
container, these containers do not provide protection from the
potentially harmful hot transmission fluid, which may be at a
temperature as high as 120.degree. F., to the operator conducting
the flow test. Moreover, the known kits do not incorporate features
to prevent the easy removal and/or transfer of parts of the kit.
This results in the problem that an operator often encounters
incomplete or damaged kits at the time of performing a flow test or
installing the external filter.
[0008] Thus, there exists a need in the relevant technology for a
kit for installing an external transmission fluid filter that
provides protection to the operator from hot transmission fluid,
and also provides enhanced tamper resistance in order to minimize
the occurrence of incomplete or damaged kits.
SUMMARY OF THE INVENTION
[0009] The inventive kit and related methods disclosed herein has
several aspects, no single one of which is solely responsible for
its desirable attributes. Without limiting the scope of the
invention as expressed by the claims which follow, its more
prominent features will now be discussed briefly.
[0010] In one embodiment, the invention consists of a container for
collecting fluid. The container may comprise a substantially hollow
body defining an interior space for collecting a fluid therein. The
hollow body may comprise a first end, an intermediate portion, and
a second end. The container may further comprise an opening at the
first end of the hollow body for receiving the fluid therethrough,
and the opening is configured to be sufficiently large to receive
an external transmission fluid filter. The container may be further
configured with a wall at the second end of the hollow body to seal
the second end. The container may also comprise a handle integrally
attached to the hollow body. The handle may be positioned within
the periphery of the external outline of the hollow body, and may
additionally be positioned in the intermediate portion.
[0011] In another embodiment, the invention consists of a kit for
performing a transmission fluid flow test and/or installing an
external transmission fluid filter. The kit may comprise an
external transmission fluid filter for installation in the flow
circuit of a vehicle's transmission fluid cooling system, a hose
segment for coupling the filter to a line of the flow circuit; and
a plurality of hose connector adapters for coupling the hose
segment to the filter and the line of the flow circuit. The kit may
further comprise a plurality of hose clamps for securing the hose
segment to the hose connector adapters. In some embodiments, the
kit further comprises a container having an opening sufficiently
large for receiving the filter, the hose segment, the plurality of
hose connectors, and the plurality of hose clamps. The container
may further comprise a body enclosing a volume sufficiently large
for storing the filter, the hose segment, the plurality of hose
connectors, and the plurality of hose clamps. Additionally, the
volume of the container may be sufficiently large for receiving an
adequate amount of transmission fluid for performing a transmission
fluid flow test on a vehicle. The container may further comprise a
handle located within the outline of the periphery of the body, and
additionally the handle may be also located between a top end and a
bottom end of the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0034] The following detailed description is directed to certain
specific embodiments of the invention. However, the invention can
be embodied in a multitude of different ways as defined and covered
by the claims. In this description, reference is made to the
drawings wherein like parts are designated with like numerals
throughout.
[0035] FIG. 1 diagrammatically shows the components of a
transmission fluid flow test kit 10 ("kit") in accordance with one
embodiment of the invention. The kit 10 may comprise a container 12
having a handle 14 and a lid 18. The container 10 may store a
transmission fluid filter 20 ("filter"), at least one hose 22,
several hose clamps 24 or 24', various hose connectors 26 and 26',
one or more instructions sheets 28, and multiple decals 30.
[0036] The handle 14 is located inside the periphery of the
external outline of the container 12. Additionally, the container
12 and the lid 18 are configured to provide some measure of tamper
resistance to ensure that the contents of the kit are not easily
separated from the container 12. These and other features of the
container 12 and lid 18 will be described in greater detail
below.
[0037] The handle 14 is configured to provide an orifice 13 that is
adapted to fit a hand so that the container 12 is easily gripable
by an operator. As will be further described below, the orifice 13
can be of various sizes and shapes so that a hand can comfortably
grip the handle 14.
[0038] The filter 20 is typically a filter designed to remove
damaging particulates from transmission fluid. The filter 20 may be
an in-line, i.e., external, magnetic transmission fluid filter such
as that sold under the brand name MAGNEFINE.RTM..
[0039] The hose 22 is preferably made of a material designed to
withstand the corrosive effects of transmission fluid and other
oils and conditions present in the automotive environment. For
example, the hose 22 may be made of Buna-N rubber, which has a high
resistance to degradation from exposures to oils and high
temperatures. The hose 22 may be provided in a length and diameter
suitable for the application of installing an external transmission
fluid filter in a vehicle. For example, one suitable length for the
hose 22 is about 12-inches, and a suitable diameter is about
3/8-inch.
[0040] The hose clamps 24 and 24' may be any available devices for
fastening an end of a segment of hose to a hose nipple or
connector, such as hose connectors 26 and 26'. FIG. 1 shows a
worm-drive hose clamp 24 that is well known in the relevant
technology. The worm drive hose clamp 24 adjusts over a wide
diameter range and provides a uniform clamping force for a secure
seal. FIG. 1 also shows a constant-tension coolant hose clamp 24',
which is readily available commercially. The hose clamp 24' has a
wide sealing area and provides optimum clamping force on all types
of coolant hose. The hose clamp 24' is a thermoplastic clamp that
adjusts to changing thermal conditions, thereby providing a
continuing clamping force even when a clamped hose contracts in
cold temperatures. A skilled technician will realize that the
clamps 24 and 24' are merely examples of a variety of devices that
could be provided in the kit 10 for fastening the hose 22 to the
hose connector adapters 26 or 26'.
[0041] The connectors 26 and 26' are hose connector adapters of the
type well known in the relevant technology. The connectors 26 and
26' shown in FIG. 1 may be, for example, stainless steel hose
nipples designed for tight-fitting connections and leakproof
sealing. Alternatively, the connectors 26 and 26' may be hose
adapters made of a thermoplastic material having resistance to the
corrosive effects of transmission fluid and other oils. FIG. 1
shows both a male hose connector adapter 26 and a female hose
connector adapter 26'. It will be apparent to the skilled
technician that any given application may require both or either of
the adapters 26 or 26'. In one embodiment, the connectors 26 and
26' may be tubing connector adapters for a {fraction (5/16)}-inch,
or a 3/8-inch, transmission fluid line to a 3/8-inch diameter hose
22.
[0042] The instructions sheet 28 may be a piece of paper having
printed instructions and information regarding the proper use of
the kit 10. The instructions and information may be in the form of
written text or iconic illustrations, or both. The written text may
be in multiple languages for wide geographical distribution, or if
desired only in just the language of a local market. The
instructions sheet 28 may have step-by-step directions as to how to
perform a transmission fluid test and how to install the in-line
transmission fluid filter 20. Additionally, the instruction sheet
28 may have information regarding precautions to be taken in either
conducting the transmission fluid test, replacing the filter 20, or
generally servicing a vehicle's transmission.
[0043] The decals 30 may be one or more stickers to be affixed to
the vehicle for future reference as to the performance of the
transmission fluid test and installation of the filter 20.
Preferably the decals 30 are configured to allow an operator to
write information upon the decals 30. Also, preferably the decals
30 are made of a material that will stick either to the metal parts
of the vehicle (e.g., the transmission pan) or to the windows of
the vehicle, or both.
[0044] FIG. 2 shows a perspective view of the kit 10 having a
container 12 storing within the several components that may be part
of the kit 10. For illustrative purposes, the container 12 is shown
with a diagrammatic cutout 5 for allowing visualization of the
parts within. As shown in FIG. 2, the container 12 is sufficiently
large to store the filter 20, hose 22, clamps 24 and/or 24',
connectors 26 and/or 26', instructions sheet 28, and decals 30. The
container 12 is provided with a lid 18 that may be secured to the
container 12 via the fingers 34 and 32 attached respectively to the
lid 18 and the container 12. Preferably, the kit 10 is assembled
and sealed during manufacturing, i.e., before being utilized by an
operator who is to perform the transmission fluid flow test and/or
installation of the filter 20. However, in some embodiments at
least some of the components of the kit 10 may be provided along
side the container 12, i.e., not all of the components of the kit
10 need be stored in the container 12.
[0045] For illustrative purposes only, FIG. 2 shows the
instructions sheet 28 conveniently rolled up into a scroll.
However, in some embodiments the instructions sheet 28 may be
simply folded and placed along one inner wall of the container 12,
or placed atop of the other components. Similarly, FIG. 2 shows the
decals 30 conveniently rolled up into a scroll. Of course, the
decals 30 may be simply folded and accommodated in the container 12
in which ever manner is thought best with regards to
manufacturability, assembly, packaging, or usability of the kit
10.
[0046] FIGS. 3 to 6 generally show that the container 12 may be a
substantially hollow body defining an interior space 23 for
collecting a fluid therein, such as a transmission fluid. The
hollow body of container 12 may have top end 31, an intermediate
portion 11, and a bottom end 33. The top end 31 is configured with
an opening 16 for receiving the transmission fluid therethrough,
and the bottom end 33 is configured with a bottom wall 19 that
seals the bottom end 33 and, thereby, enables collection of the
fluid. In this embodiment, the perimeter of the top opening 16 is
larger than the perimeter of the bottom wall 19; however, in some
embodiments the perimeter of the top opening 16 may be smaller than
the perimeter of the bottom wall 19. In other embodiments, the
perimeter of the opening 16 may be the same as the perimeter of the
bottom wall 19. It should be apparent to those skilled in the art
that while the parameter "perimeter" has been utilized throughout
the description thus far, it is also appropriate to utilize the
parameter "diameter" in specifying the relationship between the
opening 16 and the bottom wall 19. Hence, it should be recognized
that in some containers having a circular or semi-circular
configuration, for example, the diameter of the opening 16 may be
substantially equal to or greater than the diameter of the bottom
wall 19.
[0047] The hollow body of the container 12 may be configured with
an integral handle 14 positioned within the periphery of the
external outline of the hollow body of the container 12;
additionally, the handle may be positioned in the intermediate
portion 11 of the container 12. The following discussion provides a
more detailed description of the embodiment of the container 12
shown in FIGS. 3-6.
[0048] The container 12 may have an integral handle 14 that is
formed within the periphery of the outer surface of the container
12, as shown in FIGS. 3 to 6. FIG. 3 shows a side elevational view
of the container 12. The handle 14 and the external surface 15 of
the container 12 form the orifice 13 within the periphery of the
container 12 that allows an operator to wrap his/her fingers around
handle 14. In this manner, the operator may handle the container 12
in a way that minimizes injury from hot transmission fluid that may
spill onto the outer surface of the container 12. FIG. 4 is a plan
view of the container 12. FIG. 4 shows the opening 16 of the
container 12, as well as the circumferential outline of the bottom
wall 19 of the container 12. As seen in FIG. 4, the construction of
the handle 14 and gripping orifice 13 result in a ridge-like wall
17 that protrudes into the inside volume/space 23 of the container
12.
[0049] FIG. 5 is an cross-sectional view, along the plane A-A shown
in FIG. 3, of the container 12. As seen in FIG. 5, the container 12
may be formed with a wall 21 that encloses a space 23 for receiving
items, such as the components of the kit 10 or the transmission
fluid during a flow test. The wall 21 may be thin and made of
plastic, by the well-known techniques of making containers by the
process of blow molding plastic. In some embodiments, the container
12 may be made of a material capable of withstanding high
temperatures. Such suitable materials include, but are not limited
to, high temperature thermoplastics like nylon and propylene. A
container 12 made of any such material preferably withstands a
temperature of about 70.degree. F., more preferably about
120.degree. F., and most preferably greater than 140.degree. F.
FIG. 5 also shows the cross-sectional outline of the handle 14. The
handle 14 may be solid, as shown, or may be also made of a thin
wall construction similar to the construction of wall 21.
[0050] FIG. 6 is a cross-sectional view along the plane B-B of the
container 12 of FIG. 4. As seen in FIG. 6, the wall 21 of the
container 12 encloses a space 23 for receiving items therein via
the opening 16. The wall 21 also encloses the orifice 13, outlined
by the handle 14 and the external surface 15 of the wall 21, for
allowing the fingers of an operator to pass through orifice 13 and
grasp the handle 14. In FIG. 6 the handle 14 is shown as a solid
piece; however, the handle 14 may also be configured to be of
similar construction as the wall 21. FIGS. 3, 4, and 6, also depict
one embodiment of the container 12 in which its outer shape is
generally frustoconical. The periphery of the container 12 is
generally circular, tapering from the top end 31 to the bottom end
33 of the container 12. This shape of the container 12 allows for
the convenient storing and stacking of multiple kits 10--an
advantage which would not be provided if the container 12 were
configured with a handle that protrudes significantly beyond the
periphery of the container 12.
[0051] FIG. 7 is a side elevational view of one embodiment of the
container 12. In this embodiment, the container 12 may be provided
with a lid 18 having threads 25 for screwing onto threads 27 formed
on the upper end of the container 12. In another embodiment of the
container 12, as shown in FIG. 2, the container 12 may be provided
with fingers 32 that engage fingers 34 formed in the lid 18. The
fingers 34 and 32 may run along a portion of the edge of the lid 18
and the top end 31 of the container 12, respectively. In this
embodiment, the fingers 34 and 32 are configured for a
twist-and-lock operation of the lid 18. In yet another embodiment
(see FIG. 1), the top end 31 of the container 12 may be provided
with a lip 35 for engaging a lid 18 in a snap-on operation. These
features of the container 12 and lid 18 ensure that the parts of
the kit 10 stored in the container 12 do not inadvertently fall out
of the container 12, and provide a certain measure of deterrence
against the separation of the parts of the kit 10 from the
container 12. It is preferable that the kit 10 be complete when
provided to an operator that is to perform a flow test and/or
installation of the filter 20.
[0052] To further enhance the tamper resistance of kit 10, in one
embodiment the container 12 is fitted with a seal 38 that is
affixed to the top surface 29 (see FIG. 4) of the container 12. The
seal 38 closes the opening 16 of the container 12. The seal 38 may
be made of a variety of materials, including paper, plastic,
aluminum foil, etc. The seal 38 is preferably attached to the
surface 29 with an adhesive that will allow removal of the seal 38
by hand upon pulling on an edge of the seal 38. A skilled
technician in the relevant art will appreciate that these tamper
proof features of the kit 10 advance the objective of providing a
complete kit 10 to an operator by making it less likely that
components of the kit 10 stored in the container 12 will be
separated from the container 12.
[0053] As seen in FIG. 7, the container 12 may incorporate a handle
14 that is not formed integral with the container 12. In this
embodiment the handle 14 is located within the periphery of the
outline of the container 12, but the handle 14 may be removably
attachable to the container 12. The handle 14 may be, for example,
a solid part that snaps into place in grooves 36 and 36' (not
shown) formed in the container 12.
[0054] In one embodiment, the container 12 may be made of a
translucent material and provided with markings on its surface for
indicating the amount of fluid in the container 12. These markings
"A", "B", "C", and "D" are shown in FIGS. 1, 7, and 8. However, the
markings may be text indicative of fluid volume (e.g., 8-, 16-,
24-, and 32-oz), or of fluid flow conditions (e.g., "restricted",
"adequate," or "very good"), for example. It will be apparent to
the person of ordinary skill in the relevant technology that other
indicia and/or information may be provided on the surface of the
container 12. For example, the surface of the container 12 may be
imprinted with one or more warnings as to the proper and safe use
of the kit 10, stocking part number, list of parts included in the
kit 10, etc.
[0055] As already discussed above, the shape of the container 12
may be frustoconical with a taper from the top end 31 to the bottom
end 33 (see FIG. 3). However, other shapes that incorporate a
handle 14 within the periphery of the container 12 are also
possible. For example, FIG. 8 shows a container 12' having a
generally hollow parallelepiped construction with an open face
defining a top opening 16'. In this embodiment, the peripheral
outline of a container 12' is generally rectangular, with a taper
from the top end 31' to the bottom end 33'. As is best seen in FIG.
9, which shows a cross-sectional view of the container 12' along
the plane C-C of FIG. 8, the wall 21' of the container 12' encloses
a space 23' for receiving items therein, and the wall 21' also
forms a handle 14' which forms an orifice 13' in conjunction with
the external surface 15' of the wall 21'. This embodiment of the
container 12' enables an operator to avoid contact with hot
transmission fluid that may spill onto the surface of the container
12', and it also provides for a container 12' that is easy to stack
and store.
[0056] FIGS. 10 to 12 depict one embodiment of the container 12
similar to that depicted in FIGS. 3 to 6. However, in the
embodiment of FIGS. 10 to 12, the container 12 is not configured
with the orifice 13 for allowing the fingers of the operator to
pass therethrough in order to grasp the handle 14. Rather, in this
embodiment the handle 14 is gripped between the thumb and the
forefingers of the operator. As shown in FIG. 11, which is a
cross-sectional view along the plane C-C of the container 12 of
FIG. 10, the handle 14 may be formed by a continuous contour of the
wall 21. In this case, part of the space 23 would be enclosed by
the material forming the handle 14. Alternatively, the handle 14
may be solid so as to provide enhanced protection from the hot
fluid received in the container 12, as shown in FIG. 12 which is an
alternative cross-sectional view along the plane C-C of the
container 12 of FIG. 10.
[0057] FIGS. 13-16 depict yet another embodiment of the container
12. In this embodiment, the handle 14 is located near the bottom
end of the container 12, and the orifice 13 is larger and more
rectangular--when compared with the embodiment of the container 12
shown in FIG. 3. However, the handle 14 is still integral to the
container 12 and located within the periphery of the container 12.
FIG. 14 is a plan view of the container 12 shown in FIG. 13. FIG.
15 is a cross-sectional view of the container 12 along the plane
D-D of FIG. 14. As shown in FIGS. 14 and 15 a wall 35 is formed at
the point where the handle 14 is formed onto the container 12. The
space 23 is formed by the wall 21, which includes the wall 35.
Additionally, as shown by the dashed lines in FIG. 14, the handle
14 may be configured as a strip that connects to the bottom end of
the container 12 and extends toward the edge of the periphery of
the container 12, where the strip then turns upward to the point on
the container 12 where the wall 35 begins. It will be readily
apparent that the bottom part of the handle 14, which connects to
the bottom end of the container 12, may be alternatively configured
as a thin plate with an area substantially similar to the area
defined by the bottom wall 19 forming part of the bottom end 33 of
the container 12. This configuration provides for easy stacking and
storing of the kits 10. FIG. 16 shows a side elevational view from
the left side of the container 12 shown in FIG. 13.
[0058] FIGS. 17-20 illustrate another embodiment of the container
12. This embodiment is similar to the embodiment shown in FIGS.
13-16 and described above. However, in the embodiment of FIGS.
17-20, the container 12 is configured such that the wall 21 forms
the handle 14 by thickening and widening at the location of the
handle 14. In this embodiment the lower portion 37 of the handle 14
may extend with uniform width from the edge of the periphery of the
container 12 to the point where the wall 21 defines the space 23.
Alternatively, the lower portion 37 of the handle 14 may be
configured as a semi-circular plate that in conjunction with the
bottom wall 19 of the container 12 forms a complete circular base
(not shown) for the container 12.
[0059] Both of the last two embodiments described (i.e., that of
FIGS. 13-16 and FIGS. 17-20) provide a handle 14 that substantially
isolates the hand of the operator from heat that may be transmitted
from the transmission fluid through the wall 21 of the container
12. The techniques for making any of the embodiments of the
container 12 described are well known by those skilled in the
technology of blow molding of plastics.
[0060] FIG. 21 is a schematic depiction of a transmission fluid
cooling system in which the kit 10 may be used to perform a
transmission fluid flow test and/or installation of a transmission
fluid filter 20. As shown in FIG. 21, the transmission fluid
cooling system may comprise transmission fluid lines 44 and 48. The
transmission fluid lines 44 and 48 are typically metallic tubes or
pipes, or rubber hoses, for transporting transmission fluid from a
transmission 42 to a cooling device 46 and back to the transmission
42. The kit 10 may be used to test the adequacy of the transmission
fluid flow in the circuit 50 formed by the transmission 42, line
44, cooling device 46, and line 48. Also, the kit 10 may include
all of the components necessary to install the filter 20 in the
circuit 50.
[0061] By way of example, at the time that a filter 20 is to be
installed in a vehicle having a cooling circuit 50 as substantially
depicted in FIG. 21, an operator typically cuts and removes a
segment of the line 48. The operator may then utilize a kit 10 as
described above to conduct a cooling flow test and/or install a
filter 20 in the circuit 50. Having obtained the kit 10, the
operator removes the lid 18, and if necessary the seal 38, from the
container 12. The operator may then remove from the container 12
the rest of the components of the kit 10, namely, the instructions
sheet 28, the decals 30, the hose 22, the clamps 24 and 24', and
the hose connector adapters 26 and 26'. The operator may then refer
to the instructions sheet 28 in order to know how to properly use
the kit 10.
[0062] To use the hose 22, the operator typically cuts the hose 22
into two segments 22' and 22", which will be used as described
below. The operator may then proceed to couple with a hose
connector adapter 26 or 26' one end of a hose segment 22' to the
line 48 coming from the cooling device 46, as shown in FIG. 21. The
operator then couples with a hose connector adapter 26 or 26' the
other end of the hose segment 22' to the inlet port of the filter
20. The operator then couples with the hose connector adapter 26 or
26' the outlet port of the filter 20 to one end of the hose segment
22". The operator may then utilize the container 12 to perform a
flow test.
[0063] To perform the flow test, the operator allows transmission
fluid to flow in the circuit 50, which now includes the filter 20
and is open at one end of the hose segment 22". For predetermined
period of time, the operator collects in the container 12 the
transmission fluid that flows out of the open end of hose segment
22". The appropriate predetermined period of time is typically
dictated by the vehicle manufacturer's recommendation. For example,
while performing a flow test in certain vehicles, the operator
would collect about 24 ounces of transmission fluid in about 15
seconds if the fluid flow is good.
[0064] As previously stated, the container 12 disclosed herein is
configured with an integral handle 14 located within the periphery
of the container 12. This configuration of the container 12 ensures
that the operator is protected from the hot transmission fluid
collected, which could be at a temperature from about 70.degree. to
about 120.degree. F., for example.
[0065] Although the description above refers to performing a flow
test after the filter 20 has been coupled to the line 48 (via the
hose segment 22'), it will be apparent to the person of ordinary
skill the relevant technology that the flow test may be performed
both before and/or after installation of the filter 20. Performance
of the flow test only requires that transmission fluid be collected
from the circuit 50 in the container 12 for a predetermined period
of time.
[0066] Once the flow test is completed, the operator then couples
the free end of hose segment 22" to the line 48 connected to the
transmission 42. In one embodiment, the operator enters information
onto one or more of the decals 30 and affixes the decals 30 to the
body of the transmission 42 for future reference. The information
entered onto the decals 30 may be, for example, a date on which the
flow test was performed and/or a new filter 20 was installed, fluid
flow conditions, brand of filter 20 used, next scheduled service,
etc. The container 12 may then be discarded or recycled for reuse
in manufacturing other kits 10.
[0067] While the above detailed description has shown, described,
and pointed out novel features of the invention as applied to
various embodiments, it will be understood that various omissions,
substitutions, and changes in the form and details of the device or
process illustrated may be made by those skilled in the relevant
technology without departing from the spirit of the invention. The
scope of the invention is indicated by the appended claims rather
than by the foregoing description. All changes which come within
the meaning and range of equivalency of the claims are to be
embraced within their scope.
