Re: fuel filter/trans filter

the fuel filter is a maintence free part, and it is very simple to change the filter in the tranny

from the FSM
Fuel Filters
Two fuel filters are used. One is located at the bottom of the fuel pump module. The other is located inside the
module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters are designed for extended service. They do not require normal scheduled maintenance. Filters
should only be replaced if a diagnostic procedure indicates to do so.

Re: fuel filter/trans filter

for the transmission................

FLUID AND FILTER REPLACEMENT
For proper service intervals (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIPTION).
REMOVAL
1. Hoist and support vehicle on safety stands.
2. Place a large diameter shallow drain pan beneath the transmission pan.
3. Remove bolts holding front and sides of pan to transmission.
4. Loosen bolts holding rear of pan to transmission.
WK
AUTOMATIC TRANSMISSION - 545RFE - SERVICE INFORMATION 21 - 377

5. Slowly separate front of pan away from transmission allowing the fluid to drain into drain pan.
6. Hold up pan and remove remaining bolts holding pan to transmission.
7. While holding pan level, lower pan away from transmission.
8. Pour remaining fluid in pan into drain pan.
9. Remove the screw holding the primary oil filter (1)
to valve body.
10. Separate filter from valve body and oil pump and
pour fluid in filter into drain pan.
11. Inspect the oil filter seal in the bottom of the oil
pump. If the seal is not installed completely in the
oil pump, or is otherwise damaged, then remove
and discard the oil filter seal from the bottom of
the oil pump. If the seal is installed correctly and
is in good condition, it can be reused.
12. If replacing the cooler return filter (2), use Oil Filter
Wrench 8321 to remove the filter from the
transmission.
13. Dispose of used trans fluid and filter(s) properly.



INSTALLATION
CAUTION: The primary oil filter seal MUST be fully
installed flush against the oil pump body. DO NOT
install the seal onto the filter neck and attempt to
install the filter and seal as an assembly. Damage
to the transmission will result.
1. If necessary, install a new primary oil filter seal in
the oil pump inlet bore. Seat the seal in the bore
with a suitable tool (appropriately sized drift or
socket, the butt end of a hammer, or other suitable
tool).
2. Place replacement filter in position on valve body
and into the oil pump.
3. Install screw to hold the primary oil filter (1) to
valve body. Tighten screw to 4.5 Nm (40 in. lbs.)
torque.
4. Install new cooler return filter (2) onto the transmission, if necessary. Torque the filter to 14.12 Nm (125 in.lbs.).
5. Place bead of Mopar
T RTV sealant onto the transmission case sealing surface.
6. Place pan in position on transmission.
7. Install bolts to hold pan to transmission. Tighten bolts to 11.8 Nm (105 in. lbs.) torque.

21 - 378 AUTOMATIC TRANSMISSION - 545RFE - SERVICE INFORMATION
WK

8. Lower vehicle and fill transmission with Mopar
T ATF +4.

TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
T ATF +4 to transmission:
a. If only fluid and filter were changed, add
10 pints (5 quarts) of ATF +4 to transmission.
b. If transmission was completely overhauled and the torque converter was replaced or drained, add
24 pints
(12 quarts)
of ATF +4 to transmission.
3. Check the transmission fluid (Refer to 21 - TRANSMISSION/AUTOMATIC - RFE/FLUID - STANDARD PROCEDURE)

and adjust as required.

Re: fuel filter/trans filter

If you're doing the tranny service you can put in a "shift kit" while you're in there.

I installed one in mine and it's AMAZING!! Not hard to do, I have yet to make a how-to for it though. It firms up your shifts and will increase your tranny life; since it makes the clutch not slip as much as it does from the factory.
