(16) Install manual shaft seal (Fig. 343).
INSTALLATION
NOTE: If valve body assembly is being replaced or
reconditioned, it is necessary to perform the TCM
Quick Learn Procedure. (Refer to 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/TRANSMISSION

1/8º bead of Mopar tSilicone Rubber Adhesive Seal-
ant to the oil pan and install (Fig. 347). Torque oil
pan-to-transaxle case bolts (Fig. 348) to 19 N´m (165

DISASSEMBLY
NOTE: If transaxle is being overhauled (clutch and/or
seal replacement) or replaced, it is necessary to per-
form the PCM/TCM Quick Learn Procedure. (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MODULES/POW-
ERTRAIN/TRANSMISSION CONTROL MODULE - STAN-
DARD PROCEDURE)
NOTE: This procedure does not include final drive
(differential) disassembly.
(1) Remove input and output speed sensors.
(2) Remove three (3) solenoid/pressure switch
assembly-to-case bolts. (3) Remove solenoid/pressure switch assembly and
gasket (Fig. 1).

(52)DETERMINING #4 THRUST PLATE
THICKNESS / INPUT SHAFT END PLAY: (a) Select the thinnest #4 thrust plate thickness
and install to input clutch assembly (Fig. 125). Use
petrolatum to retain. (b)
Install input clutch assembly into position and
verify that it is completely seated by viewing through
input speed sensor hole. If view through input speed
sensor hole is not as shown in (Fig. 126), the input
clutch assembly is not seated properly.
(c) Remove oil pump o-ring (Fig. 127). Be sure
to reinstall oil pump o-ring after selecting the
proper #4 thrust plate. (d) Install pump and gasket to transmission.
Install and torque bolts. (e) Set up input shaft for measurement with
Indicator Set C3339 and End Play Set 8266 as
shown in (Fig. 128). (f) Measure the input shaft end play with the
transaxle in the vertical position. Input shaft end
play must be within 0.005 to 0.025 inch. For
example, if end play reading is 0.055 inch, select
No. 4 Thrust Plate which is 0.071 to 0.074 thick.
This should provide an input shaft end play read-
ing of 0.020 inch which is within specifications. (g) Refer to the No. 4 thrust plate chart to select
the proper No. 4 thrust plate:

ACCUMULATOR
DESCRIPTION
The 4XTE underdrive, overdrive, low/reverse, and 2/4
clutch hydraulic circuits each contain an accumulator.
An accumulator typically consists of a piston, return
spring(s), and a cover or plug. The overdrive and under-
drive accumulators are located within the transaxle
case, and are retained by the valve body (Fig. 145).
The low reverse accumulator (Fig. 146) is also
located within the transaxle case, but the assembly is
retained by a cover and a snap-ring.
The 2/4 accumulator is located in the valve body. It is
retained by a cover and retaining screws (Fig. 147).
VALVE BODY
REMOVAL
NOTE: If valve body is replaced or reconditioned,
the TCM Quick Learn Procedure must be per-
formed. (Refer t o 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/TRANSMISSION CONTROL
MODULE - STANDARD PROCEDURE)
(1) Disconnect battery negative cable.
(2) Disconnect gearshift cable from manual valve
lever. (3) Remove manual valve lever from manual shaft.
(4) Raise vehicle on hoist.
(5) Remove oil pan bolts (Fig. 148).

CAUTION: The valve body manual shaft pilot may
distort and bind the manual valve if the valve body
is mishandled or dropped.
DISASSEMBLY
NOTE: If valve body assembly is being recondi-
tioned, the PCM/TCM Quick Learn Procedure must
be performed. (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL MODULES/TRANSMISSION
CONTROL MODULE - STANDARD PROCEDURE)
(1) Remove manual shaft seal (Fig. 154). (2) Remove Transmission Range Sensor retaining
screw (Fig. 155).
(3) Remove Manual Shaft/Rooster Comb and
