TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
²Torque converter weld leaks at the outside diam-
eter weld (Fig. 8).
²Torque converter hub weld (Fig. 8).
REMOVAL
NOTE: If transaxle assembly is being replaced or
overhauled (clutch and/or seal replacement), it is
necessary to perform the TCM Quick Learn Proce-
dure. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/TRANSMISSION CONTROL
MODULE - STANDARD PROCEDURE)
(1) Disconnect battery cables.
(2) Remove battery shield (Fig. 9).
(3) Remove coolant recovery bottle (Fig. 10).
(4) Remove fluid level indicator/tube assembly.
Plug opening to prevent debris from entering trans-
axle.
(5) Using a blade or suitable hose cutter, cut trans-
axle oil cooler lines off flush with fittings. Plug lines
and fittings to prevent debris from entering transaxle
or cooler circuit. A service splice kit will be installed
upon reassembly.
(6) Disconnect input and output shaft speed sensor
connectors (Fig. 11).
(7) Disconnect transmission range sensor (TRS)
connector (Fig. 11).

(14) Remove low/reverse accumulator (Fig. 28).
(15) Measure input shaft end play. Place transaxle
so input shaft is vertical. Set up end play set and
dial indicator as shown in (Fig. 29).Input shaft end
play should be within 0.13-0.64 mm (0.005-0.025
in.)If outside of this range, a #4 thrust plate change
is required. Record indicator reading for reference
upon reassembly.(16) Remove oil pump-to-case bolts (Fig. 30).
CAUTION: Be sure input speed sensor is removed
before removing oil pump.

(25) Remove front carrier/rear annulus assembly
and #6 needle bearing (Fig. 40).
(26) Remove rear sun gear and #7 needle bearing
(Fig. 41).
NOTE: The number 7 needle bearing has three anti-
reversal tabs and is common with the number five
and number two position. The orientation should
allow the bearing to seat flat against the rear sun
gear (Fig. 42). A small amount of petrolatum can be
used to hold the bearing to the rear sun gear.(27) Setup tool 5058 as shown in (Fig. 43). Com-
press 2/4 clutch return spring (just enough to remove
snap ring) and remove snap ring.

over the 2/4 clutch retainer before compressing. If
necessary, fasten the 5058 bar to the bellhousing
flange with any combination of locking pliers and
bolts to center the tool properly.
