ASSEMBLY
CAUTION: The cooler bypass valve must be
replaced if transaxle failure has occurred. Do not
attempt to reuse or clean old valve.
NOTE: If transaxle is being overhauled (clutch and/or
seal replacement), the TCM/PCM Quick Learn proce-
dure must be performed. (Refer t o 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/TRANSMISSION
CONTROL MODULE - STANDARD PROCEDURE)

MENT: (a) With output gear Installd, install a 4.50 mm
(0.177 in.) gauging shim (Fig. 101) on the rear car-
rier assembly hub, using grease to hold the shim in
place. (b) Using Tool 6259, install output gear and
bearing assembly. Torque to 271 N´m (200 ft. lbs.). (c) Measure bearing end play. Attach Tool L-4432
to the gear (Fig. 100). (d) Push and pull the gear while rotating back
and forth to ensure seating of bearing rollers. (e) Using a dial indicator mounted to the trans-
axle case, measure output gear end play as shown
in (Fig. 100). (f) Refer to the output gear bearing shim chart
for the required shim to obtain proper bearing set-
ting. (g) Use Tool 6259 to remove the output gear
retaining bolt and washer. To remove the output
gear, use Tool L4407A. (h) Remove the gauging shim and install the
proper shim determined by the chart. Use grease
to hold the shim in place.

(15) Install the output gear and bearing assembly
using Tool 6261 (Fig. 102).
(16) Install NEW output gear retaining bolt and
washer (Fig. 103). Using Tool 6259, torque output
gear retaining bolt to 271 N´m (200 ft. lbs.) (Fig.
104). (17) Using an inch pound torque wrench (Fig.
105), check output shaft turning torque. Output
shaft turning torque should be within 3-8 in.
lbs. If the turning torque is too high, install a 0.04
mm (0.0016 in.) thicker shim. If the turning torque is
too low, install a 0.04 mm (0.0016 in.) thinner shim.
Repeat until the proper turning torque of 3-8 in. lbs.
is obtained.
