Connection between the shift
cable and transmission or
body is worn
ATF pump worn or binding
Regulator valve stuck or
spring worn
ATF strainer clogged
Mainshaft worn or damaged
Final gears worn or damaged
Transmission-to-engine
assembly error
Axle disengaged Check the ATF level, and check the ATF cooler lines
for leaks and loose connections. If necessary, clean
the ATF cooler lines.
Check for a loose shift cable at the shift lever and
the selector control lever.
Improper alignment of ATF pump and torque
converter housing may cause ATF pump seizure.
The symptoms are mostly an rpm-related ticking
noise or a high pitched squeak.
Check the line pressure.
Be careful not to damage the torque converter
housing when replacing the main ball bearing. You
may also damage the ATF pump when you torque
down the main valve body. This will result in ATF
pump seizure if not detected. Use the proper tools.
Install the main seal flush with the torque converter
housing. If you push it into the torque converter
housing until it bottoms out, it will block the fluid
return passage and result in damage.
Check the ATF strainer for debris. If the ATF
strainer is clogged with particles of steel or
aluminum, inspect the ATF pump. If the ATF pump
is OK, find the damaged components that caused
the debris. If no cause for contamination is found,
replace the torque converter.
Inspect the differential pinion gears for wear. If the
differential pinion gears are worn, replace the
differential assembly, replace the ATF strainer,
thoroughly clean the transmission, and clean the
torque converter, cooler, and lines.
Vehicle moves in R,
but not in D, S, or
1st in S 1.

3.1st accumulator defective
1st gears worn or damaged
1st clutch defective Check the 1st clutch pressure.
Inspect the clutch piston, the clutch piston check
valve, and the O-rings. Check the spring retainer
and the retainer seal for wear and damage. Inspect
the clearance between the clutch end-plate and the
top disc. If the clearance is out of tolerance, inspect
the clutch discs and the plates for wear and
damage. If the discs are worn or damaged, replace
them as a set. Inspect the clutch wave-plate height.
If the height is out of tolerance, replace the wave-
plate. If the discs and the plates are OK, adjust the
clearance with the clutch end-plate.
Inspect the 1st clutch feed pipe. If the 1st clutch
feed pipe is scored, replace the end cover.
Replace the secondary shaft if the bushing for the
1st clutch feed pipe is loose or damaged.
Check the 1st accumulator piston, the O-ring, and
the springs in the regulator valve body for wear
and damage.

The five-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission
gears. When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction
discs and the steel plates together, locking them so they do not slip. Power is then transmitted through the engaged
clutch pack to its hub-mounted gear. Likewise, when the hydraulic pressure is bled from the clutch pack, the piston
releases the friction discs and the steel plates, and they are free to slide past each other. This allows the gear to spin
independently on its shaft, transmitting no power.

33. Attach the front subframe adapter (VSB02C000016)
to the front subframe by looping the strap (A) over
the front of the front subframe, then secure the
strap with the stop (B), then tighten the wing nut (C).
34. Raise a jack and line up the slots in the arms with the bolt holes on the corner of the jack base, then
tighten the bolts.
35. Remove the four bolts securing the front subframe, and lower the front subframe.
36. Secure the steering gearbox to the body with a rope. 37. Remove the driveshafts from the differential and
the intermediate shaft. Coat all precision machined
surfaces with clean engine oil, then put plastic bags
over the driveshaft ends.
38. Remove the three bolts securing the shift cable holder (A), then remove the shift cable cover (B).
39. Pry up the lock tab of the lock washer (C), and remove the lock bolt (D) and the lock washer, then

1. Install both axles into the differential, and place the
axles on V-blocks (A).
2. Measure the backlash of the pinion gears (B) using a dial indicator (C).
3. If the backlash is out of standard, replace the differential carrier. NOTE: Inspect and adjust the carrier bearing preload
(see page 14-361) whenever the differential carrier is
replaced.
1. Remove the final driven gear (A) from the differential carrier (B).
NOTE: The final driven gear bolts have left-hand
threads.
2. Install the final driven gear on the differential carrier in the direction shown. Tighten the bolts to
103 N·m (10.5 kgf·m, 75.9 lbf·ft) in a crisscross
