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
separate the shift cable (E) from the selector control
shaft (F). Do not bend the shift cable excessively.

8. Secure the transmission mount bracket on the
transmission housing with new mounting bolts.
9. Install a new set ring (A) on the intermediate shaft (B). 10. Clean the areas where the intermediate shaft
contacts the transmission (differential) with solvent,
and dry with compressed air. Apply intermediate
shaft splines with ATF, then install the intermediate
shaft, be sure not to allow dust or other foreign
particles to enter the transmission.
11. Install the intermediate shaft cover (C) with installing the m ounting bolts loosely.
12. First tighten the right upper bolt (D) on the cover, then the right lower bolt (E), and lastly the left bolt
(F).
13. Install a new set ring (A) on the left driveshaft (B).
14. Clean the areas where the left driveshaft contacts the transmission (differential) with solvent, and dry
with compressed air. Then install the left driveshaft,
be sure not to allow dust or other foreign particles
to enter the transmission. Turn the steering knuckle
fully outward, and slide the driveshaft into the
differential until you feel its set ring fully engage
thesidegear.
15. Apply right driveshaft inboard-joint splines with the recommended grease (P/N 08734-0001).
16. Slide the right driveshaft over the intermediate shaft splines until you feel the driveshaft fully
engage the intermediate shaft set ring.
Replace.

6. Align the spring pin (A) on the selector control shaft (B) with the transmission housing groove (C) by
turning the selector control shaft with the control
lever.
NOTE: Do not squeeze the end of the selector
control shaft tips together when turning the shaft.
7. Use snap ring pliers to expand the snap ring of the secondary shaft bearing. Then lift the transmission
housing. Release the snap ring pliers and remove
the transmission housing.
8. Remove the countershaft r everse gear and the
needle bearing.
9. Remove the lock bolt securing the shift fork, then remove the shift fork with the reverse selector
together.
10. Remove the control lever from the selector control shaft.
11. Unlock the detent spring (A) from the detent arm (B). 12. Remove the selector control shaft (A) from the
torque converter housing.
13. Turn the detent arm (B) away from the countershaft (C).
14. Remove the mainshaft subassembly (A), the countershaft subassembly (B) and the secondary
shaft subassembly (C) together. Do not bump the
countershaft on the baffle plate (D).
15. Remove the baffle plate.
16. Remove the differential assembly.

NOTE: Refer to the Exploded View as needed during the
following procedure.
1. Install the differential assembly in the torque converter housing.
2. Install the baffle plate on the servo body (see step 9 on page 14-343).
3. Assemble the mainshaft, the countershaft, and the secondary shaft.
4. Join the mainshaft subassembly (A), the countershaft subassembly (B), and the secondary
shaft subassembly (C) together. Then install them
in the torque converter housing. Do not bump the
countershaft on the baffle plate (D).
5. Make sure if the countershaft and the differential are clear of the baffle plate. 6. If the detent arm was removed, install the detent
arm (A) with the arm collar (B) on the servo body
(C), and install a new lock washer (D) by aligning its
cutout (E) with the projection (F) of the servo body.

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
pattern in at least two steps.
