NOTICE: A J 28712 should be installed on any drive axle prior to service procedures on or near the drive axle. Failure to observe this can result in boot damage and possible joint failure.
^ Install the J 28712 on the differential-side joints and the wheel-side joints of both drive axles.
19. Right and left drive axle assemblies from vehicle.
20. Three bolts and rear engine torque rod from transaxle case.
21. Two bolts and flywheel cover from transaxle case housing.

29. Transaxle from engine by carefully moving transaxle away from engine toward the left side of the engine compartment and very slowly lowering the transmission jack making sure no obstructions exist.
INSPECT
^ For inspection and overhaul procedures.
NOTICE: Transaxle fluid cooler flushing must be performed when a transaxle is removed for service. The flushing procedure should be performed after the installation of the overhauled or replacement assembly. Failure to flush the system may cause damage to the system and its components.
IMPORTANT
^ Before installing the transaxle assembly, these steps and precautions must be followed:
A. Apply grease around the cup at the center of the torque converter. This will ensure ease of assembly.
B. Measure the distance (A) shown in above figure. The distance should be more than 21.4 mm (0.85-inch). If it is less than 21.4 mm (0.85-inch), the torque converter is improperly installed. Remove the torque converter and make sure to properly seat the torque converter onto the input shaft.

Refill transaxle as necessary:
A. Place vehicle on a level surface.
B. Remove fluid level indicator.
C. Add approximately 1.5 liters (1.6 qts.) of Dexron� II automatic transmission fluid GM P/N 1051855, or equivalent, into fluid filler tube.
D. Install fluid level indicator into fluid filler tube.
E. Apply parking brake and block vehicle wheels.
F. With selector lever in "P" position, start engine. DO NOT race engine.
G. Run engine at idle and move selector lever through each range and return to the "P" position.
H. With engine running at idle, remove fluid level indicator from filler tube and wipe indicator off.
I. Reinsert fluid level indicator into filler tube making sure it is seated in its original position.
J. Remove the indicator and check the fluid level. The level should be between the "FULL HOT" and "LOW HOT" marks. If the level is below the "LOW HOT" mark, add fluid to bring the level to the "FULL HOT" mark. Bringing the fluid level from the "LOW HOT" mark to the "FULL HOT" mark requires 0.3 liters (0.3 qts.) of fluid. Use Dexron� II automatic transmission fluid GM P/N 1051855, or equivalent.
