GROUP/SEQ. NO.: Transaxle-01
CORPORATION NO.: 687101
SUBJECT:
Vehicle Creeps Forward in Neutral and Binds in Reverse, and/or Clicks or Whines in All Forward Gears after Transaxle Servicing (Replace Damaged or Misaligned Transaxle 1st Gear Thrust Washer)
MODELS AFFECTED:
1991 - 1996 Saturns equipped with MP6 or MP7 automatic transaxles.
CONDITION:
After servicing an automatic transaxle in which the 1st clutch housing assembly has been removed, a condition may be observed in which the vehicle creeps forward in neutral and binds in reverse. The transaxle may also click or whine in all forward gears with the clicking and whining increasing in frequency with vehicle speed. The noise will be present during acceleration, deceleration and coast conditions.
CAUSE:
These conditions may be caused by the 1st gear thrust washer tangs (P/N 21001619) not being properly aligned with the slots in the 1st clutch housing assembly. A damaged or misaligned 1st gear thrust washer will affect input shaft clearances and lead to the condition(s) mentioned in this bulletin.
CORRECTION:
Inspect the 1st drive gear assembly for a damaged or misaligned 1st gear thrust washer. (Inspect for damage to 1st gear thrust bearings and 1st clutch return spring retainer.) If damage exists, the damaged component(s) will need to be replaced. To insure proper assembly of the 1st gear thrust washer in the 1st drive gear assembly, follow the procedure in this bulletin.

The following procedure will be included in the second edition, "1996 Automatic Transaxle Service Manual."
