Cutlass Ciera Cruiser V6-3300 3.3L MFI VIN N (1993)
with P/N 8687998. This kit is curremly available from GMSPO. The new clutch return spring has a higher spring rate to keep the piston from partially
applying.
1993 HYDRA-MATIC 3T40 transaxles built beginning July 1, 1992 (Julian Date 182) already contain the new design return spring and spiral retaining
ring.
The new return spring and spiral retaining ring can be used to service any 1992-93 HYDRA-MATIC 3T40 (previously THM 125-C) transaxle.
Notice:
Do not install the new design return spring in 1991 or previous HYDRA-MATIC 3T40 transaxles. These models have not had their hydraulic pressures
recalibrated to accept the new spring with a higher spring rate. Transaxle damage will result if this new return spring is installed in 1991 or previous
HYDRA-MATIC 3T40 models.
If the previous design return spring and retainer is being replaced with the new design, install the lo blow off line-up from the service package into the
transaxle when the return spring is changed.
No change was made to the piston or housing.
The lo and reverse clutch spring retainer (656) was eliminated in the design change.
