Cutlass Ciera Cruiser V6-3300 3.3L MFI VIN N (1993)
CONDITION:
Some vehicles equipped with a 1991-93 HYDRA-MATIC 4T60-E (RPO M13) transaxle built on or before Julian Date 302 (October 28, 1992) may
exhibit a fluid leak between the helix converter seal and its bore. Under some conditions the helix converter seal may walk-out partially or completely.
Hot weather and/or extreme operating conditions are contributing factors to this concern.
CAUSE:
The above condition may be due to the taper of the helix converter seal bore and cannot be repaired at a dealership level.
CORRECTION:
Begin with the "Fluid Leak Diagnosis?" ("Automatic Transaxle On-Vehicle Service Section of the applicable 1991-93 Service Manual") which provides
a detailed procedure in locating and repairing vehicle leaks.
If it is determined the leak is from the helix converter seal, remove the transaxle assembly and replace it with a SRTA (Service Replacement
Transmission Assembly).
SERVICE MANUAL INFORMATION:
Refer to the 1991-93 Service Manual, Automatic Transaxle On-Vehicle Service Section 7A for proper On-Vehicle Service to remove and replace a
HYDRA-MATIC 4T60-E transaxle.
WARRANTY INFORMATION:
Labor time should be charged under Operation Number K7000 for "Transaxle Assembly-Replace" from the appropriate 1991-93 Labor Time Guide.
