SYMPTOM/CONDITION:
Some 41TE transaxles may exhibit a harsh 2-1 downshift. This condition may occur when coasting to a stop or after applying pressure to the accelerator
pedal at low vehicle speeds. Changes have been made to the Transmission Control Module (TCM) for the 1993 model year that significantly reduce 2-1
downshift harshness.
These new service controllers should only be used to repair vehicles with specific customer dissatisfaction with harsh 2-1 downshifts.
DIAGNOSIS:
1.
Confirm the 41TE transaxle fluid level is correct using the procedure in the appropriate service manual.
2.
Use the DRB II to read Diagnostic Trouble Codes (DTC) that may exist and Clutch Volume Indexes (CVI's) to determine if transaxle repair is
appropriate.
3.
Road test the vehicle to confirm 2-1 downshift harshness.
PARTS REQUIRED
REPAIR PROCEDURE:
This bulletin involves replacing the Transmission Control Module (TCM).
