THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 21-01-91, DATED 01/28/91 WHICH SHOULD BE REMOVED FROM

>> SYMPTOM/CONDITION: <<
Vehicles equipped with an A-604 transaxle (Trans S/N KXXX-0891-XXXX), built prior to May 23, 1991, may exhibit lighting of the back up lamps
while the vehicle is being driven with the gear selector in the overdrive position. This condition is intermittent and may not be accompanied by fault
codes. Continued driving with this condition may cause clutch failure (most likely the 2-4 clutch).
In addition to the back up lamps coming on when the vehicle is being driven with the selector in the overdrive position, the following symptoms may also
exist:
^
Transaxle clutch drag.
^
Slowing of the vehicle.
^
Vehicle shudder (AWD vehicles only).
If the customer complains of any of these symptoms, perform the Repair Procedures listed.
