# THM 125 OR 125C TRANSAXLE SLIPPING IN ALL RANGES

#### VEHICLES AFFECTED: ALL MODELS 1980 THROUGH 1986

A 1980 through 1986 THM 125 and 125C transaxle may exhibit a slipping in all ranges condition under hard acceleration and/or maneuvering operations, caused by oil pressure drop due to a cut or improperly seated oil strainer seal.

Oil strainer and seal kit P/N 8652910 (refer to Figure 1) can be used to replace oil strainer and seal kit P/N 8631951 (refer to Figure 2) on a 1980 through 1986 THM 125 or 125C transaxle that exhibits the slipping condition.

Either design can be used to service all years and all models as follows:

SERVICE INFORMATION

1. If replacement of the oil strainer during transaxle service is necessary remove the original seal from the case and use the new seal provided in the kit.

2. Always install the seal in the case first when installing the replacement oil strainer and seal assembly.

#### Important: Use the correct seal based on the design of the oil strainer filler neck. The 'O' ring seal is used with the short-shouldered neck, the lip seal is used with the long-shouldered neck.

Refer to the appropriate Service Manual for removal and installation procedures.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
