# NEW TRANSAXLE CASE 125,125C INFORMATION

#### Model Affected: All 1984 THM 125/125C Transaxles

Beginning with 1984 production of the THM 125/125C transaxles, a new transaxle case went into production. The changes in the 1984 THM 125/125C transaxle case are as follows:

1. The manual shaft hole was made larger in diameter to accommodate a larger manual shaft.

2. The manual shaft seal bore was made deeper to accommodate a double lip seal.

3. The transmission case casting was changed to accommodate a neutral start switch.

4. The Low and Reverse snap ring groove was moved toward the case sprocket face to accommodate thicker low and reverse clutch plates.

#### Notice: The new 1984 THM 125/125C transaxle case cannot be used to service any prior model years. The past model transaxle case (1983 model or earlier) cannot be used to service 1984 THM 125/125C transaxles.

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.
