For 1990-2009 cars

# CAMPAIGN: TRANSAXLE IMPROPERLY STAMPED SECOND CLUTCH

#### SUBJECT: TRANSAXLE IMPROPERLY STAMPED SECOND CLUTCH REACTION (STEEL) PLATES

#### MODELS: Certain 1995 *GM Vehicles* with the 4T60-E Transaxle (RPO M13)

#### TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that certain 1995 *GM vehicles* with the HYDRA-MATIC 4T60-E transaxle may have been built with second clutch reaction (steel) plates that were improperly manufactured. This condition could result in premature wear of the second clutch assembly at low mileage and may cause the transaxle to lose second gear and eventually become inoperative.

To prevent these conditions from occurring, dealers are to replace the suspect transaxle with a new transaxle.

#### VEHICLES INVOLVED:

Involved are certain 1995 *GM vehicles* built with 4T60-E transaxle Julian Dates of 258, 259, 262 (may be stamped 292), 263 and 264 (September 15, 1994 through September 21, 1994).

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.
