# CAMPAIGN:TRANSAXLE DISTRESS DUE TO PREMATURE WEAR OF SPRO.

DATE: MARCH 1994

#### SUBJECT: 4T60-E TRANSAXLE DISTRESS DUE TO PREMATURE WEAR OF THE DRIVEN SPROCKET

#### IMPORTANT: THIS CAMPAIGN BULLETIN LIFTS THE STOP DELIVERY NOTICE (OLDSMOBILE DCS NO. 94-073, DATED MARCH 11, 1994) ON ALL NON-INVOLVED VEHICLES. INVOLVED VEHICLES, AS INDICATED BY VIN (VEHICLE IDENTIFICATION NUMBER) COMPUTER LISTINGS, MUST BE INSPECTED OR INSPECTED AND CORRECTED BEFORE SALE. IF YOU DO NOT RECEIVE A VIN COMPUTER LISTING WITH THIS BULLETIN, OUR RECORDS INDICATE YOU HAVE NO INVOLVED VEHICLES.

#### CONDITION:

GENERAL MOTORS HAS DETERMINED THAT CERTAIN 1994 A/H/N/K BODY VEHICLES WITH THE HYDRA-MATIC 4T60-E TRANSAXLE MAY CONTAIN A DRIVEN SPROCKET THAT WILL WEAR PREMATURELY, RESULTING IN A LOW MILEAGE DURABILITY CONDITION. THIS CONDITION COULD CAUSE THE TRANSAXLE TO BECOME NOISY AND EVENTUALLY TO BECOME INOPERATIVE.

TO PREVENT THIS CONDITION FROM OCCURRING, RETAILERS ARE TO INSPECT THE TRANSAXLE FOR A SPECIFIC JULIAN DATE CODE AND REPLACE THE TRANSAXLE WITH A NEW TRANSAXLE, IF NECESSARY.

#### VEHICLES INVOLVED:
