THIS BULLETIN SUPERSEDES BULLETIN NUMBER 90-74T60-117 FOR THE HYDRA-MATIC 4T60. IT CONTAINS NEW INFORMATION ABOUT HYDRA-MATIC 4T60E SRTA AVAILABILITY.

BULLETIN COVERS:

This bulletin expands the list of available SRTA part numbers. The attached SRTA chart provides a complete list of the 1984 through 1992 models available..Consult your Parts catalogue for the specific usage.

SRTA ADVANTAGES:

- A SRTA is the product of a highly successful, customer satisfaction driven program which provides the technician with a service alternative for addressing diagnostic and overhaul concerns.

- All SRTA units are designed and remanufactured to current engineering specifications and are often less costly than major overhaul.

IN THE INTEREST OF CUSTOMER SATISFACTION, SRTA MODELS SHOULD ONLY BE CONSIDERED WHEN THE PROJECTED COST OF REPAIR EXCEEDS THE COST OF A SRTA REPLACEMENT.

SERVICE NOTE:

Cooler flushing MUST be performed whenever a transmission/transaxle is removed for service. It is essential to flush the cooler for SRTA installation, major overhaul, in any case of pump or torque converter replacement, or when fluid contamination is suspected. Time allowance has been added to operation K7000 (Transmission Removal and Replacement). Use Kent-Moore tool J35944 to flush the cooler.

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.
