THIS BULLETIN SUPERCEDES INFORMATION ON THE HYDRA-MATIC 4T60 (THM 440-T4) ONLY IN PRODUCT SERVICE BULLETIN 88-7-108.
This bulletin expands the list for all SRTA model applications. The SRTA Model Replacement Chart offers a complete list of the 1984 through 1990 SRTA models offered by Hydra-matic.
- A SRTA is the product of a highly successful, customer satisfaction driven program providing the technician with a service alternative when 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.
Cooler flushing MUST be performed whenever a transmission/transaxle is removed for service. It is essential to flush the cooler after 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) for 1987 and 1988 models. Add 0.6 hours to Removal and Replacement allowances for 1982 through 1986 models.

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.
