THIS BULLETIN HAS BEEN REVISED TO CHANGE INFORMATION UNDER "SERVICE PARTS INFORMATION" AND TO ADD 1991 SRTA MODEL APPLICATIONS.
The start of the Hydra-Matic 3T40 (THM 125C) SRTA model replacement program. See "SERVICE PARTS INFORMATION" for a complete list of the 1982 through 1991 Hydra-Matic 3T40 (THM 125C) 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 a major overhaul.
- GMSPO Parts Distribution Centers are committed to 48 hour maximum delivery time for all SRTA models, with no VIP charges.
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 line flushing MUST be performed whenever a transmission/transaxle is removed for service. It is essential to flush the cooler lines after SRTA installation, major overhaul, in any case of pump or torque converter replacement, or when fluid contamination is suspected. Published Labor Time Guide time allowances for K7000 (Transmission Removal and Replacement) include an allowance for cooler line flush for 1987 through 1991 model year vehicles. For 1982 through 1986 model year vehicles, add 0.6 hours for cooler line flush to Removal and Replacement allowance.

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.
