TO: ALL CHEVROLET DEALERS

THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN NO. 90-188-7A, DATED MARCH 1990. SERVICE PARTS INFORMATION HAS BEEN CHANGED AS WELL AS THE 1991 MODEL YEAR AND THE HYDRA-MATIC 3T40 (THM A-1) ADDED. ALL COPIES OF 90-188-7A SHOULD BE DISCARDED.

BULLETIN COVERS:

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.

SRTA ADVANTAGES:

- 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.

SERVICE NOTE:

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 (Trans. 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.
