SERVICE REPLACEMENT TRANS ASSY (SRTA) PART NUMBERS

SUBJECT: SERVICE REPLACEMENT TRANSMISSION PART NUMBERS - 4T60 (440-T4), THM 200-4R, 3T40, 4T60-E, 4

This bulletin supersedes DSIB 91-1-4 which should be discarded.

The following SRTA unit part number list indicates what model numbers are available from GMSPO and which units they replace. A description of the application is provided where possible.

NOTES:

o All SRTA units are designed and remanufactured to current engineering specifications.

o SRTA models should only be considered when the projected cost of repair exceeds the cost of a SRTA replacement.

o Cooler flushing must be performed whenever a transmission is removed for service.

IMPORTANT: Beginning with the 1990 model, GMSPO does not automatically consider every SRTA order "VIP" status. To expedite delivery you must specify "VIP" on your order, regardless of model year.

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.
