The 1992 HYDRA-MATIC 4L80-E/4L80-EHD Service Replacement Transmission Assembly (SRTA) Program began on September 1, 1991. SRTA models can be ordered for all 1992 HYDRA-MATIC 4L80-E/4L80-EHD model applications from your local General Motors Service Parts Operation (GMSPO) Distribution Center.

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 INFORMATION:
Cooler flushing MUST be performed whenever a transmission is removed for service. It is essential to flush the cooler before SRTA installation, major overhaul, in any case of pump or torque converter replacement, or when fluid contamination is suspected. When catastrophic damage has occurred, resulting in heavy metal contamination, replacement of the oil cooler is also recommended.
