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 PRQJECTED 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.
