Effective October 1, 1987, the THM 125C Service Replacement Transmission Assembly (SRTA) Program begins. At the start of the program, SRTA models can be ordered for all 1982 through 1986 THM 125C model applications from your local General Motors Service Parts Operation (GMSPO) Parts Distribution Center. In early 1988, the THM 125C SRTA Program will be expanded to also include 1987 and 1988 model year applications.

The THM 125C SRTA program is customer satisfaction driven and parallels the existing THM 440-T4 and 700-R4 programs. Unit replacement through SRTA represents an additional method of service which General Motors dealers and Divisions can offer the customer in instances where major overhaul is necessary.
