- TCC, PWM
- EPC with Silver Can & Bottom Connector > 1991-1993
- EPC with Black Can > 1994-2003

Shift A and B solenoids are available in an aftermarket product that is compatible for both uses. The dealer brand (GM) are sold individually for each shift. The electrical pressure control (EPC) is not sold as part of the master kit.
