Overhaul T56 6-Speed Overhaul: Operation

Transmission is equipped with a solenoid which operates a reverse lock-out assembly. Solenoid prevents operator from shifting transmission into Reverse when vehicle is moving forward. To enhance fuel economy, transmission is also equipped with a gear select solenoid, which inhibits 2nd and 3rd gears when shifting from 1st gear. Solenoid is activated when engine coolant temperature is greater than 122°F (50°C), vehicle speed is between 12-19 MPH and throttle opening is 35 percent or less.
