- Uses a GSM with a rotary gear shift knob in place of a mechanical shifter for selecting P, R, N, D, M.
- The transmission hydraulic controls are modified using a park lock pawl valve connected to the park rod which unlocks and locks the park pawl from the carrier.
- Uses clutch B and D hydraulic pressure to push the system out of Park.
- Once out of Park, clutches A, B, C, D or F can continue to hold the system out of Park.
- A park lock pawl solenoid allows the system to remain out of Park when the engine is not running.
- The dual TR sensors indicate the state of the Park system and are not used to determine customer selected range, which is now provided by the GSM.
- A mechanical P override has been provided for in-plant use and towing. This consists of a cable running from the console to the transmission, a bracket and lever assembly mounted to the side of the transmission and a lever on the side of the transmission. In the override position the park lock pawl valve is held in the applied position to keep the park pawl unlocked from the carrier.
