Park by Wire
- Uses a GSM with a rotary dial or push buttons in place of a mechanical shifter as the customer interface 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 parking pawl from the carrier.
- Uses clutch C and F hydraulic pressure to push the system out of Park.
- Once out of Park, line pressure can continue to hold the system out of Park.
- A park lock pawl solenoid is used to allow 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.
