ABSTRACT:
In a motor vehicle driveline having an automatic transmission driveably connected to a transfer case, a park gear, continually driveably connected through a planetary gear set to the drive wheels of the vehicle, is alternately fixed against rotation on the transfer case or released to rotate freely in response to movement of a gear selector having a park position. When the gear selector is moved to the park position, a pawl holds the drive wheels against rotation. When the gear selector is moved from the park position, the drive wheels are free to rotate without restraint of the park mechanism.
