The invention comprises a park mechanism for an automatic transmission comprising a toothed wheel secured to the torque output shaft of the transmission and a park pawl mounted pivotally on a transmission housing. The pawl has a pawl tooth engageable with tooth spaces on the toothed wheel, thereby locking the transmission torque output shaft against rotary motion. Torsional damper elements are carried by the torque output shaft and by the toothed wheel. Damper elements are located between registering radial extensions of the toothed wheel on the inside diameter of the toothed wheel and on a hub that is secured drivably to the torque output shaft, thereby permitting limited toothed wheel motion relative to the torque output shaft cushioning inertia forces as the pawl tooth engages a tooth space on the toothed wheel.
