Why does my car move back and forth when I put it in park?

Your automatic transmission has a device known as a parking pawl. The parking pawl restricts the automatic transmission output shafts (and wheels) from rotating in either direction. When you move the shifter out of Park, it disengages the pin, letting your transmission output shaft and wheels move freely.

Does car move in parking gear?

The torque converter is there to allow slippage between the engine and transmission so that the car can be left in gear at a stop and not stall. That slippage means the car can roll if parked in gear. So manufacturers developed a dedicated mechanism (park) to lock the transmission to keep the car from rolling.

Can an automatic car move in park?

Most automatic gearboxes will let you select between ‘P’ (for park), ‘R’ (reverse), ‘N’ (neutral) and ‘D’ (drive). Park should only be used when you’re stopped and getting out of the car. This ‘locks’ the transmission, preventing it from rolling away (but you still need to apply the handbrake when parked as well).

What does it mean when you put your car in park and it rolls?

Rolls a Little Bit or a Few Inches: Mechanical Play is Normal. When you put an automatic transmission into park, the parking pawl will swing towards the output shaft, and those few inches of roll or “lurch” that you experience are caused by the small amount of space left over once the pawl is engaged.
