Automatic transmission[edit]
Automatic transmissions traditionally have had a straight pattern, adopting the classic P-R-N-D gate, with "P" being to the front, topmost position (or "P" all the way to the left on a column-mounted shifter); the corresponding shift positions being:
- P = Park – transmission is mechanically locked in position for parking, via a parking pawl.
- R = Reverse – reverse motion
- N = Neutral – no drive applied to the wheels with the engine running
- D = Drive – forward motion with fully-automatic operation in all gears.
