Question: what is the difference between p and n in automatic transmission?
Answer: Most automatic gearboxes will let you select between 'P' (for park), 'R' (reverse), 'N' (neutral) and 'D' (drive). ... Reverse does as it says - acts the same as a reverse gear in a manual, and should be selected when you want to drive backwards. Neutral is the same as knocking a manual gearbox out of gear.
