What do the letters on an automatic transmission mean?
1 Answers
Common letters on an automatic transmission include: P, R, N, D, S, etc. The following explains their meanings: Here is an introduction to the gears of an automatic transmission car: 1. P: Parking gear, starting gear. Engage this gear when parking and not in use, at which point the wheels are mechanically locked to prevent rolling. 2. R: Reverse gear. This gear can only be engaged when the vehicle is stopped. 3. N: Neutral gear. Use this gear for temporary stops. 4. D: Drive gear. When needing to shift gears, this can be accomplished through throttle control. 5. S: Sport mode. When this gear is engaged, gears can be freely switched, but the shifting timing is delayed, keeping the engine at high RPM for a period to increase the car's power. However, this gear will result in increased fuel consumption.
