Should an Automatic Transmission Car Be Warmed Up in N or P Gear?

[McRose]

For warming up an automatic transmission car, both N (Neutral) gear and P (Park) gear are acceptable, but using N gear requires engaging the handbrake. Additionally, warming up in P gear locks all four wheels of the vehicle, and the engine speed in P gear is relatively higher, resulting in a faster warm-up process. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, and L. For general driving needs, using the P gear for parking, R gear for reversing, N gear for neutral, and D gear for driving is sufficient. However, in certain special driving conditions, other functional gears may be required.
