What Causes an Automatic Transmission Car Not to Shift Gears?

[VonRuth]

Reasons why an automatic transmission car cannot engage gears: gear lock, or not fully braking when parking, directly shifting into P gear, causing gear braking instead of brake braking. Automatic transmission means the driver does not need to manually shift gears; the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. Gear Introduction: Generally, there are six automatic transmission gears: P, R, N, D, S, L. Automatic Transmission Introduction: Automatic transmission uses an automatic gearbox, employing planetary gear mechanisms for shifting, which can automatically change gears based on the degree of the accelerator pedal and changes in vehicle speed. Driving an automatic transmission car only requires using the parking gear P, reverse gear R, neutral gear N, and drive gear D, which can fully meet the needs of general driving.
