Optimal shift speeds for an automatic transmission (AT) depend on the vehicle, transmission model, and driving mode. However, in general, automatic transmissions will typically upshift at the following approximate speeds:
Normal Mode:
* 1st gear: 0-20 km/h
* 2nd gear: 15-30 km/h
* 3rd gear: 25-40 km/h
* 4th gear: 35-50 km/h
* 5th gear: 45-60 km/h
* 6th gear: 60 km/h+ (if equipped)
Sport mode (sports):
* Shifting occurs at higher engine speeds, resulting in more aggressive driving.
*Shift timing may vary depending on the specific vehicle and transmission model.
Economy mode (economical):
* Shifting occurs at lower engine speeds, which improves fuel economy.
* Switching times may be slower than normal.
These shift speeds are designed to keep the engine and transmission running smoothly and efficiently. However, actual shift points may vary depending on driving conditions such as acceleration, load and temperature.
