Automatic transmission shift speeds vary depending on the specific vehicle and transmission type. However, as a rule, switching speeds look like this:
Legacy 3- and 4-speed transmissions:
* 1st gear: 0-20 km/h
* 2nd gear: 20-40 km/h
* 3rd gear: 40-60 km/h
* 4th gear (4-speed transmissions only): 60+ km/h
Modern 5-, 6- and 7-speed transmissions:
* 1st gear: 0-25 km/h
* 2nd gear: 25-45 km/h
* 3rd gear: 45-65 km/h
* 4th gear: 65-85 km/h
* 5th gear (only for 5-speed transmissions): 85-105 km/h
* 6th gear (only for 6-speed transmissions): 105-125 km/h
* 7th gear (7-speed transmissions only): 125+ km/h
Please note that these are estimates only and actual shift speeds may vary depending on driving patterns, vehicle load and transmission settings.
