What is the Difference Between 4AT and 6AT Transmissions?
1 Answers
4AT and 6AT transmissions differ in the number of gears: a 4AT transmission has 4 forward gears, while a 6AT transmission has 6 forward gears. Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations. The functions of a transmission are: 1. To change the transmission ratio and expand the range of torque and speed variations of the driving wheels; 2. To enable the vehicle to reverse while maintaining the engine's rotation direction; 3. To use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifts or power output.
