Why does an automatic transmission always start in 2nd gear?
1 Answers
Automatic transmission always starting in 2nd gear is caused by a faulty transmission separator. Here is an introduction about the transmission: Introduction: The transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine, and can fixedly or stepwise change the transmission ratio between the output and input shafts. Function: It can be categorized into stepped, continuously variable, and integrated transmissions, with functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations; while automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.
