Why does an automatic car make a clunking sound when shifting into reverse?
1 Answers
An automatic car makes a clunking sound when shifting into reverse because the brake pedal is not pressed to the appropriate position or the car has not come to a complete stop before shifting into reverse. Before shifting into reverse, it is essential to ensure the car has fully stopped to avoid damaging the automatic transmission. There are three common types of automatic transmissions in cars: 1. AT transmission, also known as a torque converter transmission, connects to the engine via a torque converter and uses planetary gears for shifting and torque conversion; 2. Dual-clutch transmission (DCT), developed based on manual transmissions, has a structure similar to manual transmissions but includes an additional clutch and shift control mechanism; 3. CVT transmission, a relatively simple automatic transmission, consists of two cone pulleys and a steel belt that moves along the pulleys to enable shifting and torque conversion.
