Can 4S shops convert manual to automatic transmission?
2 Answers
The difference between manual transmission and automatic transmission lies in the gearbox. Manual transmission models are equipped with manual gearboxes, while automatic transmission models are equipped with automatic gearboxes. If a car is to be converted to automatic transmission at a 4S shop, the entire gearbox assembly needs to be replaced, which is not advisable. Common automatic transmissions include CVT transmissions, DCT transmissions, and AT transmissions. 1. DCT transmission: This transmission is also known as a dual-clutch transmission. The structure of this transmission differs significantly from manual transmissions, featuring two sets of clutches—one controlling odd-numbered gears and the other controlling even-numbered gears. Dual-clutch transmissions are compact, lightweight, offer fast gear shifts, and high transmission efficiency. 2. CVT transmission: This transmission is also called a continuously variable transmission. Its structure differs from other transmissions, featuring two conical pulleys and a steel belt in the CVT gearbox. 3. AT transmission: AT transmission, also known as torque converter transmission, is currently the most mature and widely used transmission. However, AT transmissions are heavy and bulky.
I've dealt with this quite a bit, and honestly, 4S shops basically won't help you convert a manual transmission to an automatic. First off, it's technically very complex—you'd need to replace the entire transmission system, gear lever, and control module, plus reprogram and rematch the engine. If not done right, you might end up wrecking the car. More importantly, vehicle inspections are strict these days. Unauthorized transmission modifications simply won’t pass, and since the DMV records still show it as a manual, getting caught means your car gets impounded. A friend of mine insisted on doing it, spent nearly 80,000 RMB, ended up with a half-dead car, and when he sold it, the value dropped by 30%. It’s really not worth it compared to just buying a new car. If you really want an automatic, I’d suggest trading in for a new one—many basic automatic models now start just over 100,000 RMB, which is way better than messing with an old car.
