Is the AMT Transmission Prone to Failure?
2 Answers
Under normal usage conditions, the AMT transmission is not prone to failure. Introduction: The AMT transmission is an electromechanical-hydraulic integrated automatic transmission that combines the advantages of both AT (automatic) and MT (manual) transmissions. The working principle of the AMT transmission involves modifying the original mechanical transmission (manual gearbox), primarily altering the manual gear-shifting control part. That is, without changing the overall transmission structure, automation of gear shifting is achieved by installing a microcomputer-controlled automatic operating system. Therefore, the AMT essentially uses a computer to control a robotic system to perform two actions: operating the clutch and selecting gears. The core technology of the AMT is microcomputer control, and the quality of electronic technology will directly determine the performance and operational quality of the AMT. Currently, AMT transmissions are developing in two directions. On one hand, due to their structure being very similar to manual transmissions, they are used in some speed-oriented vehicle models. On the other hand, there is a trend toward simplification, making them visible in low-end vehicle models because of their cost-effectiveness.

I've driven a car with an AMT transmission and don't necessarily think it's prone to failure, but it largely depends on usage and maintenance. Frequent stop-and-go in city traffic accelerates clutch wear, leading to issues; my car has been driven for three years with some gearshift jerkiness but no major faults. The key is regular oil changes, maintaining smooth driving, and avoiding sudden throttle inputs. AMT is based on a modified manual transmission, featuring simple structure and low cost, making it less likely to have major failures, but the electronic control unit can be easily damaged if exposed to water or moisture. The general design lifespan is around 100,000 kilometers. A friend's car had its actuator fail in just two years due to frequent short-distance city driving, resulting in high repair costs. It's advisable to choose a brand with warranty when buying a new car, and proper daily maintenance can extend its lifespan.
