What does 6AT transmission mean?
2 Answers
6AT transmission means that the car has 6 forward gears, which means there are six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the numbers in front are different, they are all derivatives of automatic transmission technology. Hydraulic automatic transmissions achieve automatic shifting through a combination of hydraulic transmission and planetary gears. They are generally composed of a torque converter, planetary gear mechanism, shift execution mechanism, shift control system, shift operation mechanism, and other devices. AT transmissions do not use a clutch to shift gears, have fewer gears and larger changes, and provide smooth connections, making them easy to operate. This not only brings convenience to the driver but also comfort to the passengers.
I recently researched the 6AT transmission. Actually, 6AT is short for 6-speed automatic transmission, meaning an automatic shifting system with 6 forward gears. It uses a torque converter and computer control to sense vehicle speed and throttle, automatically shifting gears so we don't have to manually shift while driving. It feels particularly suitable for congested urban roads - novice drivers like me don't need to worry about stalling. The advantages are smooth shifting, high comfort, and optimized fuel economy. Compared to older 4AT transmissions, the two extra gears help keep engine RPM in a more fuel-efficient range. The downside may be slightly more complexity, occasional lag, and requiring regular transmission fluid changes for maintenance. Overall, it represents a milestone in automotive technology evolution, balancing practicality and performance. Many economy cars now use this configuration.
