What is an AT Transmission?
2 Answers
AT stands for automatic transmission, which is also known as a torque converter transmission because it connects to the engine via a torque converter. The torque converter consists of three main components: the pump, turbine, and stator. The internal structure of an AT transmission is relatively complex, featuring multiple planetary gear sets that enable gear shifting and torque conversion. The advantages of AT transmissions include superior reliability and durability, as well as smoother gear shifts. Since it uses a torque converter to connect with the engine, the transmission fluid inside the torque converter can absorb some of the vibrations and jolts during gear shifts.
When I first heard about AT transmissions, I thought they were complicated. Later, while driving, I realized it's just an automatic transmission—no need to press the clutch pedal at all. The car automatically shifts gears based on speed, which spared me, a beginner, from panicking in city traffic jams. It uses a torque converter to transfer engine power to the wheels, ensuring smooth power delivery, and computer control makes gear shifts more responsive. It’s especially comfortable on long drives, reducing physical fatigue, though fuel consumption might be slightly higher than a manual transmission. Maintenance-wise, remember to change the transmission fluid every few tens of thousands of kilometers to avoid slipping issues. Modern models even have sport modes for better responsiveness, making it overall very user-friendly for daily driving.
