What does 6AT refer to?

6AT refers to 6 forward gears, which means there are 6 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 transmissions. AT is the commonly referred automatic transmission. Generally, the gears of an automatic transmission are divided into P, R, N, D, 2, 1, or L, etc. The correct maintenance methods for an automatic transmission are: 1. Check the automatic transmission fluid, test the viscosity with fingers, and replace the oil if it changes color or has a burnt smell; 2. Check the manual gear selection mechanism, adjust the connecting parts from the gear lever to the manual valve through connecting rods or cables, ensuring the position of the manual handle corresponds to the spring clip position inside the automatic transmission; 3. Adjust the brake band, all adjustment structures need to be adjusted to compensate for wear; 4. Check the braking performance of the parking gear, inspect and repair if there is no braking performance in the parking gear.
The 6AT refers to a 6-speed automatic transmission in cars. Having driven for many years, I find this setup quite practical. It features six forward gears, providing smooth shifting while driving—unlike manual transmissions that require manual gear changes every time—making it especially convenient in traffic jams. Compared to older 4AT models, the 6AT performs more smoothly on highways and offers better fuel efficiency, saving a bit on fuel costs per 100 kilometers. However, its more complex structure may lead to slightly higher maintenance costs than manual transmissions, though overall reliability remains high. I recall a long-distance trip where the 6AT-equipped car significantly reduced driving fatigue. While many cars now adopt transmissions with more gears or CVT technology, 6AT remains popular in the used car market due to its good cost-performance ratio. If you're car shopping on a budget, models with 6AT are worth considering.
6AT stands for 6-speed automatic transmission, which essentially means the gearbox has six speed ratio gears. I understand its working principle: it shifts gears via planetary gears and solenoid valve control. Compared to manual transmissions, it automatically matches engine speed to reduce jerky sensations. It delivers quick acceleration response, especially when starting—just a light press on the throttle ensures smoothness. A downside is that improper maintenance can lead to issues, such as delayed shifting caused by valve body failures or insufficient fluid. In daily use, I’ve noticed it helps reduce engine noise and enhances comfort. However, under heavy loads, fuel consumption may be slightly higher, performing a bit worse than modern CVTs. Overall, the 6AT is a classic version of automatic transmission, ideal for drivers who rarely modify their vehicles.
