Is the Corolla transmission AT or CVT?
2 Answers
Corolla transmission is CVT. More information about AT and CVT is as follows: 1. AT is a hydraulic automatic transmission with a complex structure, consisting of a hydraulic torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. 2. CVT is a mechanical continuously variable automatic transmission, composed of two pairs of variable-diameter pulleys and a steel belt, connected to the engine and drive wheels respectively. During operation, speed can be changed by altering the diameter of the pulleys. 3. AT advantages: strong load capacity, high speed; AT disadvantages: high fuel consumption, complex structure. 4. CVT advantages: fuel-efficient and environmentally friendly, small size, low cost, simple structure; CVT disadvantages: low speed.
The Corolla uses a CVT transmission, which stands for continuously variable transmission, and this applies to most models, such as the 2023 version. I've driven it a few times, and it feels incredibly smooth, without the gear-shifting jerkiness you get with traditional AT transmissions. It's very fluid when accelerating. Fuel efficiency is one of its major advantages—it's noticeably more economical in city driving, saving about 1-2 liters per 100 kilometers compared to an AT. However, the engine noise is a bit louder during initial acceleration with a CVT, and some people complain about the humming sound, but you get used to it. I also recommend regular checks on the transmission fluid, changing it every 50,000 kilometers to avoid long-term dust buildup leading to system failures. Toyota's overall reliability is high, and a CVT can last seven or eight years without issues, making it worth considering.
