The transmission brand used in the Corolla is Aisin. Established in 1969, Aisin is a world-renowned specialist in the research, development, and manufacturing of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin holds the highest global market share. The Corolla's manual transmission options include a 5-speed manual and a 6-speed manual, while its automatic transmission options feature a CVT (simulating 8 speeds) and an E-CVT continuously variable transmission. A continuously variable transmission does not have distinct gear positions. It operates similarly to an automatic transmission but differs in the way it changes speed ratios—instead of shifting through discrete gears, it provides a continuous and smooth power delivery. When using the Corolla's transmission in daily driving, pay attention to the following points: Do not delay transmission fluid changes for extended periods. Prolonged use of old transmission fluid can damage internal components such as bearings and the transmission housing. Avoid coasting in neutral for long durations. While some experienced drivers may coast in neutral with manual transmissions, doing so in an automatic transmission can cause overheating and harsh engagement when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers attempt to shift into reverse while still moving to showcase "smooth" operation, but this can severely damage transmission gears and lead to gear grinding over time. Avoid frequently climbing steep slopes in Drive (D). Automatic transmission vehicles may overheat under heavy load or upshift prematurely, resulting in insufficient power for climbing. In such cases, use manual mode to lock in lower gears or switch to Sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the transmission in Neutral (N). Towing with a rope or dragging the vehicle directly is not recommended.

As someone who enjoys tinkering with cars, I've studied the Toyota Corolla's transmission, which typically uses a continuously variable transmission, commonly known as CVT. Unlike traditional automatic transmissions with fixed gears, this design allows seamless gliding during acceleration, delivering an exceptionally smooth ride without jerking. Toyota employs this in many gasoline-powered Corollas due to its high efficiency and fuel economy, making it particularly practical in urban traffic. Some people worry about CVT reliability, but my experience shows that regular fluid checks can prevent issues—generally, the fluid should be changed every 40,000 kilometers. In the hybrid version of the Corolla, Toyota has upgraded to an eCVT, which combines with an electric motor for even greater energy efficiency. Manual transmission Corollas are relatively rare nowadays, mostly found in older models or specific regions—they offer a more engaging drive but aren't as hassle-free as CVTs. Overall, the CVT strikes a smart balance between performance and cost. If you prefer a quiet driving experience, you'll love it.

I've been driving a Corolla for many years with a CVT transmission, and it feels incredibly smooth. Accelerating is like gliding, with no jerky gear shifts, making traffic jams less frustrating. It's a big help in saving fuel—I've calculated it saves me tens of dollars a month compared to a manual transmission. The engine can be a bit noisy at times, but it's no issue on long drives with music playing. There are newer optimized versions, but my older Corolla is just as reliable. When buying a car, I recommend testing the startup and acceleration to feel the smoothness, and during maintenance, remember to check the transmission fluid—don't delay it too long.

When repairing cars, I noticed that most Corolla transmission issues are caused by CVT belt wear or fluid aging leading to gear shifting problems. Toyota CVTs are generally durable, but it's best to change the fluid every 40,000 kilometers to avoid oil leaks or increased noise. If the malfunction indicator light comes on, it might be a sensor issue which can be fixed at a small cost. Compared to manual transmissions, CVTs require less maintenance and hassle. Choosing a CVT when buying a car means less worry.
