Is It Normal for a New Car with Aisin 6AT to Have Gear Shift Jerks?
2 Answers
AT transmissions having jerking sensations is normal. It is completely normal for AT transmissions to exhibit jerking sensations. If you want to avoid this kind of jerking sensation, you can opt for a model with a CVT transmission, as CVT transmissions do not exhibit any jerking sensations at all. Below is some relevant information about AT transmissions: 1. Composition: AT transmissions achieve automatic shifting through a combination of hydraulic transmission and planetary gears. They generally consist of components such as a torque converter, planetary gear mechanism, shift execution mechanism, shift control system, and shift operation mechanism. 2. Advantages: AT transmissions do not require a clutch for shifting, have fewer gears with significant changes, and provide smooth connections, making them easy to operate. This not only offers convenience to the driver but also ensures comfort for passengers.
When I first got my new car with the Aisin 6AT transmission, I also wondered if the gear shift hesitation was a defect. As someone who has studied automotive drivetrains, I must say Aisin's 6AT is renowned for its smoothness, but slight hesitation in a new car isn't uncommon. This is because the transmission needs a break-in period where components are adapting to each other, while hydraulic pressure and the electronic control unit are learning your driving habits. During the first few weeks of driving, if you only notice minor jolts during aggressive acceleration or gear changes, it's generally normal. Pay attention to the frequency and intensity of the hesitation - if it violently jerks like being pushed every time, or is accompanied by abnormal noises, then you should check for oil quality or sensor issues. Since the car is under warranty, I recommend documenting the symptoms and visiting the dealership to have technicians scan for trouble codes as a precaution. Don't lose big for small gains.
