How much transmission fluid does an Aisin 6AT transmission require?
2 Answers
Aisin 6AT transmission fluid replacement using a circulation machine requires approximately 10 liters, while gravity replacement requires about 4-6 liters. Different fluid replacement methods use varying amounts, and there are two modes to choose from during maintenance. The circulation method offers better results by removing impurities from the bottom and keeping the internal components cleaner. Below is more information about transmission fluid: 1. Automatic transmission fluid not only lubricates, cools, dampens vibrations, prevents rust, and cools, but its primary function is to transfer kinetic energy. Transmission fluid needs to be replaced after a certain period of operation. 2. Automatic transmission fluid also accumulates carbon deposits and wear particles over time, so it should be replaced periodically based on mileage. Japanese and Korean models are recommended for replacement every 60,000 kilometers, American models every 50,000 kilometers, and German models every 70,000 kilometers. 3. The Aisin 6AT transmission has a filter screen, which is a mesh type and can also be considered maintenance-free. 4. Transmission fluid operates in a high-temperature, high-pressure environment, and degradation and aging occur continuously during operation.
I've been driving for over 20 years and have operated many vehicles equipped with Aisin 6AT transmissions, such as certain Toyota and Ford SUVs. The transmission fluid quantity isn't fixed - typically requiring 4 to 8 liters per change depending on the model and drainage method. For example, when I drove a Corolla, the manual specified about 5 liters for gravity drainage, while flush-style drainage might need up to 7 liters. Remember to check fluid levels after warming up the vehicle in neutral - overfilling causes foaming and insufficient lubrication, while underfilling leads to gear wear. It's best to inspect fluid condition every 50,000 km using manufacturer-recommended specifications to extend transmission life and save repair costs. Always consult your owner's manual for accurate information as designs vary significantly between models - never rely on guesswork.
