Which cars use Aisin transmission?
The vast majority of Toyota and Lexus vehicles use automatic transmissions built by Aisin, with 6- and 8-speed units common across many models. In practice, this means a large portion of the brands’ mainstream cars rely on Aisin gearboxes, though exact specs can vary by year and market.

How to confirm the exact transmission in your car
To verify whether a particular model uses an Aisin unit, check the vehicle's specifications on the window sticker or owner's manual, look up the construction code printed on the transmission itself, or use the VIN (vehicle identification number) in a build-spec or dealer database. Dealers and service manuals can provide the precise transmission family (for example, 6-speed vs 8-speed) assigned to a given configuration.
In summary, Aisin transmissions are a defining feature of many Toyota and Lexus cars, especially in recent generations. The Camry, RAV4, Highlander, ES, and RX are among the most commonly cited examples in mainstream markets, while other models and regions may vary by year and trim.
