Aisin 8AT refers to the transmission model of Aisin, and there is only one model of Aisin 8AT. Below is the relevant introduction: Introduction to Transmission: A device that changes the speed ratio and direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Function: To change the transmission ratio between the engine and the wheels, enabling the engine to operate under optimal conditions, expanding the torque and speed transmitted to the driving wheels, and achieving different speeds. It allows the vehicle to reverse and includes a neutral setting.
The car I drive is equipped with the Aisin 8AT transmission, which comes in quite a few models. The main series include: the AWF8F35, used in mid-sized cars like the Toyota Camry, handling up to 350 Nm of torque; the AWF8F45, suitable for SUVs such as the Highlander, withstanding 450 Nm; and the AWF8F55, used in high-end Lexus models like the LS series, with a maximum of 550 Nm. Additionally, there are variants like the AWF8G30, used in brands like Subaru. Each model is matched with different engine types, so it's important to check carefully when buying a car, otherwise performance might be unstable. The advantages of Aisin transmissions are smooth shifting and fuel efficiency. For daily driving, it's recommended to regularly check the transmission fluid, and generally, maintenance every 50,000 km can extend its lifespan.
Over years of repairing cars, I've encountered various Aisin 8AT transmissions, which mainly come in three common models: The AWF8F35 series is suitable for sedan-type vehicles with a maximum torque of 350 Nm; the AWF8F45 series is used in SUVs like the Toyota RAV4, supporting up to 450 Nm; and the AWF8F55 series is designed for luxury models such as the Lexus RX, handling up to 550 Nm. Occasionally, you might come across versions like the AWF8G30, specifically designed for transverse-mounted engines. During installation, it's crucial to match the model label exactly as is to avoid risks of oil leakage or incorrect matching. Regular maintenance should include attention to the transmission fluid replacement cycle, typically checked every 40,000 to 60,000 kilometers, which can help prevent premature failures.
