Aisin (formerly Aisin AW, part of the Toyota Group) is one of the largest automatic transmission manufacturers in the world. Its gearboxes appear under many different factory codes: the same Aisin unit can be a VW 09G, a Volvo TF-80SC, an Opel AF40 or a Peugeot AM6 depending on who installed it. This cross-branding makes Aisin one of the most important families in the aftermarket - and one where correct identification by transmission code matters more than the badge on the car.
Our store solutions: overhaul kits, friction and steel disc sets, solenoids, valve body components, torque converter parts, bushings, sealing kits and complete rebuild kits - OE, OEM and selected aftermarket, depending on the unit.
The intervals below are general MID Auto workshop guidance. The exact fluid specification, quantity, service procedure and interval must be confirmed by transmission code, VIN and the vehicle manufacturer’s documentation.
Many Aisin units are officially described as lifetime-filled, yet in service practice they are fluid-sensitive. As general MID Auto guidance: a service interval of 50,000-60,000 km with the exact specified fluid provides effective protection - and the specification differs by unit and installer (for example VW G 055 025 for the 09G, Toyota T-IV for older U-series, Toyota WS for later ones). Using a universal ATF instead of the correct specification is a leading cause of shudder and solenoid complaints.
