Technical issues and repair guidelines

This transmission for RWD vehicles is very reliable as all Aisin transmissions with high torque capacity. In most cases, problems occur in old vehicles and mainly associated with their age. If the car owner keeps track of the thermostat condition, then the lifespan of the automatic transmission AW450-43LE can exceed the service life of the car itself.


The torque converter is the first component to get out of order in this transmission, then it leads problems with the worn-out oil pump and bushings. The repair kit of gaskets and seals is included in the common order for a complete reassembly of this transmission. Rare repair cases usually include replacement of the Direct package. In most cases friction friction components of this package are the first to get burnt because of high loads. Frequently, this transmission comes to the repair shop completely burnt friction elements. In such cases, specialists order a full kit of frictions as well as the kit of steel discs.
