Experienced Subaru Lineartronic CVT (TR690 / TR580) specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
Subaru's Lineartronic CVT uses a chain (TR690) rather than a push belt, making it different from Nissan and Honda CVTs. In AWD Subarus, the CVT integrates with the front/rear torque split. Generally more robust than Nissan's CVT, but fails from extended intervals and overheating. Chicago-area Subaru owners bring Outbacks and Foresters in regularly.
