Abstract:
A transmission includes a torque converter stator with controllable blade angle. A controller adjust the blades by commanding fluid pressures in hydraulic circuits routed to the stator hub. The controller also adjust the torque capacity of a torque converter bypass clutch by commanding fluid pressures in hydraulic circuits routed to apply and release chambers. Various schemes are presented to multiplex hydraulic circuits to serve multiple functions.
