Claim 17:
18. A method of operating a torque converter including a cover, an impeller including an impeller shell, connected to the cover, and at least one impeller blade, a turbine in fluid communication with the impeller and including a turbine shell and at least one turbine blade, a stator assembly including a combination washer and seal, and a stator non-rotatably connected to a stator shaft and including at least one stator blade axially disposed between the turbine and the impeller, the method comprising:
applying rotational torque to the cover;
rotating, with the cover, the impeller shell at a first speed;
rotating, with the impeller, the turbine at a second speed less than the first speed;
clamping, between the turbine shell and the stator assembly, a first portion of the combination washer and seal;
rotating the turbine shell with respect to at least a portion of the stator assembly;
sealing a second portion of the combination washer and seal directly against the stator shaft;
flowing a pressurized fluid into a chamber defined at least in part by the cover and the impeller shell; and,
blocking, with the second portion of the combination washer and seal, a flow of the pressurized fluid between the stator shaft and the combination washer and seal.
