Abstract
A transmission includes a case having a front support that defines a reservoir, and a first passageway in fluid communication with the reservoir. The transmission also includes a torque converter having a bypass clutch having a piston disposed between a balance chamber and an apply chamber. The clutch fixes the turbine to the impeller in response to fluid pressure in the apply chamber exceeding fluid pressure in the balance chamber. The transmission further includes a hollow stator shaft fixed to the front support and a turbine shaft driveably connected to the turbine. The turbine shaft extends through the stator shaft and defines a second passageway in fluid communication with the first passageway and the balance chamber. The reservoir, the first passageway, the second passageway, and the balance chamber are arranged such that fluid travels from the reservoir to the balance chamber when the piston is de-stroked.
