Abstract: A hybrid module includes a torque converter and a clutch assembly. The torque converter includes a front cover. The clutch assembly includes a piston axially spaced from the front cover. The piston is axially slidable to engage the clutch assembly. The clutch assembly further includes a seal plate non-rotatably connected to the front cover and sealed to the piston. A seal is compressed between the seal plate and the front cover.

Abstract: A method of assembling a modular hybrid transmission (MHT) is provided including (a) assembling an emotor clutch on a clutch shaft to form a clutch assembly, (b) press-fitting a bushing into a centering plate to form a centering assembly, (c) connecting the centering assembly to a torque converter, (d) assembling the torque converter to the clutch assembly with the bushing on an end of the clutch shaft, and (e) inserting the clutch assembly and the torque converter into a transmission housing while maintaining the centering of the clutch shaft to the transmission housing via the centering assembly connected to the torque converter. The assembled MHT is also provided which eliminates the needle bearing according to the prior art, avoiding the potential for damage during assembly.

Abstract: A piston assembly for a transmission includes a piston and a washer connected to the piston. In one embodiment, the washer includes a circumferential ring that extends continuously about an inner diameter, wherein a cavity is defined between the piston and the washer. A bearing element is retained and centered on the washer by the circumferential ring.
