Disclosed are embodiments generally directed to a heat exchange system comprising a heat exchange module (HEM) that is strategically positioned within the vehicle and supports a combined lubrication system providing lubrication functionality for the vehicle. The HEM is positioned between an inverter and a gear box within the example electric vehicle. The HEM includes a plurality of ports and corresponding passages for coolant flow and oil flow.

A marine transmission includes a synchronizer on a counter rotating shaft to shift into a high speed gear. The synchronizer includes friction surfaces on both sides of the gear body for the high speed gear. The high speed gear mesh is helical and generates axial force that enhances the torque carrying capacity of synchronizing friction surfaces, thereby enabling the shifting into the high speed gear without torque interrupt.

A multi-mode hybrid transmission for transmitting power from a prime mover and a stored source of energy to a final drive shaft. The transmission may include an input shaft to receive torque from the prime mover, a countershaft operatively coupled to the final drive shaft, a plurality of gear pairs each defining a torque path from the input shaft to the countershaft, a synchromesh clutch assembly to selectively couple the input shaft with a desired gear pair, and first and second electric machines rotatably carried by the input shaft. The first electric machine can provide a motive force to the final drive shaft and the second electric machine can covert rotary speed of the input shaft into electrical energy. Additionally, the first and second electric machines can provide supplemental torque to the output shaft during periods of reduced torque from the prime mover associated with a change in torque path.
