A transmission system has a housing including a wall and a gear support extending from the wall. The gear support has an outer surface and an inner surface defining a passage. The outer surface includes a seal receiving portion and a seal support axially spaced from the seal receiving portion. A seal is positioned about the gear support at the seal receiving portion. A sleeve is arranged on the outer surface of the gear support between the wall and the seal and a pump drive gear is mounted on the gear support and is supported by the sleeve. The pump drive gear includes an outer toothed surface, an inner surface, and a bushing arranged on the inner surface, the bushing extending about the sleeve.

Pump drive architecture for an automatic transmission

A transfer case pump includes an oil pump, a cover assembly, and a torque transfer mechanism. The oil pump has a pump shaft, and is configured to pressurize a lubricant in response to a rotation of the pump shaft. The pump shaft rotates around a pump axis. The pump axis is parallel to a rear axis of a rear shaft. The pump axis is offset from the rear axis. The cover assembly has a channel configured to transfer the lubricant from the oil pump to the rear shaft. The cover assembly extends around the rear shaft and around the pump shaft. The torque transfer mechanism is configured to transfer a torque from the rear shaft to the pump shaft.

A friction clutch assembly for an automatic transmission is provided. The friction clutch assembly is configured to move between an applied position and a released or disengaged position. A plurality of clutch plates may include friction plates and interleaved reaction plates, plus an apply plate and a backing plate. A separator feature is disposed adjacent to at least one of the reaction plates, the friction plates, the apply plate, and the backing plate. At least one of the reaction plates, the friction plates, the apply plate, and the backing plate defines a passage configured to allow fluid to flow through the friction clutch assembly and around the separator feature.

A motor vehicle planetary axis transfer gearbox system includes a connective housing connecting an engine to a transmission of a motor vehicle with the transmission being positioned forward of the engine. An axis of an engine output shaft is oriented substantially parallel to an axis of a transmission input shaft. Both the axis of the engine output shaft and the axis of the transmission input shaft are oriented substantially perpendicular to a central axis of the motor vehicle. A planetary gear set is connected to one of the engine output shaft or the transmission input shaft acting to reverse a direction of rotation of either the engine output shaft or the transmission input shaft to match a direction of rotation of both the engine output shaft and the transmission input shaft. A drive chain connects the engine output shaft to the transmission input shaft.
