Abstract: The first gear/reverse gate switch of the present invention includes a detent switch including a contact pin and a contact switch. When a manual transmission is shifted to a gear not in the first gear/reverse gate, the contact pin of the detent switch engages a recessed portion on a detent mechanism such that the contact pin does not engage the contact switch. This indicates that the transmission is not in a gear in the first gear/reverse gate. When the manual transmission is shifted to a gear in the first gear/reverse gate, the interlock moves the detent, pushing the contact pin into engagement with the contact switch. This indicates that the transmission is in a gear in the first gear/reverse gate. The spring forces the detent into a “relaxed position” when not in the first gear or the reverse gate, breaking switch contact.

Abstract: A vehicle transmission is provided having a housing that includes a support with an opening. The transmission also has a shaft with an axis of rotation and an end portion disposed within the support opening. A floating bearing assembly is arranged between the housing and the end portion so that the bearing assembly supports the end portion within the support opening thereby permitting the shaft to rotate about it axis within the support opening. The bearing assembly is movable along the axis of rotation relative to the housing to permit the shaft to move along the axis of rotation. An expansion member is arranged between the end portion and the housing to expand and contract with changing temperatures and maintain a desired end play tolerance between the end portion and the housing.

Abstract: A transmission has an integral lubrication system for delivering lubricating fluid to transmission components. The central portion of the lubrication system is conveniently located within the intermediate wall of the housing. The housing has an opening and inlet and outlet ports in fluid communication with the opening. A pumping assembly having inner and outer rotors is disposed within the opening for moving the fluid from the inlet port to the outlet port. A pump cover is attached to the intermediate wall over the opening and the rotors. An inlet and outlet chamber is defined within the opening by the pump cover and space between the inner and outer rotors. The inlet and outlet chambers are in fluid communication with the inlet and outlet ports, respectively, so the pump may draw the fluid from the inlet port into the inlet chamber and then expel the fluid into the outlet chamber and to the outlet port. The intermediate wall also contains integrally formed inlet and main feed passageways.

Abstract: A transmission having an integral lubrication (stem for delivering lubrication fluid to transmission components is provided. The lubrication system has a housing with a sump portion for holding the fluid. The lubrication system also includes a pump assembly with inlet and outlet chambers wherein the pump assembly moves the fluid from the inlet chamber to the outlet chamber. The housing has a collection system with an inlet passageway which interconnects the inlet chamber and the sump to provide fluid communication between them. The housing has a distribution system with a plurality of fluid distribution ports for delivering the fluid to the transmission components. The distribution system interconnects said distribution ports and said outlet chamber to provide fluid communication between them. First, second, and third passageways are integrally formed within various portions of the housing and deliver the fluid to bearing portions of the shafts and to the transmission gears.

Abstract: An input shaft bearing retainer for use in a vehicle transmission assembly maintains an input bearing in a desired position without the use of external fasteners such as bolts. The bearing retainer includes an exterior portion having a radially extending flange that is engaged between a transmission case outer wall and a clutch housing outer wall. Since the clutch housing outer wall remains fixed relative to the outer wall of the transmission case, the input bearing retainer is also maintained in place. The interface between an opening through the transmission case and the bearing retainer includes a seal member in the form of an O-ring to maintain a fluid tight seal at the opening of the transmission case.
