A reaction shaft support for a motor vehicle transmission includes a fluid passage having a cored portion and a drilled portion. The reaction shaft support includes an axially extending cylindrical portion defining an axially extending cylindrical channel. The reaction shaft support additionally includes a radially oriented face. The fluid passage extending between the front face and the cylindrical channel. The cored portion of the fluid path radially extends from the cylindrical channel. The drilled portion of the fluid path axially extends from the front face to the cored portion.

A piston is reciprocable in a cylinder of a valve body. A spring in the cylinder has one end bearing against the piston. An abutment holds a retainer in bearing engagement with the opposite end of the spring to hold the spring under compression. The valve body has a slot through which the retainer may be introduced transversely into the cylinder when the spring is further compressed. The retainer has a locking tab. The valve body has an axial notch extending from the slot in a direction away from the spring to clear the tab when the spring is further compressed by a tool and the retainer is introduced. When the tool is withdrawn and the retainer is forced back against the abutment by the spring, the tab extends beyond the notch to be overlain and trapped or blocked by a portion of the valve body to prevent the retainer from falling out of the cylinder through the slot.

The present invention is a method of adjusting backlash for a north-south transaxle. The method includes the steps of forming a case having a first passageway extending longitudinally and a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally and a cavity at one end of the second passageway having an opening generally perpendicular to the passageway. The method also includes disposing a transmission assembly in the first passageway and a transfer assembly in the second passageway and a differential assembly in the cavity and engaging the transfer assembly. The method further includes preloading the differential assembly, determining the amount of backlash between the differential assembly and transfer assembly, and adjusting the backlash between the differential assembly and transfer assembly.

Method of adjustment for a north-south automatic transaxle

A north-south transaxle includes a case having a first passageway extending longitudinally and a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally. The transaxle also includes a transmission assembly disposed in the first passageway and having a first shaft portion extending through the first passageway at one end thereof and a transfer assembly disposed in the second passageway and having a second shaft portion extending through the second passageway at one end thereof. The transaxle includes first and second bearings rotatably supporting the first and second shaft portions in the first and second passageways, and an assembly for retaining the first and second bearings and the first and second shaft portions in the first and second passageways.
