Abstract: Assembly tools or aides assist the installation of chains and sprockets for a power take off in a motor vehicle automatic transmission. A first tool is an assembly clip having a semi-circular channel that engages the periphery of a chain disposed about a socket. The clip facilitates installation of the chain and a first sprocket through a slot or other opening in the side of a transmission housing while a second sprocket is being secured to a transmission shaft and the chain is engaged thereabout. The clip also facilitates positioning of the first sprocket in a desired location, typically on a driven shaft while retaining the chain thereabout. A second tool includes a pair of elongate, parallel pins which cooperate with the clip and the first sprocket to hold it in place during assembly of certain components of the transmission such as a power take off shaft or bulkhead.

Abstract: A shaft assembly for a powertrain includes a shaft having a cavity extending at least partially from a first axial end to a second axial end of the shaft and opening at at least one of the first axial end and the second axial end. For example, the shaft may be a balance shaft, a camshaft, or a transmission shaft. A first core plug is disposed in the cavity. The shaft and the core plug may be the same material, or may be different materials. The shaft may have a first density, first cross-sectional area, or first area modulus, and the core plug may have a different second density, second cross sectional area, or second area modulus which may be less than the first density, the first cross-sectional area, or the first area modulus.

Abstract: A transmission comprising housing and an axially compliant hub having a central plate with an axial opening and an outer circumference. The central plate is attached to the attached to the circumference with at least one strap spring. A method of managing axial stack up in a transmission is also disclosed where the transmission has a plurality of planetary gear sets aligned in series and at least one torque transmitting device. The planetary gear has gear members. The method includes providing a an axially compliant hub having a central plate with an axial opening and an outer circumference, wherein the central plate is attached to the attached to the circumference with at least one strap spring and wherein the outer circumference is connected to the torque transmitting device and wherein the central plate is connected to a gear member of a planetary gear set.
