A shaft system for an automatic transmission includes a stator support shaft having an internal axial bore for receiving an input shaft, a forward engagement portion for engaging a stator of a torque converter of the automatic transmission and an integral stator support flange extending radially outward for engaging a stator support of the automatic transmission and transferring to the stator support substantially all of a torque load imposed on the stator support shaft by the stator. The stator support flange includes at least one oil flow bore positioned therein to supply oil between different components of the transmission.
