Abstract

A transmission includes a stationary sleeve having an axis, and an oil pump cover extending radially outward with respect to the axis. The oil pump cover is formed with a bore receiving said stationary sleeve and a wall member defining the bore. The oil pump cover includes an annular flange formed integrally therewith and coupled with the stationary sleeve and axially disposed adjacent the bore to hold the oil pump cover in juxtaposed position with respect to the axis. Serrations are formed on an inner circumferential surface of the oil pump cover and an outer circumferential surface of the stationary sleeve. The annular flange of the oil pump cover engages a shoulder formed on a reduced diameter section of the stationary sleeve. Fluid passages are formed in the oil pump cover and the stationary sleeve and fluidly communicated with each other.
