In a support for use in an automatic transmission apparatus of the type having a transmission shaft for transmitting power, an annular hydraulic servo drum and a piston fitted in the hydraulic servo drum for engaging and disengaging a friction engaging means is described, wherein the support has an axially extending tubular supporting portion having an inner peripheral surface for supporting the transmission shaft, an outer peripheral surface for supporting an inner cylindrical portion of the hydraulic servo drum, and working oil passages formed and adapted for supplying and discharging a working oil to and from the hydraulic servo drum. The improvement consists of: a support body made of light material having a first radially extending oil passage leading from an oil pressure controller for supplying and discharging a working oil and communicating with the inner peripheral surface of the tubular supporting portion; an inner sleeve of a heavier material than the support body fitting on the inner peripheral surface of the tubular supporting portion to cover the inner axially extending oil groove thereby forming an oil passage for working oil; and an outer sleeve of a heavier material than the support body fitting on the outer peripheral surface of the tubular supporting portion.
