A transmission (4) includes a case (6) having first (8) and second (10) case portions, an oil pump (42) supported on the first case portion (8) and a valve body (62) supported on the second case portion (10a). The valve body (62) regulates the pressure of the oil discharged by the oil pump (42). The oil pump (42) is provided with a pump manifold (64), and the manifold (64) includes a filter (66) which filters oil stored in an oil pan (70) beneath the transmission (4). An oil intake passage (58) is provided in the pump manifold (64), a starting end of the oil intake passage (58) communicating with the oil pan (70), and a terminating end of the oil intake passage (58) communicating with the oil pump (42) through the filter (66). The pump manifold (64) also includes an oil feed passage (76) for feeding oil from the oil pump to the valve body (62), and an oil return passage (78) for returning clean surplus oil from the valve body (62) into the oil intake passage (58) downstream of the filter (66). |
