Abstract
An automatic transmission includes a pressure adjusting unit that controls hydraulic pressure supplied to a transmission mechanism by the operation of a solenoid valve. A housing has a heat radiating portion for radiating heat to the outside and houses the pressure adjusting unit. A first connector is so arranged as to pass through the housing and has a control circuit unit electrically connected to the solenoid valve of the pressure adjusting unit. A second connector is electrically connected to an engine control unit outside the housing and engages with the first connector and the heat radiating portion. The second connector is electrically connected to the control circuit unit and presses the first connector onto the heat radiating portion.
