Abstract
An electronically controlled power shift transmission for a vehicle includes an oil pressure source which generates oil pressure, a clutch which is adapted to be engaged to move the vehicle when oil pressure is supplied to the clutch, a shift valve which is movable between a first position in which oil pressure is supplied to the clutch and a second position in which oil pressure to the clutch is cut off, and a solenoid valve for changing the position of the shift valve. The shift valve drains the oil pressure in the clutch when the shift valve cuts off the oil pressure supplied to the clutch.
