Abstract
Holding device for holding the selector gear servo valve in the reverse position when the manual valve is in the neutral or parking position and when the manual valve is moved to a forward position, hydraulic pressure in the servo valve overcomes the holding to move the servo valve to a forward position. Additionally, a control valve is provided for binding the servo valve in the reverse position even when the manual valve is moved to the forward position until hydraulic pressure of the hydraulic clutch for the second transmission train reaches a predetermined level.
