Abstract
An apparatus for controlling a multi-speed, oil pressure operated type vehicle transmission connected to an engine through a torque converter wherein each drive train includes an oil pressure operated clutch and the low speed drive train also includes a one-way clutch engagement element, such as an oil pressure clutch or the like, interposed in each of said driving trains such that each driving train is established by oil supply to each said clutch. The apparatus includes a holding device for the highest speed drive train which is actuated when the brake operation is detected and the vehicle is stopped, which actuation provides a pressurized oil supply to the highest speed oil pressure operated clutch interposed in said high speed drive train to minimized the torque transmitted from the engine even though the pressurized oil is continuously supplied to the low speed oil pressure clutch interposed in said low speed driving train.
