Abstract
A control system for an automatic transmission for a vehicle with an electric vehicle speed detector, the automatic transmission including a torque converter with a semi-direct coupling mechanism hydraulically controllable of the degree of coupling. The control system comprises a signal processing circuit for processing an electrical vehicle speed signal to provide an electric control signal, and an electro-magnetic valve mechanism for selectively supplying a multi-staged hydraulic control pressure to the semi-direct coupling mechanism in accordance with the electric control signal. Automatic transmissions of the above type are applied to a vehicle with an electric vehicle speed detector, without any major change of existing production system and at an inexpensive cost.
