TRANSMISSION CONTROL SYSTEM

摘要

A control system used to change the gear ratio in a gear set regulated by a signal from an electronic control unit is disclosed. A transducer provides an output torque signal which is compared to other signals for controlling the gear change. The ratio change is accomplished through a friction element engaged by hydraulic pressure. A unique diaphragm and solenoid control valve is used responsive to the electronic control unit to follow a shift control ramp to insure a smooth shift.
