• According to signals from switches and sensors, direct electronic shift control drives the duty-cycle solenoid valves (shift solenoid valves A, B, C, F), regulates clutch pressure to suit engine load and vehicle speed, and electronically controls clutch pressure directly.
• As a result, minute hydraulic control is possible, unlike with conventional clutch engagement pressure control using an accumulator.
• Even for select lever operation, the TCM provides the optimum torque capacity of clutch to the engagement- and release-side clutches according to the transmission input torque (turbine torque).
