Electronic-Hydraulic Control System

Electronic Control Inputs And Outputs:

GENERAL
The electronic-hydraulic control system consists of various sensors and switches, a transmission control unit (TCU) and the hydraulic controller including solenoid valves. The system controls the transmission proper including shift control, lock-up control, overrunning clutch control, line pressure control, auto pattern select control and shift timing control. It also controls the AWD transfer clutch. In other words, the system detects various operating conditions from various input signals and sends output signals to shift solenoids 1, 2 and 3 and duty solenoids A, B and C (a total of six solenoids).
