Solenoid Valve 1 and 2

Solenoid valve 1 controls the line pressure to the clutch valves. Solenoid valve 1 is either ON or OFF. When the solenoid is turned ON, the line pressure is low. When the solenoid is turned OFF, the line pressure is high. Refer to Line Pressure .

Solenoid 2 controls the fluid flow to the clutch valve E or to the torque converter clutch (TCC) valve. When solenoid 2 is ON, fluid is directed to the TCC pressure valve. If the solenoid is switched OFF, fluid will flow to the inlet at clutch valve E.

The TCM monitors numerous inputs to determine the appropriate solenoid state combination and the appropriate transaxle gear for the vehicle operating conditions.

In Park and Neutral, solenoid valve 1 is ON. The line pressure flows to the safety valve and to the line pressure control valve by means of the solenoid valve.
