Solenoid Relay Valve
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
45 enable (51) fluid is routed to the solenoid relay valve and replaces exhausting 3rd gear band apply (46) fluid to hold the valve in the released position. With the solenoid relay valve in the released position, lock up control (12) fluid is allowed to enter the TCC signal (13) fluid circuit. TCC signal (13) fluid is routed through the lock up relay valve and on to the lock up control valve in preparation for a possible torque converter clutch apply.
