Lock-Up Control Solenoid Valves
The TCM controls torque converter lock-up by delivering an output signal to lock-up control solenoid valves "A" and "B" on lock-up control solenoid valve assembly. Lock-up control solenoid valves are activated in accordance with lock-up condition. See LOCK-UP CONTROL SOLENOID VALVE OPERATION table. Lock-up control solenoid valve assembly is located on transaxle. See Figure . Lock-up control solenoid valve "A" has a Yellow wire and solenoid valve "B" has a Green/Black wire.
