Transmission Torque Converter Clutch (TCC) Relay (A/T)

TCC relay is located in right corner of engine compartment on fusible link box. Battery voltage is supplied to TCC relay on Blue/Black wire from the main relay. Main relay is mounted on ECM, located under left side of instrument panel, near kick panel.

Based on signals from TPS, ignition coil and Engine Coolant Temperature (ECT) sensor, ECM will ground TCC relay. If brake switch is closed, voltage will be provided through contacts of TCC relay, to fluid pressure switch on transmission. When fluid pressure switch closes, voltage will be applied to TCC solenoid to allow torque converter lock-up.
