A/T CONTROL SYSTEM: Torque Converter Clutch Solenoid Valve
The torque converter clutch solenoid valve is activated, with the gear in D2, D3, D4, D5, D6, D7, M2, M3, M4, M5, M6 and M7 by the TCM in response to signals transmitted from the output speed sensor and accelerator pedal position sensor. Torque converter clutch piston operation will then be controlled.
Torque Converter
Check torque converter one-way clutch using a check tool as shown in the figure below.
