DTC P0741
- Torque Converter Clutch (TCC) - Stuck Off
DTC P0742
- Torque Converter Clutch (TCC) - Stuck On
Circuit/System Description
The torque converter clutch (TCC) pressure control (PC) solenoid is part of the control solenoid valve assembly which has no serviceable parts.
The TCC PC solenoid is a normally low pressure control solenoid. The TCC PC solenoid regulates transmission fluid to the TCC regulator valve in
the lower valve body and the TCC control valve in the pump cover. When vehicle operating conditions are appropriate to apply the converter
clutch, the transmission control module (TCM) will increase TCC PC current flow (duty cycle) to the TCC solenoid. The TCC PC solenoid directs
fluid pressure to move the TCC control valve to the apply position, and moves the TCC regulator apply valve to the regulating position. The TCC

DTC P2714
- Pressure Control (PC) Solenoid 4 - Stuck Off
DTC P2715
- Pressure Control (PC) Solenoid 4 - Stuck On
Circuit/System Description
The clutch pressure control solenoid 4 is part of the control solenoid valve assembly and is not serviced separately. The transmission control
module supplies 12 volts to the clutch pressure control solenoid 4 through the high side driver 1 circuit. The transmission control module controls
the clutch pressure control solenoid 4 through the clutch pressure control solenoid 4 control circuit. The normally low clutch pressure control
solenoid 4 flows fluid to the 1-3 clutch when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 4
regulates the transmission fluid pressure to the 1-3 clutch.
Conditions for Running the DTC
* The engine run time is greater than 1 second.
* Shift solenoid valve 1 is not in a transition state.
* The transmission line pressure is greater than 370 kPa (54 psi) and not fluctuating by greater than 30 kPa (4 psi).
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Control solenoid valve assembly replacement. Refer to Control Module References (See: Testing and Inspection/Programming and
Relearning) for replacement, setup, and programming.
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
