What Does P2761 Mean?
The TCM has detected an open circuit in the TCC pressure control solenoid control circuit. This means there is a break in the electrical path preventing current flow, indicating a complete loss of electrical continuity between the TCM and solenoid.
Common Causes
35%
Broken wire in transmission wiring harness
30%
Disconnected or badly corroded transmission connector
20%
Open circuit within TCC pressure control solenoid
10%
Damaged internal transmission harness or connector
5%
Failed TCM output driver circuit
Diagnostic Steps
1
Step 1: Visually inspect transmission external connector for disconnection, damage, or pushed-out pins
2
Step 2: Measure resistance from TCM connector to solenoid connector (should be less than 1 ohm)
3
Step 3: Disconnect solenoid and measure resistance of solenoid itself (typically 10-30 ohms)
4
Step 4: Backprobe TCM connector and check for battery voltage on power supply circuit with key on
5
Step 5: If external wiring is good, remove transmission pan to inspect internal harness and solenoid connection
Estimated Repair Cost
$150 - $1,200
Parts + labor, varies by vehicle and location
The TCM has detected an open circuit in the TCC pressure control solenoid control circuit. This means there is a break in the electrical path preventing current flow, indicating a complete loss of electrical continuity between the TCM and solenoid.
The most common cause of P2761 (Torque Converter Clutch Pressure Control Solenoid Control Circuit/Open) is: Broken wire in transmission wiring harness
Typical repair costs for P2761 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle remains drivable but torque converter will not lock, resulting in poor fuel economy and increased transmission temperatures. Extended driving may cause transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2761 to identify the root cause.
