What Does P2769 Mean?
The TCM has detected lower than expected voltage or current in the torque converter clutch circuit. This indicates insufficient electrical signal to properly engage the torque converter lockup clutch.
Common Causes
35%
Faulty torque converter clutch solenoid with high internal resistance
30%
High resistance in wiring or poor ground connection
20%
Low transmission fluid level or pressure affecting solenoid operation
15%
TCM internal driver circuit weakness or failure
Diagnostic Steps
1
Step 1: Check transmission fluid level and condition; low fluid directly affects solenoid pressure
2
Step 2: Measure TCC solenoid resistance and compare to specifications (typically 10-30 ohms)
3
Step 3: Verify ground circuit integrity by measuring voltage drop during solenoid operation (should be less than 0.2V)
4
Step 4: Check system voltage during operation; low battery voltage can cause this code
5
Step 5: Monitor actual vs commanded TCC duty cycle with scan tool to identify control vs mechanical issues
Estimated Repair Cost
$200 - $1,000
Parts + labor, varies by vehicle and location
The TCM has detected lower than expected voltage or current in the torque converter clutch circuit. This indicates insufficient electrical signal to properly engage the torque converter lockup clutch.
The most common cause of P2769 (Torque Converter Clutch Circuit Low) is: Faulty torque converter clutch solenoid with high internal resistance
Typical repair costs for P2769 range from $200 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Torque converter may not lock up properly, causing reduced fuel economy and increased transmission heat. Safe to drive but extended operation without lockup may lead to transmission overheating and damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2769 to identify the root cause.
