Torque Converter Temperature Too High (P2783)
The P2783 code indicates that the transmission control module (TCM) has detected the torque converter clutch (TCC) fluid temperature exceeding a calibrated threshold, typically above 270°F (132°C). This can be caused by excessive TCC slippage, low transmission fluid, a faulty TCC solenoid, or a restricted transmission cooler. Prolonged high temperature can damage the transmission.
01. Most Common Causes
- Low or contaminated transmission fluid
- Faulty torque converter clutch solenoid
- Stuck torque converter clutch
- Restricted transmission cooler or lines
- Excessive towing or heavy load
02. Symptoms You Will Notice
- Check Engine Light on
- Transmission overheating warning
- Slipping or shuddering during gear changes
- Reduced fuel economy
- Burning smell from transmission
03. Step-by-Step Diagnosis
Step 1: Check transmission fluid level and condition; top off or replace if necessary.
Step 2: Scan for additional codes and monitor TCC slip speed and fluid temperature with a scan tool.
Step 3: Inspect transmission cooler and lines for blockages or damage.
Step 4: Test TCC solenoid operation and circuit integrity.
Step 5: Perform a stall test to check torque converter operation.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, driving with high torque converter temperature can cause severe transmission damage. Have the vehicle inspected immediately.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Repairs range from a simple fluid change ($100-$200) to replacing the torque converter ($500-$1500) or solenoid ($200-$400).
