P2783
Torque Converter Temperature Too High
Transmission
Generic OBD-II
Medium
What it means
P2783 sets when the transmission control module sees torque-converter or transmission fluid temperature above its safe limit. Overheating usually comes from low or worn-out fluid, a slipping torque-converter clutch, or heavy load with poor cooling. High heat rapidly degrades the fluid and can damage the transmission, so it's worth acting on quickly.
Medium
Can I keep driving? Ease off — high transmission temperature can cause lasting damage; stop and let it cool, avoid towing or hard driving, and fix the cause soon.
Common symptoms
What you'll notice
- Transmission temperature or overheat warning
- Harsh, slipping, or delayed shifts
- Torque-converter shudder or vibration when locking up
- Reduced power or limp mode when hot
- Burnt smell from the transmission fluid
Common causes
Most likely first
- Low or old/degraded transmission fluidLikely
- Towing, overloading, or a blocked transmission cooler restricting heat removalCommon
- Failing torque-converter clutch or its lock-up (TCC) solenoid causing slipCommon
- Internal clutch wear or slippage generating excess heatLess often
- Faulty transmission fluid temperature sensor reading highLess often
How to diagnose & fix
Work through it in order
- Let the transmission cool, then check fluid level and condition (color/smell).
- Inspect the transmission cooler and airflow for restriction or blockage.
- Scan for torque-converter clutch codes (e.g. P0741) that point to TCC slip.
- Test the TCC solenoid and command lock-up with a scan tool.
- If fluid is burnt or contaminated, service or rebuild the transmission before further damage.
FAQ
Quick answers
Is it safe to drive with P2783?+
Only gently and briefly. Sustained high transmission temperature degrades the fluid and can permanently damage the transmission — stop, let it cool, and address the cause.
Can I just clear P2783?+
Clearing it doesn't lower the temperature. It will return whenever the transmission overheats again until the underlying cause is fixed.
