P2783Torque Converter Temperature Too High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2783 warns that the torque converter is at risk of overheating. Ford's 2012 OBD summary shows one concrete use in its 6F front-drive six-speed. There, two valves route oil to the converter clutch; if the control valve hangs in its applied setting, no oil flows through an open converter and it heats up. The hardware was designed so the PCM can expose this: in third gear or higher with the clutch commanded open, it switches on shift solenoid E, which moves the second valve. If the converter then locks although it should stay open, P2783 is stored. Ford made the fault MIL-relevant and changes shift and lockup schedules to keep the clutch engaged as much as possible. Unlike P0218, which watches a fluid temperature sensor, this code addresses the converter itself.
- What you may notice
- MIL on
- Changed shift and lockup behaviour
- Transmission overheating, burnt fluid smell
- Likely causes
- LikelyTCC control valve stuck in the apply position
- PossibleDebris or varnish in the valve body
- RareRestricted converter or cooler oil flow
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
