P2783 Torque Converter Temperature Too High

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.

Likely causes

TCC control valve stuck in the apply position
Debris or varnish in the valve body
Restricted converter or cooler oil flow

Symptoms

  • MIL on
  • Changed shift and lockup behaviour
  • Transmission overheating, burnt fluid smell
