P2763 Torque Converter Clutch Pressure Control Solenoid Control Circuit High

P2763 means the control circuit of the lockup pressure solenoid reads high. GM's 2018 T87A table treats it as a short to power, at 1.16 Ω or less to a voltage source while the driver is on, Type B. Its 2016 tables add variants: on the T76 six-speed the high-voltage flag also covers an open circuit and must persist 4.4 of 5 seconds over two trips; on the T54 CVT the module sets it when at least 750 mA is commanded but 200 mA or less flows for over 5 seconds. Subaru cites P2763 in bulletin 16-149-25 for the TR580 CVT in 2020–2023 Legacy, Outback, Crosstrek and Forester Wilderness: condensation can wet the valve-body connector, cured with a redesigned control valve plus connector cover. Ford's 2012 6R80 also files TCC driver faults here.

Likely causes

Moisture in the valve-body connector (Subaru TR580)
Control wire shorted to battery voltage
Open circuit where the maker includes it in this code (GM T76/T54)
Faulty TCM output stage

Symptoms

  • No converter lockup, higher cruise rpm
  • Transmission warning and MIL
  • Other solenoid high codes at the same time (Subaru)
