P2769 Torque Converter Clutch Circuit Low

P2769 reports a low level on the converter clutch circuit, in practice a short to ground. It belongs to the P0740 family for converters with a single TCC solenoid, unlike P2764, which refers to a dedicated pressure control solenoid. Ford uses it in its 2024 OBD summary for the 6R80, 6R140, 10R60, 10R80 and the 8F front-drive units: P2769 carries failure byte 11 (short to ground), P2770 byte 12 (short to power) and P0740 byte 13 (open). The electrical test runs continuously and flags a mismatch between driver feedback and commanded state lasting 1.5 seconds. The TCM then disables lockup, so engine speed stays higher at cruise and fluid temperature climbs. A pinched harness at the case connector or a shorted coil are typical.

Likely causes

TCC control wire pinched or chafed to ground
TCC solenoid coil shorted
Damaged internal transmission harness or lead frame

Symptoms

  • No converter lockup
  • Higher rpm and fuel use at highway speed
  • Check engine lamp on
