P2770: Torque Converter Clutch Solenoid Circuit High

Standardized SAE J2012 code · P27xx — Transmission

What does P2770 mean?

The voltage on the TCC solenoid control circuit is above the calibrated maximum. Either the wire is shorted to battery voltage or the solenoid coil is open.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

  • Check engine or transmission warning light on
  • Harsh, delayed, or missing shifts
  • Possible limp mode (locked in one gear)
  • Slipping or shuddering during gear changes

Common causes

  • High Control wire shorted to battery
  • Medium Open solenoid coil
  • Low Connector pins corroded - high contact resistance

Likelihood is a general estimate across vehicles; your make and model may differ.
