P2789: Clutch A Adaptive Learning at Limit

Standardized SAE J2012 code · P27xx — Transmission

What does P2789 mean?

The adaptive learning that compensates for clutch A engagement point drift in a DCT has reached its limit. Clutch wear is at end of life.

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 Clutch worn beyond compensation range
  • Medium Actuator position drift

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