1 vehicles · 1 makes · $200-$3,000 repair
Most Reported On
P2789 is an OBD-II diagnostic trouble code meaning “Clutch "A" Adaptive Learning at Limit.” This code, common on dual-clutch and automated-manual transmissions, indicates the transmission control module's adaptive learning for clutch "A" has reached its maximum programmed limit. The transmission continuously makes small software adjustments to compensate for normal clutch wear and keep shifts smooth. When those adjustments hit their ceiling, the system can no longer mask the wear, signaling that the clutch is near the end of its usable adjustment range. Continued driving can accelerate clutch slipping and overheating, so inspection is recommended. This code is most commonly reported on 2018-2025 Volkswagen Atlas, with repair costs ranging from $200 to $3,000.
