DTC codes / P28xx · Transmission / P2829
P2829 indicates that the transmission control module (TCM) has detected a performance fault or stuck-off condition in pressure control solenoid K, which is responsible for regulating hydraulic pressure within the automatic transmission. The TCM monitors the solenoid's electrical circuit and its effect on transmission pressure, and it sets this code when the commanded pressure does not match the actual pressure response or when the solenoid fails to actuate when commanded.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
