About P0829

P0829 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0829 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code is set when the control module detects an issue with the shift from 5th to 6th gear in an automatic transmission. The code is typically triggered when the transmission control module (TCM) identifies an abnormality in the shifting process, such as a delay in engaging the 6th gear, incomplete shift, or an inability to shift into the 6th gear. This could be due to mechanical issues within the transmission, problems with the shift solenoids, or issues with the transmission fluid pressure during the shift process.
