When it comes to diagnosing and repairing vehicle issues, one of the most common codes that can pop up is the Dodge Code P0729, which indicates a gear ratio error in the 6th gear. This code is triggered when the transmission control system checks the integrity of its data by comparing the gear ratio to a known gear ratio, and when the two don’t match, the code is set. This issue can cause the transmission to go into a limp-in mode after four ratio errors occur, and it is important to understand the causes and solutions to this issue in order to properly repair it.
