Code P0735 Mitsubishi Description

The P0735 diagnostic trouble code (DTC) for Mitsubishi vehicles indicates that there is an issue with gear 5 having an incorrect ratio. In an automatic transmission system, each gear is responsible for a specific speed range and torque output. When the transmission control module (TCM) detects that the gear ratio in gear 5 does not match the expected ratio, it triggers this code. This discrepancy can lead to various performance issues and potential long-term damage if not addressed promptly.
