Code P0735 Land Rover Description

The P0735 diagnostic trouble code (DTC) for Land Rover vehicles indicates that there is an incorrect gear ratio detected in the transmission's fifth gear. This means that the transmission is not shifting properly into the correct gear ratio, which can lead to various performance issues. The transmission control module (TCM) monitors the gear ratios while the vehicle is in operation, and if it detects that the actual gear ratio does not match the expected gear ratio for fifth gear, it will trigger the P0735 code.
