Transmission Control Module Functionality Verification

WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: The Transmission Control Module Functionality Verification routine requires one person to drive the vehicle and another person to monitor the progress of the routine. Failure to follow this instruction may result in personal injury.

The Transmission Control Module Functionality Verification routine is used to verify the function of the transmission during a road test.

The Transmission Control Module Functionality Verification routine should be performed after installing a new valve block.

After completing the road test, check the transmission control module for DTCs and perform the relevant corrective actions.
