Gearbox Fault Appears Immediately After Battery Replacement

A gearbox warning after battery work should be assessed with the electrical and repair timeline preserved. The timing does not prove the transmission control unit has failed, and a reset should not be used as a substitute for checking the actual warning.

Compare before and after

State why the battery was replaced, whether the vehicle had starting problems beforehand and whether power was interrupted during other work. Provide the full scan, including supply or communication records outside the gearbox controller.

Do not run an adaptation procedure simply because the battery was changed. Requirements vary, and the workshop should identify what the vehicle actually needs. If gear selection or drive is unreliable, seek advice before using it. For a specialist enquiry, include battery-work details and the exact transmission identification. Ask what evidence distinguishes a temporary event record from a current supply, setup or gearbox problem requiring further repair.
