Driving with a failed ECU can damage your transmission. If your transmission has an internal problem as well, repairing the ECU will not solve the issue. We do not provide diagnostic services. It is your mechanic's responsibility to pinpoint the problem to the ECU. If you or someone else tried to repair your engine computer, we can evaluate and possibly repair it, but only in the case that no additional damage was created. Please note, not all modules are repairable.
