Thanks for the info. You mention the transmission control module. Was that definitely the issue with your Opel? What was the fix?

While I cannot definitively confirm it's the exact same problem, the symptoms align closely. In my case, the root cause was indeed a defective control unit. Given the complexity of modern automatic transmissions and the potential for electronic faults, I would strongly advise taking your Ford CMAX to a qualified workshop for a thorough diagnosis. They'll be able to pinpoint the issue and provide an accurate repair estimate.

Thanks, that's useful. Took it to a shop and you were right - control unit was defective. 1000€ later, it's fixed.

Good day. This sounds remarkably similar to an issue I encountered with my previous Opel Insignia. The symptoms you describe, particularly the gear selection display malfunction coupled with shifting problems, suggest a potential sensor issue or a fault within the transmission control module. Have you checked for any error codes beyond the stored error you mentioned?
