My 2007 F430 with 18k miles recently having issues as it won’t go to reverse after it warms up. 30 minutes drive and it won’t go to reverse. I was going shopping so I thought I deal with it when I finished. 2 hours later when I finished, car reverse no problem. I got home, again it won’t go to reverse. This happened summer or last year. I didn’t have time to look into it. Since I’ve bought Launch to adjust the PIS. My PIS reading was 4.19. I checked and when it’s cold the gearbox speed was moving when engine idle. Not the same speed but it showed drag. I adjusted it to 4.3 and have zero gearbox speed and tested it on Friday but still a problem. On Sunday I kept adjusting it 4.4, then 4.5, where it is into a point it slipped a lot during take off and still after a 30 min drive it won’t go to reverse. Any other ideas?
