812SF Gearbox issue
Discussion
Oh well, interesting one at the weekend when out for a little tootle.
20 minutes into my drive the car decided to throw a gearbox failure warning, with my instantly losing 1st & 3rd gear. Managed to get it home ok, but fault wouldn’t clear and it was trailered off to my local dealer. Initial investigations and error codes have Ferrari instructing gearbox removal and strip. These things happen I guess; just pleased that it’s still under the four year factory warranty. Can’t imagine this would be a cheap repair. I’ll update next week when I know more if anybody interested.

In the end, this was diagnosed as simply a sensor which had not been sufficiently torqued when the gearbox was built and which had simply loosened over the miles. No parts needed, but a huge labour intensive gearbox removal, strip and reassemble. Biggest wait was for the factory to send over a special jig to support the gearbox during removal. An expensive error by whichever tech was working on the line that day.
Do they use torque paste to mark the components? If so you can tell which tech worked on it by the colour code, even if it’s not clear from the build record.
That’s poor quality control. (Honda in their NSX assembly line use digital torque wrenches that electronically log the torque of every component on each car!)
