Hi
On my way home yesterday (60 mile freeflowing A&B roads, doing normal speeds with no significant stop/starting) I stopped off and had to do a three point turn and then park up. While I was maneuvering and reversing the car it jumped from R to 1. At first I thought I must have knocked the paddles but then when I had parked up I had to wriggle the car back a bit and every time I selected R and applied power the car jumped to 1st and even 2nd on one occasion. The road was ever so slightly up hill but I wouldn't call it a hill or even much of a slope.
Anyway I left the car, picked up what I needed to pick up which took about 15 minutes and drove home. Once safely back on my drive I tested reverse a few times and all was good. This morning the car was fine for the school run and I tested reversing up a a slight incline and it all worked fine. I've just scanned the car and the only fault codes relating to the gearbox were P1770 - Gear engagements with wrong shifts and P1772 - Opposite gear engagement.
2011 4.7 MC, 67K miles, clutch is 11K miles @ 38% wear (as of last month), major service 6000 miles ago, no clutch slippage when driving, no oil on driveway.
If its not just a random Maserati glitch then I have a feeling its hydraulic oil quantity, condition or temperature related. If it was one of the F1 system valves then wouldn't the failure be more consistent? Has anyone else experienced this and found the cause?
Cheers
