Preferred your first answer, sounds way more techySorry gasket
I hate to say it but if you search on google there are loads of threads.How would I find out if it's that ?
Joey not me who has the problem its Hammers, also M's don't have auto boxeswhats your mileage mr-p?
I would be more inclined to check cam inlet sensor first...as its a much cheaper fix than a new auto box..I too have an auto and would be surprised if its failing at anything less than 100k...and hardtop is running at higher mileage than that with no issue's..
might also be worth hooking it up to see if its throwing any codes as there could be at least a couple of other reasons for this..i'm not sure about on our cars and I think it is definitely not the case on pre facelift models but I read somewhere that the transmission is adaptive so you could try a reset as well....?
basically exhaust all other possibilities before facing the prospect of an expensive rebuild or replacement...
good luck and I would be really interested to know what you discover..
