I bought a Ferrari 612 F1A '04 from a specialist. I love the car. Due to weather I haven't driven it much. I am in week 10 of its 12 week warranty. I have only used the 'd' setting on the gearbox. In the 3 times I have run the car for over an hour, the f1 automatic gearbox can go straight into neutral, usually during town driving when I have pulled away from lights etc between 20 & 30mph. If I flick a paddle it will find a gear usually and resolve things. Does this sound like a major problem? I am loathed to bother the seller if it is a normal thing. I'd really welcome your advice.

Many thanks.
