Hi All

Whilst i await a call from a dealership, i thought i'd come here to tap into the PH fountain of knowledge!

We have a code P2791 "Gate Select Direction Circuit Low" on a 2006 F430 Coupe with F1 paddleshift. Has anyone had this before and if so what was the issue?

Car starts and works fine, then randomly throws the code (after 10 mins of driving this morning for examples), bleeps, then won't go above second gear in auto or paddleshift mode. Shutting off the car, leaving for 10 mins or so, and re-starting clears it, but it does come back.

Any ideas!?

Many thanks, Mark

Thats guys

Have located the fluid tank back right of the car behind the panel. Is it just a case of unscrewing the cap and checking level? Or does anything have to be done before i take the cap off?

I understand there is a leveller inside which the fluid ideally must be 5mm above, rather than relying on the attached dipstick?

Havent gone to the dealer was simply awaiting a call from them with info.

Hooked the car up with an OBDII reader to get the code. Understandably anything more than a fluid check will need a dealer to take over but a few people have said to check the fluid first.

If thats not low, or if we top up and it doesn't solve, then indeed it'll be booked into a dealer.

Good to know we can use the dipstick, was just checking i didn't need to do anything before removing the cap as its linked to pressure and hydraulics!

Cheers, Mark
