Hi.
I have a 2008 2.7 HSE that on kick down (I think that's what its called) says transition fault, parking brake fault and lowers its self and goes into limp mode.
I have put a new battery on, brake sensor, and replaced an EGR valve so far and its still that same.
any help would be very kind.

oh and my mechanic says every time he reads the codes it keeps saying it loses contact with loads of sensors but apart from when im omn the motorway cursing and need to put my foot down it runs fine.
it will even accelerate flat out with no problems

What voltage is the alternator outputting?

Have you checked/replaced the brake bulbs? When was the fuel filter last changed and was it OEM?
