Nice one Brian,I will give it a go,they will just need to take me as they find me

We will

You can get gearbox error from low battery that will put you in a limp mode. Lot more can go crazy too.

Thanks for getting back to me,I put in a proper Bosch battery and it's putting out 13.6 volts at tick over I was just wondering if there's a common fault somewhere on the gearbox loom also transfer box ain't working any help would be great

Sorry it's 14.6 at tick over, just checked the alternator, could the low voltage at the gearbox cause the fail safe to come on going between 3rd and forth it's giving the impression of slipping when you put your foot down but fine all the way up to third,I am getting engine braking coming down the box in Manual kind of want to rule out these voltage problems before pulling the box,the box,after checking has done 25.000 miles since a full recon and brand new TC from LR dealer so of it's the box or the TC I will be very surprised but I've heard all sorts of things about low voltage on these vehicles, sorry to ramble but I'm just looking for info.cheers
