gearbox problems

[kellyv8]

i have just purchased a jreg discovery 200tdi manual with a gearbox fault and was wondering if anyone on here could help

it will only drive in difflock engaged and it will not select reverse, it feels as if the gate isnt even there for reverse

any help would be much appreciated ie, is it the main box knackered or the transfer box

Both

The transfer box is likely to be the cause of it only being drivable with diff lock on. Unless of course a prop shaft is missing or diff or drive shaft or drive flange is goosed. If ya drop the props and turn the flanges hard on the diff's and they have play but are solid then it'll be the transfer box. Dont jump into changing the transfer box though as any of the other options are just as likely and cheaper.

The not selecting reverse sounds like an adjustment problem. If ya take the rubbers off and foam at the bottom of the gearstick theres adjusters there. I'm trying to remember if it was this box that you could screw the reversing sensor in too far which would cause it to block. May be worth unscrewing the reverse sensor as well just in case my memory works.
