This LRO reader emailed LRO.email@example.com to ask Andrew Varrall about a Discovery 2 gearbox that won't go into low range.
My 2000 Disco 2 automatic 4.0 V8’s transfer box won’t go into low range unless I switch the engine off, then put it into low box and restart the engine. It won’t budge if I go through the correct procedure of foot brake on, handbrake on, and go into neutral.
Also, like every Disco 2 with twin sunroofs, it leaked like a sieve. So I removed the headlining and all the plastic trim, then got my partner to stand on a step ladder and put the hose on it for ten minutes. No water came in, so I took it to a car wash and there was still nothing. However, before this, if it rained water poured in through the seat belt openings and the front light in the headlining, and down the screen pillars. If I reversed off a slope, it would pour in through the rearmost headrests. Now nothing is coming in. I’m baffled. I’ve bought new sunroof seals and three tubes of the sealant used by windscreen fitters. The drain tube connections are sealed perfectly, but I will reseal them because of the work I’ve done so far.

The problem with the transfer box will either be poor adjustment of the cable or a loose grub screw on the inside of the transfer box. The reason why you can select either range when the engine is off is because that requires less effort. Either way, you need to remove the centre console and the sealing rubbers beneath it to gain good access.
You can then try adjusting the cable. If this fails, remove the plate that the hi/low lever attaches to and inspect the selector linkages for damage.
As for the sunroof leak, did your partner spray over both sunroofs and also try around the roof bars, alpine lights and gutters? If so, and there is now no water coming in, then it really is a mystery – but I definitely recommend leaving it alone while it’s no longer leaking!
