Hi - I've just joined the forum so that I be around like minded Disco lovers plus I need some advice from someone more experienced than me. I've had a 97 disco for 3 years and it's been fab, I've had loads of fun in it but recently decided to upgrade to something that smells less like a farm yard and doesn't leak so much. Fed up of having to scrape the inside of the windows as well as the outside! I've been to look at an 04 landmark discovery but the gear box if confusing me. My 97 has diff lock which I use in light snow and ice but the landmark only has high and low range. I looked in the manual and it explains how to get diff lox (push gear lever left when in H or L) but it doesn't feel like there's a gate there. Have they done away with the option of manually selecting diff lock? If so, why does the manual still give instructions to select it and what do I use on slippery surfaces instead? Any help would be appreciated xxx
