When converting my 101 Ambulance to automatic, I had the choice of the usual LR ratios for the transfer box. Before deciding which one, I bought a compleat 2nd hand auto/tranfer unit from a V8 Disco to use for mocking up the necessary brackets and to avoid the core charges on both units. It confirmed that the 1.2 to 1 was too low. So I went for the 1.003 to 1, which the tuned 4.6 pulled fine apart from the occasional motorway incline which needed the gears to be manually pulled into 3rd. When I saw this option, I was VERY interested, and now having had then fitted it really is the perfect ratio for mine. Despite only being 8.8% lower, it pulls much stronger in EVERY gear but without adding too many revs when cruising. It now actually accelerates on the same motorway gradients when asked, without the need to change down. With the engine closer to peak torque at cruising speed (60-65mph), it MIGHT even save some fuel... ????
