I've had my 99 Fourtrack for a couple of months now with no problems. It's got 60K on the clock, and a full service book. Whilst driving today (steady 75 in fifth on the M3) it twice jumped from 2H into neutral, in about 10 miles. I managed to get the 35 miles home at 55 without a re-occurence. There were no nastey noises or anything, it just 'fell out' of gear. The transfer box seems to be working fine otherwise (I hadn't used it much to the point), and the main gearbox seems to be problem free. Has anyone got any ideas what's going wrong?
