My first D1 was 95 5-speed. Was great until downshifting one night - BAM - no fifth gear. As I was working at an independent LR shop at the time and we had an almost new ZF auto box there, we converted it to auto. Left the ECU for the manual in and it actually seemed to get a wee bit better mileage. The D1 had 440,000 km on it when it went to its next owner, engine only ever had valve cover gaskets and valley gasket replaced. Oh, and two vacuum advances. Both times I discovered they were gone when we hit the trails where it was much more noticeable and really, much more necessary. Always confused people when you lifted the hood and saw an auto trans dipstick and a clutch slave cylinder.
