I've got a Defender 90 with a 200TDI engine. The gearbox is a bit on the random side! - it is very dificult to find third and then when shifting to 5th it doent want to engage. I also have an early Defender with a n/a diesel and I occasionally have similar trouble shifting to
3rd, but its only very occasional and it has done 225,000 miles!!!Can anyone throw some light on the problem and whether it is an easy fix.
