There are two combinations of second gear bush and gear. What can happen over time is that the gearbox can be rebuilt with "early" and "late" specification mixed. It is often thought that the later specification must be stronger and Triumph must have made the changes for that reason, technically this is so, but we have found that the dog teeth on the late specification fail much more quickly than the early type did, although the bush part doesn't.
