Sorry for the wait...here goes..
The gearbox problem........from the very start Fox's were returning from exercises with worn bands on 2nd predominatly. This was a common pattern, wear was happening too quick for auto adjuster to keep up. We would reset manually inside on those that were not auto adjusting, but still serviceable. Then a mod instruction came through to change the accelerator pump jets and non return valves to eliminate a flat spot when pulling away.
This was why the bands were wearing, as they pulled off, the engine fluffed and drivers were dipping the gear change pedal ( as you would on a clutch ), to get the revs up again, then let the pedal off, consequently the bands were suffering badly.
From memory, and a lot of things have happened since, so not crystal clear, the initial jet and valve change made little difference, and I think there may have been similar mods later on..............then after many years and at a point when the Fox was near the end of service, the problem was solved. It was caused by too much fuel on accelaration giving "bore wash". A new and modified throttle body was available, with new linkage for the acc. pumps, once set up to instructions, it reduced the max volume of fuel on accelaration by 30%. One heck of a difference in performance.
Thats it !
