Freshly rebuilt T160, no discernible damage to the gearbox when I fitted it, but have to confess I wasn't looking very closely. If I'm just cruising it goes up the gearbox just fine, but if I'm trying to do a quick shift I sometimes miss 3rd gear. Similarly, on down-changes when dropping from 4th to 3rd I sometimes get a false neutral, most times it then drops into 3rd of its own accord. It never jumps out of gear, just sometimes doesn't like going into 3rd. Any ideas?
