"Planning" on or starting to put together the tranny today. You know how that goes though! Anyway been looking at the difference in the synchros. The one that came out of my A type tranny is the smooth one in the pic. The other is an original that came out of the TR4 tranny and my J type had that design too. When I rebuilt the J type last year and purchased new ones they were like that too. So which is better? I think the ones with the channels were designed to get more oil into them. However centrifugal force you would think would throw the oil out through the channels. The smooth ones would hold the oil in but the synchro is suppose to grab the taper on the gear and the oil would make them want to slip. Can or should I cut or file a channel in the smooth ones or leave well enough alone?
