Punchy Dan:
Old John:
Mine is the GRS, 3 over 3 with splitter.
Not the nicest of things to use, but you get used to it. If I am changing a whole gear when the oil is cold, I can’t move the lever quickly enough to avoid a crunch, as the thick oil will be assisting the synchro to do their work. Once the oil has warmed up, it’s generally ok.I do a quarter mile in low range with my Eaton before attempting high range in a morning either that or wake the neighbour warming her up ,makes you wonder what sort of pain an auto box may suffer from a cold start though ?
Have you got the 16sp synchro Dan?
On the auto shift boxes, I think some of them at least are constant mesh. I’m sure the I shift is.
