If you get a grind trying to go into first, you have to put the clutch in first
seriously, though I do get this at a stop, where it doesn't want to engage. I think it is just a sweet spot (or, unsweet spot) where the engagement teeth are at just the wrong position. I have learned that when it happens, I can always select second, which moves the gears enough to get into 1st.
(at stop light)
doh!doesn't want to go to first.
(select second, and then first again)
should it be like that? well, it isn't broken, just unrefined. They could have tuned the enagement gear to get first easier, but maybe like Jamie said, they decided to go for longevity.
