Re: rough gearbox?
In both my A6 and my Crossfire I always shift to second and then first, even with the car completely stopped. Otherwise I find a direct shift from neutral to first to be a little sticky. By first shifting into second, I almost always have an easy slide into first.
I will admit the A6 shifts smoothly from 1st to 2nd while the Crossfire is sticky. It took me about 25k miles to finally find the spot where it slides into 2nd somewhat easily. But it still catches occasionally. I keep hoping that when I get above 30k miles it will be better broken in and shift more smoothly.
