I've got the same problem with my XR8, the T5 is mega crunchy at times. Put it into first gear, crunches into second, slight crunch into third, nearly always crunches in reverse. But then, once the car is warmed up and has been driven around for about 15mins, almost no crunches at all. Oil?
I adjusted the clutch the first time I heard reverse grind, but didn't fix the problem.
I think the car actually has a stronger pressure plate, or bity-er clutch as the car shudders if you ride the clutch, really doesn't like it. (remember, I only bought the car a couple of weeks ago.) The clutch never slips when you dump it, so it's definately not worn.
What could be causing the gearbox to do crunch when cold? Maybe wrong oil? If it's not the clutch, not the oil, what else could it be?
