My T5 is acting weird. I think the synchros are going out on it. It doesn't ship smoothly, i have to force it in and out of gear, always grinds reverse, only goes into 3rd gear at certain rpms, only up shifts at 3k and below rpms, it also won't go into 2nd or 1st until I am at a dead stop. Any ideas? Also when it's in gear and the clutch is fully pressed in, it will still roll forward slightly. this is happening on a flat surface too.
