So I've got a GSR trans that until recently was going into all gears without any difficulty whatsoever, and had no grinds. Recently it was getting difficult to find reverse, and when I was able to get it, it would be difficult to get out of it. 5th gear shifts fine. Doing some research on here, I have seen suggestions on disconnecting the linkage and manually putting it in reverse. How would I do that? Or is this more likely something internal involving the 5/R gearset?
