Well, My car grinds real bad going into second if you rev it over 2 1/2 grand in rpms. My clutch has been real stiff every since i got my car. My cousin drove my car who also has a mustang gt, and said he thinks the grinding going into second is because the clutch is bad. But the guy i bought it off of said he thought the syncro was going out of second. Every 5 speed i have drove has a real smooth clutch and mine is real stiff. I was wondering if this could be my problem instead of the syncro. My car is susposed to go into the shop monday for the syncro but i have doubts that is the problem. Help would be needed.
