I have an 89 5.0 and for some reason I grind every time I shift hard from 1st to 2nd, but not if I shift nice and politely. I just replaced the clutch with a King Cobra from Ford Motorsports. The grinding occured before and after the clutch change. I have adjusted the clutch cable so that I am happy with the clutch engagement, but I still have the grinding into second. I can power shift into any other gear and there is no grinding. I also have the Steeda tri-ax shifter for the T-5. Can anyone help me out with this problem?
