Maybe The Way Your Clutch Is Adjusted, I Just Read In One Of My Mustang Mags A Quick Way To Tell If Your Clutch Is Adjusted Properly Is. Let The Clutch Out In Nuetral (if You Can) Wait A Bout Ten To Fifteen Sec Then Push The Clutch In Count To Nine And Go Directly For Reverse If It Grinds Its Not Adjusted Right. Dont Know If Thats The Prob But May Help?
