My 5 speed mazda trany in my 95 F150 is grinding second gear.
if i take off slow and dont let the enging rev high from first gear, i can sift into second easly. If slam into second i.e. light to light racing (love betting those mustangs) it grinds the gear. Also when slowing down i down sift to take off again, say like going around a corrner, it grinds getting it back into second.

i think i know what it is, just hoping for something else, i really dont want to take the trany down again (did right before chrismas for the clutch-master-slave cylnder replacment.)
thanks
chris
