Grinding Into Third???
Anytime I shift hard into third it grinds...bad...could it be bad synchros? After a race or twoit will grind into third even with an easy shift. If I push the clutch in then wait to shift it doesn't grind though. Just got a new short throw shifter it seems like it does it more now. Any advice? Does this happen to anyone else? Should I be prepared to buy a new tranny? I heard these ones were good for up to 800 hp though...

what is "these"? the stock one in an 03? thats the 3650 and no, itsrated for360lbs/ft tq. many people are running alot more than that but thats its official rating.
donno about the tranny, sounds like synchro but have you tried putting the old shifter back in by any chance?

You and me have the same problem.. I have a steed tri-ax. It doesn't have anything to do with the shifter. Its the synchros. Mine has been doing it for almost a year, so depending on how hard you run your car you should be ok for awhile.
