grinding T3650

When I shift into 3rd, unless I baby it in it grinds. If first started out when I would shift hard...like i said, now its a lot. What could be wrong? Is it my synchro? If its bad hopefully I can put the stock shifter back on and take it in for warranty. Thanks for any help!
 
I had this happen to mine as well. It started grinding like a Mo Fo one night as I was leaving the track...oops... Wouldnt grind if i babied it, but even in "normal" shifts it would.

Took it in to Ford with the Tri-Ax in place and they overhauled the tranny without a word to me about mods. It was the 3rd gear synchro by the way. Guess I got lucky! :nice:
 
i'm curious, is there a synchro for reverse too? cause i have been having the grind in reverse really badly and i might have to take my tri ax off and put the stocker back on to take it in :(
