I just had 1-2nd gear synchronizers put in my t56. I drove the car over 200 miles and no issues. I was in 1st and went to grab 2nd and all was there was a bunch of noise! I had 1st gear until a certain rpm then it was like the trans was in neutral. Could this be the input shaft from1st to 2nd? Need help Thanks!!

 

Does it get stuck in any gear? will it move in any gear?

 

It doesn't get stuck in gear, it can be hard to get thru the gears though.
