hey, i just finished a nv4500 swap in my 2001 dodge 2500 i rebuilt the transmission with an updated mainshaft and all new bearings and synchros, when i shift into 4th gear it is real loud chatter till it get to about 35mph to 40mph what could cause this i dont have the correct shift boot on it so it lets in some noise but it doesnt sound right, thanks

I put an updated shaft in it and the 3rd and 4th sychronizer hub slid on it wasn't a press fit could that cause it?
