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
