i just put my new hd tranny in my 250r, in third gear it make a grinding noise, when i put it in all the gears looked fine, everything is torqued to specs, but it will not drive in third gear, 4th through 6th are fine as well as 1st and 2nd. any ideas? my first thought was the tranny bolt vibrating out but i douced it in loctite and torqued it perfectly, trying to figure it out before i open it up AGAIN!!! ARGHGG
