I went to the drag strip for the first time with the new truck and on my first pass i went to hit 4th gear and i missed just a little, so i put it back into where 4th normaly is and it was like it was neutral. i then shifted to 5th and it was the same way, i tried 6th gear and it was there and acted like nothing was wrong. i got it home and drained the fluid and took the inspection covers off both sides and couldnt see anything wrong with the gears. there was also no metal chunks or shavings in the fluid. im stumped do you think it could just be a shift fork? 1,2,3,6,R all work with out any problems or grinding, any help would be awesome!! :drink
