Me and my buddy have been trying to get his transmission back together for about 4.5 hours and we are stuck with one thing. We installed the new clutches in and started sliding everything back in the transmisson. When we got to the piece you put in after the second gear clutch pack and slid it in, it ended up not sliding in flush with the top of the transmission. We can not figure out why the parts won't slide in just a 1/4 inch further.
