Mike best advice I can give you is to pay close attention to all snap rings and make sure you note if they are flat or concaved and make sure you get them in the right side up,and coat all o-rings with stp to help from not cutting them when installing,make sure all clutch packs are within tolerance after putting together,and make sure all parts are super clean,one small shaving or piece of grit will ruin your whole job,clean the valve body super clean with brake clean and make sure no valves are sticking,and when you put it together make sure all bolts are torqued properly,it is important--hope this helps you out and good luck ,you might want to check on a shift kit for better shift performance, it helps a lot and makes the shifts more positive,they cost around 60 to 80 bucks depending on what you want
