Ok background: old school SBC 350 With 2 piece rear main seal connected to a 1996 t56 installed in a 1972 c10 short box
I used the 153 t billet steel conversion flywheel neutral balance for use with the t56 pull style clutch from American Powertrain, New science friction stage 2 mean street Kevlar clutch kit with new High clamp load pull style pressure plate new pull style release bearing and stainless pilot bearing.
New master, slave and stainless line (bench bled several times with vacuum and gravity) NO AIR in hydraulic s. Problem is truck moves slightly forward going to 1st and you have to turn engine off to go to reverse. Clutch won't disengage!!!!! ANY HELP would be greatly appreciated as I have bled hydro system numerous times. Lost as to what to do!

 

Thats the exact same problem i have w my 95 camaro. Was ur old pilot bearing worn way oversize?
