Hi everyone I am new to the board so go easy on me. I am a newby to the mod game I have a chevy 1977 4x4 lwb with 4speed automatic. I have been kicking the idea of convering it to a manual tranny for a while now, I cant stand not being able to do my own shifting. But just yesterday I saw something about installing a manual valve body onto the tranny and you can do all the shifting manually minus the clutch. Can someone explain what that's all about and how it works? Would I be shifting manually through all the gears and doing all my (downshifts)? Also how would this be possible because I have the old funky column shifter and bench seat. Would I have to cut a hole in the floor for the shifter,how much of a project is it?? Hey any .02 would be greatly appreciated thanks alot.
