C6 Transbrake and Manual Valve Body Mods (Low/Rev Piston) 

In this video Jay Robarge of Broader Performance will explain why you should or should not modify your low and reverse piston in a Ford C6 transmission for use with transbrake and full manual valve bodies. He will also cover proper location and size of air bleed holes.
Just a quick note, Jay stated a fluid is not compressible but meant to say a liquid is not compressible. Fluids are compressible. Air is a fluid. Sorry for the mis wording. He is too lazy to edit or redo the video!
