Blocking the 4th Accumulator Circuit - 700R4s and 4L60Es

I quickly show you an easy way to block the 4th accumulator in 700R4s and 4L60Es without the use of check balls. The main reasons you'd want to do this is to eliminate a potential leakage/wear point, which is the inner diameter of the piston as well as quicken the 3-4 upshift. The faster upshift takes a lot of the slop out of it that is there from the factory. Essential for higher stall, HP applications #4l60e , #700R4, #transmission
