Turbo 400 Valvebody Modifications

We take apart the valvebody and modify for manual/automatic functions!

Awesome experimenting too..With all the different mods...

[@kentklassen8397]

So what do you do with the check balls then after you do the modification to valve body and separator plate do you leave the same amount of check balls in or do you leave some out?

[@BrianSwayne]

If it's just a stock rebuild I would leave all of them in.

If my Tranns is stock Can I do this I want harder shifts

[@billpfeifferjr5497]

What is the purpose of removing the spring under the accumulator piston?

[@BrianSwayne]

Makes it shift harder.

[@raulfernandez7035]

Would this work only 2 check balls ?

[@BrianSwayne]

Yes but have to have HD sprag

[@raulfernandez7035]

@@BrianSwayne I do 😎

Top center and middle center.

I have a 4l80e 34 element sprag, I have mine drilled to 3/16. Which check balls should I use?

[@inscoredbz]

Everyone is telling me that 3/16 is to big for the 1-2 shift hole. They recommend 1/8. I want firm shifts, but I don't want to break my sprag. What do you think? Which check balls do you use?

[@BrianSwayne]

Go .110 to .120 and use check balls.
