I need instructions on how to modify a 400 valve body for a brake. I have a solenoid and have my v/b and trans disassembled.

 

Unless you have a mill, EDM machine, and some mad skills, it ain't gonna happen.

Go buy a valve body ready to go. It's not just a solenoid.

You need a brake valve to replace the modulator valve, and the VB requires milling slots, plugging bores.

You have to make a new seperator plate to re-route fluid.

 

I have the equipment and I have the skills, I need to know what slots need to be milled and what bores to be plugged.

 

Get a hydraulic schematic and figure it out. That's how everyone else does it.

Some bores also have to be sleeved. You're also going to have to make a t/b valve. And don't forget about the direct drum stuff.

 

None of you trans guys willing to give it up? I promise not to tell anyone.
