Turbo 400 question.

[bpman1234]

Why do most of you go for rmvb ? Cant we use a bop 400 trany with a regular valve body?

You would need a mechanical modulator to run under boost.

that's it just the mechanical modulator .? nothing to the valve body?

Valve body calibration is always important. I'm no expert with the autoshift stuff so I can't even give you an opinion but I do know that there are trans brake valve bodies out there that still have the automatic features.
