    cheetah R.P.M.V.B. reverse boost delete mod.

    Has anyone done this mod to a cheetah rpmvb? Id be nice to keep current foward gears line psi & tone down the reverse line psi. Its pushing 300+ in reverse. Waaaay to much & will kill the car somtimes. Forward is about spot on 120-130. It involves blocking a hole in the seperator plate & knocking down a wall in the upper casting of v.b. by the press regulator valve. Thanks fellas.

    There is an easy way to accomplish this by simply drilling one bleed hole, It is all spelled out in the Knowledge section above (with photos) Look under drivetrain-3speed trans.

    Yep I wasn't sure about the reverse boost delete mod. But I knew the bleed mod worked. Drilled a .039 hole in the upper casting & i knocked l.p. adjusment screw all the way flush. & woorked pretty good( just like it did in my own transmission). Kept fwd l.p. of 120-125 & knocked down reverse psi to 230-240 psi @ idle. I may my just use my extra cheetah R.P.M.V.B. as a lab rat to see if the reverse boost delete works without any other side effects.
