No slam against PA but you have alternatives. Consider doing the 'Jerry mod' as described in "Transmissions 101" (in the Tech Articles) of tccoa.com. Jerry is a former Ford trans engineer (he is Mr. 4R70W), works for Roush now, and is one of the best tuners in the land. At the very least, read Jerry's articles -- there is a ton of knowledge and experience in them and it's available for our benefit.
(Lentech makes a good valve body for the 4R70W, too, imho).
