yeah, thats what i would do. call around to the local cottman or aamco...or even small tranny shops and see if the builder has ever built performance aod's before. make sure the builder is atleast 40 years old and has been doing it a long time. i know the guy who builds are trannys is really good at what he does and would know exactly what to do with the valve body and stuff. a junkyard tranny costs about 75 bucks at the pull-a-part here in town and a rebuild will cost you anywhere from 800-1500 depending on whats needed. obviously all the normal wear items like friction plates and steels will be replaced along with all valve body gaskets and seals, and band. good luck man. stick with edge for your converter. ive never heard anything bad about them
