Not sure if this is the right section to post in, but im getting ready to swap from a t56 to th350. Can't find much info on the tech side of it and having a little trouble navigating the site to find what I need. I know I need the trans, converter, trans cooler/lines, dipstick, crossmember with T/a relocation, and flex plate. But what has to be done to make it work? I saw in one thread somebody said you have to bypass the neutral safety switch? Is this true and what else needs to be done? Any parts I'm missing? Thanks for the help in advance!
