Performance Automotive & Transmission Center is who I am asking about. Has anyone done business with them and was it good or bad? I am looking at getting a tranny from them. http://www.transmissioncenter.net/200-4R.htm At the bottom of the page is a chart and the one I am leaning toward is the level 4. Is this a good tranny and does it have the good stuff in it? The guys there SEEM to be knowledgable and honest. I would like to do things locally in case there is a warranty issue.
