I have a Transgo and it is great. My only complaint is that it will shift into OD at WOT when the shifter is still in D. I called them and they know about it and have a fix. The new kits probably come with the fix already. I would buy it again if I went back. The only other kit I would get is the Baumann. They know their stuff about AOD's.
