trans kit which one

The reason I mentioned W.I.T., is others on this site have used them and seemed to have no issues with the company. For myself, getting transmission parts was never a problem as I worked for a transmission parts supply company. Companies like Cope, A&A, TCI, just repackage parts in their own packaging. I had this discussion once with a guy that had bought an expensive transmission rebuild kit from one of the well known race transmission outfits. Inside where Raybestos waffle lined friction plates, steel plates, all nicely shrunk to a board with their company logo on it. The gasket overhaul kit was in a bag again with the logo on it, but the componets inside were from Trans-Tec. Nothing wrong with the kit for sure, except for the cost because it came from one of the "big players" in the performance transmission industry.
Shopping around various sites will tell you what the average part cost is, and who is over charging. Using a company who cuts costs by employing people who seem to have issues identifying the correct parts is a problem for me.
I tried them out twice. I don't use them anymore.
