Cheap doesn't make it with this sort of thing.

Had a customer recently buy a very expensive 200-4R then put a "shelf" converter from one of the big "box stores" in it. It grenaded the converter on the first test drive and lunched the transmission pumping it FULL of ground up needle bearings and hunks of busted up sprag material. It also voided the warranty on it you he was left with a big pile of bovine excrement that he had to pay to have completely torn down and repaired on his nickel.

WAY back in the early 1990's I built a 4L60 for my 1967 Impala SS and bought a cheap converter for it. I loved that swap over the PG that was in the car, until I raced a Rustang away from a traffic light and lunched the converter on the 2-3 upshift. Same deal, it DESTROYED the transmission pumping it FULL of ground up material from the converter. I completely rebuilt the transmission again having to replace most of the bushings and many other items then bought a high end converter (switched to non-LU) from Precision Industries. It not only worked a LOT better than the POS shelf unit I bought the first time I went on to put over 30,000 pretty hard miles on it and it never grumbled once.

You don' t have to get a second mortgage for a 200-4R converter but for sure I'd go with a reputable company and avoid any of that bottom of the barrel crap........FWIW.....
