Well i havent seen any articles and i havent seen any prices. But i imagine that someone somewhere will try it sooner or later. I just picked up a 4L80 real cheap and i have yet to see what kinda shape its in. But one day in a wheelin daze i pondered the idea? Now i know the index diamater on the output side is diffrent between the two, is there a way to get a tail shat to mate to a 203 and then just build the adapter between them? Ill let you guys ponder this idea because im sure someone has done it allready. Im all ears guys............... JD (aka-MtnGuy75) Get in, Sit down, Shut up and Hang on!
