Bigdon,
My kit was form a tranny supplier on Ebay. IT came with springs, and gaskets and some stuff you don't use unless your doing a complete rebuild...
Three things, 1 Buy a new valve body gasket from first FIRST, I don not recommend re using the old one..
Second, There a pack of springs that you do not use unless your doing a complete rebuild
Third, DO not use the wire that jumps the EPC solenoid, I recommend doing the EPC pressure adjustment only..
Search "5R55E" on Ebay and you will find the kit...
