The shift kit usually just has a few drill bits & maybe a spring for enlarging seperator plate holes. The reclibration kit has shift kit contents plus large TV & Low/Reverse boost valves, valve springs, servo spring, modulator spring etc.. much more complex and the one you should get.
Tip, don't use the washers on the servo pin or use the tight wound spring on the 1-2 shift valve.
2004R-HD2kit if you plan to stay with TransGo products.
