The Transgo shift kit comes with a handful of parts but should not be used with the intended purpose of making firmer shifts because it really isnt going to do what you want it to. It includes new 1-2, 2-3, and 4th accumulator springs, a new redesigned boost valve and spring for the valve body, and a few new seals that go inside the trans. I use these kits as a base kit for my builds but there is more to it than just what comes in the kit but you cant make the other changes that I make unless the trans is apart. The best complete kit comparable to the Transgo kits that I use but also are made for selectable firmer shifts are the Intense kits and the original Thrasher / Transgo kits.
