The shift kit softens the firm SyTy shifts.
this should explain most of it for you. the syty trans was the most badass thing gm could come up with when these trucks were produced. ANYTHING like a shift will ruin and make worse the trans you have.
NON of the shift kits shift as hard as the stock syty does with the proper timing required to prevent bindup and not too hard that it begins to break hard parts.
So, in review, a shift kit in a syty trans is a step backwards and some of them require you to drill the seperator plate and some ask you to drill molest the VB(which is no longer available thus adding to the value)
