Here is your UNbiased opinion from me... The Intense and Thrasher kits are the only thing I suggest to people not building there trans and want a good kit. Both are very complete kits and include upgraded springs which do help, and the Intense one includes a new gasket plate for the accumulator body. Scuffing the accumulator bores with scotchbrite is a good idea though I think those kits include sandpaper, either way it has been a rebuilders tip for years to do on any transmission and here is why... With a smooth bore there is nowhere for the fluid to sit and this can cause the accumulator pistons to stick or get cocked in the bore which can not only cause irratic shift feel but also cause the center hole for the pin in the acc piston to wear out and cause more pressure problems. Scuffing the bore surface gives the fluid somwhere to stay and keeps the bore lubed up to prevent the seal from dragging and causing the piston to stick. And before you ask since everyone else does lol, I use Transgo shift kits in all of my builds BUT as they come in the kit they will NOT produce firm shifts and I use the kits as a base to work in conjunction with other internal changes which can only be made when the trans is apart. So in a nutshell, my top picks have and will continue to favor the Thrasher OR Intense kits as they are the most complete.
