about a Tranny kit

[Nacho-RT74]

I found a MOPAR NOS tranny kit with only this part number or name or identification or whatever you call on box:

SK-TF(4)

is this the Stock one or maybe a little bit performance one ? what can I expect about this ?

SK-TF is a TransGo kit, commonly called the No-Yo-Yo kit it is intended to rectify a torque converter fill problem.

There is little performance improvement, for this you would want the TF-1 or TF-2 reprogramming kit (these also include the parts in the SK-TF kit).
