All I can say is it works great! I used to have issues shifting especially 3rd and reverse. I drained the trans and filled it with Cobra Valley Ultra Shift and it made a huge difference. No more notch or rough shifting. I have a TKO600 trans. I know it's critical to fill them up to the proper level 1/2" below the opening if I remember correctly. Maybe that's part of the problem? Ultra Shift is all I'll use.
