I didn't experience slow shifts - the issue I was/am dealing with is when is shifts under acceleration, it feels like the front end is going to break off. It slams into gear so hard that it shakes the steering wheel. The only way I can get to where it doesn't do this is if I accelerate hard enough that it shifts into 3rd at about 55 and into OD at about 70 or so. It's the final shift that is the worst.
<<Root is the PCS so yes... but, by putting in the shift kit, you limit the movement in the accumulator and do not trigger the max adapt code >>
Bill made this comment above earlier - Is the max adapt code that which causes this harsh shift condition?
