has anyone tried adjusting the bands on their c4 trans? The problem I'm having is when the transmission shifts from 1st to 2nd it seems like it just slipping into 2nd, also from 1st to 2nd seems to be shifting way to early? Also to note I had a clunk before I previously adjusted it like I read before when going into reverse so I adjusted the rear band down to 10in lbs and backed off 3 rotations like I read everywhere else! Also to note I don't have a kick down cable on it but it didn't perform like this before I adjusted the back band. Can anyone help with this? Also I can't remember tot the life of me how many rotations I threaded the screw in originally to at least put it back before I did this, I just need to get the transmission at least shifting back like it should before I made the adjustment

Did you have the modulator valve out or adjust it ? The modulator valve will change the shift if it is adjusted
