I have a C-4 that I am having some problems with. (shifting from 1to3 with no 2) checked modulator,fluid,vacume, ect. I re-adjusted the bands (10lbs backed off 1.5 front-3 rear) It seemed to lock up or act like the brakes were on the first time I drove it when it shifted. After that it seemed ok but just shifted very quickly. I don't want to burn up the bands so would it be better to adjust them on the loose side or the tight side?
