New DIY 48re. Works great. Shifts great without issue. Did a couple pulls today. Now going down the highway in OD I've got a random hickup happen 3 times, for a split second rpm picks up then goes back to cruising. Kind of like its trying to downshift. Not slipping, doesn't slip at all.
Already have a GM solenoid. Did a transgo shift kit myself, pressures looked good. Still have plastic transducer, think its about to fail.
