4l60e is taken a duece?
Ya, get it read and let us know what code is set.
Same here....it shifts like stock now....gonna call tomorrow. Doesnt shift firm at all now. Not acting up or throwing a code.
For sure get the codes ran and see what is throwing the light. It could be any number of things worst case that damn weak ass tranny GM decided to put in a truck. Get it checked ASAP before it gets worse.
