It seems the Chevy gods have a vendetta against me.
Some times it shifts fine for a short while.other times the Truck isn't downshifting properly..from a dead stop is will take off in second gear or third.. I replaced the brake light switch since I broke the old one changing the hydroboost. (AC Delco..) I was told that has something to do with the down shifting also..new one makes a loud clicking sound sometimes..don't know if that's normal or not. Changed tranny fluid and filter about 15 or 20000 ago..I will mention ( only because of cruise control being on same switch) that occasionally when I turn my wipers on and put them on high then go to turn them off they will not turn off.. another problem occasionaly the turn signals on one side of the truck will flash extremely fast like there's a bad bulb but there isn't a bad bulb. Does it for a short while then it goes away and things go back to normal.. same with the wipers.. again I only mentioned that those two things because the cruise control is hooked into that switch and a switch I believed plugs into the brake light switch which controls downshifting also if I understand correctly.. totally lost on this one
