I have a 99 1500 5.2 4wd, with 175xxx miles on it. It just started acting funny. I would go to take off from a stop light and it lacked alot of power that it had before. After driving for a little while the o/d off light would come on and stay on. I would hit the button on the shifter and it wouldn't go off. It feels like it takes longer to shift. Even downshifting, I would let off the gas and it would stay in that gear. Does anybody have a clue what this could be? Other than that it runs good. I'm gonna drop it off at Aamco later on this week hopefully. Thanks!

 

Are the rpms above 2500 At 65?
