Im not really sure if its slipping or what..its kind of wierd....if I get on it at like 60...2nd gear range...it will try to downshift but the rpms will be at like 6k and it will still accelerate and then it will finally kick into gear and go down to like 5500 and dhift into 3rd real quick.. could this just be becuase I need to flush the tranny and change the fluid...its a 96 auto gt with 98,000 on the clock...not sure if the fluids ever been changed but it looks brownish
