hello everyone we have a 03 sable and my wife loves it and wont own anything else, it has started to act like i wont stay in gear when pullin a steep hill, or using near full throttle or in over drive, the rpms go up and down from 2000-4500 and the car looses speed during this letting off the throttle stops this and the fluid is good and and is not burnt and was serviced about 20000 miles ago and no lights come on, will be getting it checked out at autozone to see what the scanner will say, but other than that not sure what to do except take it to amcco and here in town they are a good shop and the dealers use them alot
