1997 Buick Lesabre V8 Front Wheel Drive Automatic 108, 00 miles
My parents bought me this car and we have had more problems than some. I am asking for your help because at this point we don't know what else to do. To make a very long story short, we have replaced the motor, the sensors and many other parts. However, there is still another problem. When you are driving up a steep hill, the car wants to go to chug because it does not want to shift down out of overdrive in these steep hills. The fluid and filter have both been changed in the transmission. The car shifts into overdrive at 45 mph on a level surface which seems to be a low speed for this to happen. On the level pavement and the car is in overdrive, you can push the accelorator all the way down and it will not shift down into a lower gear (4 gear) until it hits passing gear. If I touch the brake, the car will downshift out of overdrive, but shortly after the break is released the car shifts back into overdrive and the problem continues. The check engine light has not come on. The car is at about 1500 rmps and 52/53 mph going up the hill.
