I have an interesting situation which has proven extremely difficult to find any possible answers to. My car began by having an ABS/TCS light issue in which it would make the ABS noise but would not actually engage. It is important to note that I had this repaired by replacing the wheel sensor bearings on both wheels. Then the problem returned within about a month. Now I have a problem with my speedometer dropping to zero and then increasing rapidly. At first I did not notice any problems with the car shifting but tonight when I had it out to see how the car acted it began having shifting problems. The speedometer will drop under actual speed and then begin trying to shift from gear to gear. After a while of doing this the car actually just dropped into neutral and would not shift itself out. In response I shifted the car out of drive and into second gear and began shifting through the gears myself. When I did this, the car did not slip any longer but shifted extremely hard. I further noticed a whinning noise similar to that of a bad power steering pump which I have never heard before on the car. I do not think that this problem is actually tranny related (at least I hope not) and am hoping you guys could offer some insight. I feel like it could be the wheel bearing sensor but have also read a little about the transmission output sensor. Any help would be much appreciated as I am trying to get rid of this car.
