Better yet, drain your tranny, drop the pan, change the filter, and re-fill with new fluid....till it runs out. I don't buy all this alternator stuff. Hell, if that's it, put it on a trickle charger over-nite and drive off! I think you are fixing the tranny through the cabin filter!~
I hear what you are saying, as it is still unexplained why jacking the car up reengaged the drivetrain. One would THINK that if fluid was the problem, we would have seen signs of leakage under the car/in the driveway or garage, but I have seen none. I probably will go ahead and do this just for good measure anyway. However, that still wouldnt explain my alternator voltage fluctuating between 11.5 to 13.8. As I understand it, the voltage should remain fairly constant around the 13.8 to 14.0 range, maybe a bit lower with accessories running. When my battery is disconnected and the car is running, my idle is very rough and the lights flicker like something out of a poltergeist movie.
