have a 2003 Dodge Caravan beater. 3.3 Auto 4sd 2wd. couple weeks ago, speedometer starts bouncing around at a complete stop or in park. First couple of miles driven when cold will shift first, second, third. After it warms uo, will stay in one gear, either first or second. Cant go over 45 as it's screaming. I replaced both input and output speed sensors after doing some research. No change at all. What are my chances of getting a bad sensor/sensors?? They are Standard sensors. I did not check voltage at the plugs, but i ASSUME there is because the speedometer does work. But we all know what happens when you assume something. Any Ideas?? Seems to be a pretty common problem from what I've read, that is usually fixed by replacing the above sensors.
