1998 dodge: trans...check engine light..speed sensor malfunction…

Customer Question
I have a 1998 dodge...
I have a 1998 dodge ram truck 1500 auto. trans. I went to smog it and the check engine light is on...It had a code And it said that the speed sensor malfunction. So should I just change it is there a way to test it? If the transmission is low on fluid or dirty would that make it malfunction.

Thanks,
Bill

That is a very common code and if you dont have any wiring damage at the sensor I would just replace it. this sensor sells for about 26 dollars and just screws into the drivers side of the trans and is easy to replace.
