96 SLS trouble codes
 

Hi,
I have a 1996 Seville SLS with 85K. I started getting service engine lights. I had the codes read and they were P0716 and P0717. They reset the codes but they soon came back. Now I seem to get (once and a while a service trans message.)
I'm told that these codes are from the speed sensor. What is the speed sensor and is it easily replaced? I gather it's on the trans, somewhere, but can someone please give me more info. Is this usually only a sensor issue or is this a sign of more serious issues?
Any help would be greatly appreciated. I'd like to try to replace it myself if possible.

Welcome, the VSS (Vehicle Speed sensor) just senses the speed of travel. It is just a electronic version of the cable design used in older rigs, just no cable present. It has a tone ring that the sensor itself reads from on the output shaft (but I do not know which side of the transaxle).

I do not have a parts book forthe number of this partthough.
