Thanks so much, it is an AX4S. Saying that link might help was quite an understatement. It made it into a 10 minute part swap, instead of an all day hunt for the VSS. The Haynes manual is wrong as it says to jack up the car and pull it from underneath. For anyone else doing this it is an easy job through the hood:The link in the quote refers to this topic.
You have an AX4S. This might help:
1- reach in with the left hand while standing at the right fender. Feel for the VSS just below the #2 cylinder. It is on TOP of the transmission. You may need to pull back a heat shield.
2- Pull of the electrical connector. Remove the 10mm bolt with a box / open end combo wrench.
3- The VSS pulls straight out toward the driver's side.
4- The new VSS pushes straight in toward the passenger side. Bolt it. Plug it. Drive it.
thanks for the info and pics, but for some reason I STILL can't find the VSS on my 99 Sable DOHC. I studied the pics carefully and went all over the area near the passenger side half-shaft on over to below Cylinder #2, but can't feel or see anything on top of the transmission that looks remotely like a VSS.
There is a sensor in a different place, mounted vertically but not on the transmission itself, but that doesn't seem to add up with what I'm reading here.
I'd rate my abilities as at least intermediate, and sadly spend well over 45 minutes looking and feeling for the stupid thing. Is it possible there's some kind of variation on where they put these things? Has anyone else run into this as well?
