I am going to try replacing the VSS on my 99 Taurus, 3.0 DOHC its the AX4N tranny. Hoping this will solve my hard 1/2 shift problem. Am I correct that it the drivers side, above the drive shaft? I think I found it, looks like 3 to 4 wires plug in on top, slide clip. Just want to be sure what I am looking at. Also what is the best way to get to this to replace. Have the part on order. Thanks.
Hello and good day to you:
First may I ask have you gotten a Repair Manual for the Vechicle??? Like a Chiltons, or a Haynes...???
First here is a good couple of good Links:
Replacing VSS - Ford Forums
1999 Taurus 24V DOHC - Speedometer failure- VSS replacement - Mombu the Ford Forum
The VSS is located rear center of engine compartment on the trans axle.
To replace the VSS, raise the vehicle, remove the Y pipe, remove the VSS
heat shield, disconnect the VSS wiring harness, remove the VSS retaining
bolt and remove the VSS from the trans axle. You will know you have the
correct sensor by the color of the wires in the harness connector, they are
gry/blk and pnk/org
You WON'T reach it from up
top. You have to unhook the exhaust from the Y-pipe, drop the cradle, and reach over
the trans to get to it. You'll have to remove a heat shroud (foil covered fiberglas)
and kinda feel your way around. There is a bolt with a 10mm head next to the sensor
that has to be removed, then it "should" pull right out. I've run in to some 1997-98s
where the VSS was really stuck in place. The trans needed to be removed to extract
them, due to a little bit of corrosion. Good luck.
