I am looking for any suggestions on changing out the VSS on a 99 taurus. Corrosion of the bolt into the trans housing makes me feel like I am going to shear off the head of the bolt. Any tips to break this loose without breaking the bolt?\\
If the bolt shears off, you will need to take it to a trans shop for R&R of the trans, not cheap. Ditto if you snap off the plastic gear at the bottom of the VSS inside the trans. I had one stuck in there very hard (the VSS) and I had a trans shop change it for me for $200. R&R can run $600 or more, be careful!
