But from what I have figured out about Taurus' they are notorious for this issue - I have seen issues from early to late 90 models. He is wondering if there is a pin or something that could have possibly came loose? Any ideas would be greatly appreciated and helpful. Thank you in advance for some answers. If you need further info on the vehicle, please let me know and I will provide anything that you ask. I just want this fixed. I drive my 3 year old in this vehicle and I am pregnant with a second child and being a female I do not feel safe to drive this vehicle at all. (The transmission obviously doesn't shift correctly because of this and the obvious - I HAVE NO IDEA WHAT SPEED I AM GOING!!) (One Benefit: I have had this car for 5 months and it still has the same mileage on it, LOL). We keep being told it is the speed sensor, but that has been replaced and it is not the issue. PLEASE HELP I AM DESPARATE!!!!!
You sure about the VSS??? The VSS has a small metal shaft (more like a pin) running through it and I've seen it break before. From the way you descried it, you disconnected the cable from the VSS, spun it with a drill and it worked. That eliminates that side of the eqaution. Remove the VSS and look at it. You should find the broken pin.
