So how it started: I was driving home from work and I was on the interstate. I had cruise control on and my car seemed to be struggling in shifting gears. So I turned off the cruise drive and kept driving. All of a sudden my speedometered zero'd out and the odometer stopped moving. I could not use curise drive. I stopped on the side of the road and restarted, it did not work. As I moved foward in my automatic car I noticed it was having problems shifting gears. In fact it will not get pass second gear. I can feel it going into first with a pull and second with a pull but it will not go any further.
Fail safe mode should give you third and reverse
fault in the TCU or a soleniod failure

The alternator light flickering, especially at higher rpm's, is a sign the brushes in the alternator are worn. Normally, the whole alternator is replaced. The alternator is located in a very unhandy place to work on, so its not a pleasant job for a do-it-yourselfer. I had the Mercury dealer replace mine with a rebuilt alternator a year ago, and the cost ran around $500. If the problem is just the alternator, there should be no need to replace the battery, unless it happens to be bad also.

Sounds like you might have lost the tranny,or at least the shift solinoids inside the tranny.

The Vehicle Speed Sensor located on the Transmission is malfunctioning or the connection is malfunctioning.
It is very easily removed and replaced.
The Vehicle Speed Sensor sends vital information for the Transmission to properly Shift. Because yours is malfunctioning, this lack of information is causing shifting problems.
I do not know if you have a Mechanical or Electrical (Gauges or Digital) Instrument Display. I also do not know if you have a 17 or 19 bolt transmission pan, nor what type of transmission you have (AX4N or AX4S) Nor if you have a Speedometer Cable (Mechanical Instrument will have Gauges=Cable).
The best thing to do is to check the connections of the Vehicle Speed Sensor. Unplug and check both sides of the connection for corrosion/oxidation. You can also take this sensor out of the transmission and clean the interior end; reinstall and recheck operation.
If this does not fix the problem, then remove and replace this snsor.
Take the Sensor with you to the auto parts store to compare the part you receive. You should know what tansmission you have and the number of bolts on the transmission pan, and whether you have an Electronic (Digital) Instrument Panel or Mechanical (Gauges) Instrument Panel on your dash.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!
SOURCE: how to change my timing belt for a 97 mecury
There are so many steps. After removing everything so you can get to the timing belt you need to make sure you have the engine set so the #1 Cylinder is TDC. Remove the old belt and re-install the new one. If you need step by step directions on how to do any of this I recommend you get the Haynes Repair Manual for your vehicle since it will show you those and give you instructions on how to make sure your at TDC. If you try putting that belt on without being set to TDC the engine is not going to run correctly.
