Question about 2003 Mercury Sable
2003 Mercury Sable Transmission Problem The car was in motion when the transmission disengaged and the car started to coast. The transmission will not engage into any gear, regardless of the shift lever position. I can move the shifter without any problem. The car just had the tranny rebuilt less than 1500 miles ago. This same thing happened about a month ago, got the car back last week from the first incident, have not had it a week, been driven less than two hundred miles and the problem reoccurs. The last time it happened, I was told the problem was not the tranmission rebuild; but, rather an electronic part that is external to the transmission which contols shifting. Replaced it and it ran fine for almost a week. Any assistance is appreciated

SOURCE: Transmission hesitates shifting into second and perhaps third gear when driving slow. When acceleration is positive transmission shifts smoothly. Reference "99 Mercury Transmission" as Subject when
Several things could be causing your problem:
p.s. If you have the fluid changed, make sure it's done from the tranmission pan, not through the filler tube; siphoning through the filler tube can be hazardous to the transmission, especially cars with a lot of miles

When was the transmission rebuilt and was it done by a shop with a warranty? I have yet to see an alternator cause damage to a transmission but there has been stranger things. If the alternator was hooked up wrong or a wire was left off, the system could be loosing power to one of the ECMS. Or one of the ecms could of been damage if the wrong battery terminal was hooked up. That I have seen. For the moment, it sounds like the car is in limp home, which is a safety feature by the manufactures that does not allow the car to be driven. Are there any lights on, check engine light, transmission light ect when the car is running?

SOURCE: Car wont move.
Could be that your linkage is broken and just looks like it is shifting or a bad tranny module or tranny but i would look at the linkage and see if it is hooked up to the tranny.

I have a 2003 Mercury Sable as well - my transmission went out with only 52,000 miles. I checked with Ford company and they do not have any recalls on the transmission, however I think it odd that you had the same problem with the same model with in the past 6 months.

ONe thing to check is that your throttle position sensor (TPS) is working as it should and that the electrical connections to it are clean and tight and that wires associated with it are intact. When your TPS starts misbehaving by sending the wrong position values to the ECU then erratic engine revs and associated difficulty in gear changes follow. TPS is a an electrical sensor mounted on the outside of the throttle body on the end of the throttle plate shaft. As the throttle is opened the shaft rotates. The amount of throttle (shaft rotation) is measured by a contact within the TPS sliding on a carbon track. The TPS has three electrical lines to it. One is at consistent low voltage ('throttle closed' end of the track) the other is about 5 volts ('throttle fully open' end of the track) and the third is the variable sliding contact which sends a voltage corresponding to the throttle position to the ECU. The TPS is pretty easy to check out with a voltmeter and you can read the variable out put by simply turning the throttle shaft by pulling on the accelerator cable. If the TPS needs replacing it is a pretty cheap and easy to do. Hope that helps some
