I have a 2000 mercury mountaineer that started having transmission problems at 70k miles. It has an aod transmission and it wouldn't shift into gear when I would hit the gas to drive. I took it into the dealer I bought the SUV from and they told me that I was low on transmission fluid and that was the problem so I had them fill the fluid. Almost immediately it started going through fluid and at around 85k miles it slowly started having the shifting problems again. Now it hardly shift at all. I did some research and it sounds like there is a major defect in the 2000's transmissions for both the mercury mountaineer and ford explorers. I truly believe that ford should be issuing a recall and fix the problem. There have many times where I was merging into oncoming traffic only to have my transmission fail to engage and I've almost been broadsided by the oncoming car. Here is a website that talks about the transmission failures: http://www.carcomplaints.com/mercury/mountaineer/2002/transmission/transmission_failure.shtml please check it out and help us get the problem fixed.

2000 mercury mountaineer transmission failure vehicle has only 64,000 miles, transmission has been power flushed by our local ford dealership with no correction, we were told the problem was shift flare, with the o/d light flashing is common with all 5r55e transmissions with 4.0l v6 engines. We were told it would be best to replace the transmission with a factory remanufactured unit, rather than try to repair the old transmission at a cost of $2500.00 to $3000.00 dollars. We are now to a point where we cannot drive the vehicle any great distance other than right around town. Assistance from ford would be greatly appreciated this vehicle is the fourth ford product we have owned, we now have doubts about our 2005 f150 4x4 supercrew we use to pull our 26' travel trailer approx 4860lbs. Our vehicle is in wonderful condition and we do not want to get rid of it, the manufacture needs to step up and help all the loyal ford owners that have believed in there products for many years.

Just bought a used 2000 mercury mountaineer and this morning we experienced a problem with the transmission. Put it into reverse and it immediately shut down and started to roll backwards because of being on a slight incline. Put it back into park and tried again to have it happen again and again. Looked up on google and now find that this seems to be an inherited problem that ford is not addressing. What is our recourse on this matter?
