Automatic Transmission problems of the 2006 Mercury Mountaineer

The contact owns a 2006 Mercury Mountaineer. The contact stated that the vehicle would lunge backwards when driving in reverse. The vehicle was taken to the dealer but the dealer was unable to diagnose the cause of failure. The manufacturer was not notified of the issue. The vehicle was not repaired. The failure mileage was 52,000 and the current mileage was 55,000.

2006 Mercury Mountaineer v8 awd--when shifting from park to drive or reverse it "clunks" hard into gear. The wrench symbol and the engine symbol light up. The vehicle also drives hard as if it isn't changing gears. The dealership will only say that the Ford TSB recommends replacing the transmission fluid and filter, then resealing with foam seal first but refuses to give me an actual diagnosis of what is going on with the car. They can not tell me the real problem and insist that we will have to work through the various steps on the Ford tsbs which may or may not work (by their own admission) and the cost of final repairs is completely open ended. When I questioned what we would try next after the transmission fluid/filter replacement (because I was skeptical about this causing the issue on a vehicle with only 43,000 miles) they had no answers at all. We have owned this vehicle less than a year. An internet search reveals that this is a major ongoing problem with this model but Ford refuses to own up to it. There needs to be a recall.

2006 Mercury Mountaineer shifts hard when going into reverse, and is also starting to shift hard from 2nd to 3rd gear. Have heard from many there people with 2006 Ford explorers that there is a manufacturer defect in the transmission. Have had chip reprogrammed at dealership (was charged) and also had transmission flushed and it is actually worse now. My Mountaineer has 58,000 miles on this and has been doing this for the past 2,000 miles. Ford should fix this issue.

My truck has 115,000 miles on it, transmission is now gone. When I put it in reverse it would jerk back like the it was being hit, all of sudden it started dragging while driving, and having problems shifting into gear, and now its totally gone. . . Only had the vehicle two years.

V8 Mountaineer jolts when you come to stop, feels like it has been rear ended, no accidents at this point, but there has been a few close calls.

2006 Mercury Mountaineer transmission problems. Hesitation, funny shifting. Could get someone in trouble by the random shifting problem. Ford dealer I went to said they had never heard of the problem. When you google this it is a problem thanks.

My car has had a continuing problem with the transmission. It shifts roughly and lurches when beginning to move. For example, when stopped at a stoplight, and then beginning to drive, it will lurch, jolting the passengers. Our driveway is sloped toward the street. When I park the car, I always set the emergency brake as well. The car always rolls a few inches before the brakes lock, even though it is stopped and in park. On Sep. 4, 2009, my mother borrowed my car to go to lunch. She couldn't find the emergency brake release. She put the car in park and got out to locate the emergency brake. She found it and released it. The car popped into reverse and rolled backwards to the street. The door knocked my mother down and she hit her head hard enough to sustain a closed head injury with minor bleeding in her brain. The car rolled across the street, over the curb and hit a neighbor's poplar tree. The entire tailgate was destroyed, there was some interior damage and the frame was warped. The tailgate had to be replaced, the bumper and trailer hitch had to be repaired and the frame straightened. My mother was in hospital overnight and had to have two CT-scans. She still has headaches and transient dizziness. We are just fortunate the car didn't run her over, hit a pedestrian (there are a lot of walkers in our neighborhood), hit a car or a neighbor's house.

2006 Mercury Mountaineer slipped out of parked in driveway and hit mother inlaws 2005 GMC envoy. This is one of a hand full of times it has slipped off park. Took it to the dealership 3 times and nothing, now I am fighting with grand ledge Ford, grand ledge, mi to get it fix or replace the transmission before someone get seriously hurt or even dies. This is a very scary situation and needs to be recalled as soon as possible.

I have just purchased a used 2006 Mercury Mountaineer awd v8. When the vehicle is coming to a stop, the transmission lunges forward as it is downshifting. It feels just like another vehicle has hit my vehicle from behind. This is a dangerous situation since as the vehicle lunges forward, it could hit a pedestrian in a cross walk or hit another vehicle in front of me.

I own a 2006 Mercury Mountaineer (v8 awd). Everytime I stop the transmission jolts forward as if we have been involved in a rear-end collision. I have called Ford motor company to complain and they have agreed that there is a problem but not to the degree that they would initiate a recall. This is very dangerous and someone is eventually going to get hurt if not killed.

When I stop my tranny kicks and it feels like I got hit in the rear. I took it too fm dealer and they adjusted the comp, but didn't fix the prob. It got worse.

The contact owns a 2006 Mercury Mountaineer. The contact started the vehicle and it immediately stalled. The vehicle was towed to a local dealer and they stated that the entire computer system failed and was replaced. Two months later, the engine light illuminated. She took the vehicle to the dealer and they stated that there was emission failure. The contact also began experiencing failures with the front passenger window and the frame was replaced. The engine light still continued to illuminate and the dealer stated that it was due to the catalytic converter, in addition to the transmission. The dealer did not know how to repair the failures. The current mileage was 1,500 and failure mileage was 411.

Transmission kicks from 2nd gear to 1st gear when coming to a stop. It is intermittent and jarring to the vehicle and passengers. The vehicle was taken in for repair to an authorized dealership. The transmission fluid was changed and the computer was reflashed, however the problem with the shift shock continues.

Bought this Mercury Mountaineer March 2007. Worse vehicle ever owned. Most of the time when stopping I get that thud noise. I feel like I got hit from the behind. When in traffic I worry alot also. I bought this truck in 7 times and problem still occurs. Dealership will not fix it until I show them the problem. I told them it does not happen everyday. With my luck it did not happen when I was there.

I bought my 2006 Mercury Mountaineer April 26, 2006. I started having the transmission problems December 2006. When you put on breaks to stop you hear a thud and the vehicle will actual throw you forward in the seat. It feels like you might not actually stop when it first happens. This happens daily. The fist time I took the vehicle in and left it with them, they drove it and said they did not find anything. January 2007 I took the car back to them and they did dive it and have the same problem. The called Ford and Ford told them there was a recall on it and they needed to put it on the computer and do a recalibrating. They did this and the problem was gone for a week and it returned. I took it back to them and they replaced a part in the transmission, this lasted a week and it started the same thing again. I am now still fussing with them about getting if fixed. They kept it 5 days last week and did nothing to it. I had an appointment with a Ford rep. Last week and this past week and he did not show for either appointment.

I received my vehicle 1/18/2006 a Mercury Mountaineer. On my survey that I returned to Ford in March of 2006, I told them that I hated their " slip-o-matic " transmission. I do not have all the visits documented but the second problem we had was the vehicle would come to a stop at a stop light and then a few seconds later you would feel a "thud" like you were hit from behind by another vehicle. We had the transmission reprogrammed and the valve replaced and that problem seemed to be resolved. But the slipping through the gears continued to be a persistent problem. It is almost as if when you pull out into the highway that you are in suspended animation for 1 to 1. 5 seconds. This is particularly unsettling when crossing several lanes of traffic from a stopped position. . . Like pulling out of a gas station (with the traffic) while a semi is coming up behind you real fast or turning across traffic with out the green arrow and you really have to get across quickly sometimes it works sometimes it doesn't. This occurs randomly but yet approximately 10 to 20 times a week. Right now the SUV is in the service center. I have requested the next repair to be performed via TSB 07-13-8 but the dealer is insisting that I must demonstrate the problem before they will repair it per above mentioned TSB. . . . . . . They took my word before for the reprogramming and the valve replacement but now they do not seem to believe me anymore.
