Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.
