My car 2009 mercury mariner premier, has been slipping (tach goes up but my speed does not) since I bought the car 2-3 years ago. There is now about 56,000 miles on the car. It has been a cold winter, and when I start the car and it is cold, I have been seeing a little pool of oil like substance, and when I back up, there is a line of it. It then seems to stabilize and stop. One day I was using the car cold, and the tack went up, but I couldn't go any faster, or upshift. I took it to the garage, and they said: 6f35 transmission - fluid leak - seal - left side halfshaft. The garage pointed out that this is an ongoing problem with my year mercury mariner, and also the fusion, milan, and escape. The garage said there will probably be a recall on this problem. I can make a copy of the bill and send it. This is a dangerous problem, and the wheel could fall off. Please let me know if I can be compensated for this ongoeing problem with my ford mercury mariner, and other ford models.

Had previously had the dealer look into what I thought was issue with transmission and gears slipping back in 2012. They indicated there was a bulletin, which I believe was on a computer issue, and that the tech made some adjustments. That seemed to address the issue for a while. It had been acting up again, and not quite the same as previously, with more stalling out and not accelerating and then suddenly jumping a little. Asked dealer to look into situation again on visit on may 30th. Techs found nothing wrong. Was driving home on interstate on evening of june 7th when it felt like the engine had lost power. I was driving 60 MPH, but I was able to pull off to a wide shoulder area. The orange wrench light came on. I turned off car and let it sit for a couple of minutes. It started up with no problems. I was able to drive it about 45-50 MPH until off interstate and got it to dealership with no additional problems and left it. Waiting to hear outcome from them.

The transmission slipped while driving so I checked the fluid level. Fluid was low so more fluid was added. Two weeks later the fluid was low again. After checking I noticed the fluid leaking from the lines where the lines run into the fluid cooler. Contacted dealer and no recall has been issued.

In february of 2009 (at 41,214 miles), my 2008 mercury mariner started jerking when I was driving and would not accelerate when I gased. I took the car to a ford dealer and they diagnosed it with transmission failure. Since the car was under warranty they performed a "transmission overhaul". Three years later, february 2012, my car started having the same problem again, transmission issues. According to the paperwork, it was noted "transmission/converter slips and transmission fluid leaked". I was reluctantly told by a supervisor at ford headquarters that some 2008 mariners did indeed have transmissions defects but my VIN number was not known to be affected and because it is out of warranty they will not addressed it without me paying $4062. I have called ford headquarters and they would not provide me with any details on the issues with some of the mariners that were recalled. A car that has transmission issues twice within four years sound like there is indeed a major defect issue with the transmission parts but ford is not willing to admit it. I am sure my car (VIN) should have been included. This could have been a safety hazard for my family and I. This car is a lemon and ford was well aware of it but refuse to correct the matter. Ford should do the right thing and resolve the issue that they were well aware of instead of making there customers believe that it is normal for a car to have transmission failure not only once but twice within four years. I will pursue this matter until I am satisfied with the results. Updated ivoq 03/28/12

Transmission cooler leaking fluid causing gear slippage during acceleration. While the vehicle was in drive and the gas pedal pushed it would rev up then slam into gear or not even go into gear at all and stall. Initial research indicated a common factory defect for mercury mariners and ford escapes. Leaking began at 43000 miles, warranty expired at 36000 miles. Advised by dealer repair cost would be $975.00. I was not able to find any recall information on this problem and was basically told sorry it costs so much.

I have been having problems with my 2008 mercury mariner transmission during the winter of 2010 and continuing. When the engine is cold the transmission slips. When I accelerate the engine revs and then slams into gear. Furthermore, while sitting at a stop sign or traffic light with my foot on the brake, the engine will rev up then shift in another gear then when taking off the vehicle slams into gear. On more than one occasion, the vehicle will cut off completely when idling at a traffic light. The revving and engine cutting off is getting worse when the engine is cold or warm.

I have been having problems with my 2008 mercury mariner transmission. When the engine is cold the transmission slips. When I accelerate the engine revs and then slams into gear. Ford refuses to repair the problem under my 5yr/60,000 mile warranty. Although my car has leaked transmission fluid and I have been told my "transmission" cooler needs to be replaced, it is considered an "air conditioning problem" since my compressor will have to be replaced with it, even though my air conditioner works fine. I know that a recall was made on the transmission cooler part in march 2008, but ford customer service told me that my VIN number did not match recalled cars despite having the same problem. Apparently ford has changed the part number on the trans cooler and orders it from a different company, so the part would not be listed under the warranty. Could you please explain exactly why my mariner was not part of the original recall? Nobody at ford customer service or the dealer service manager can explain why my car was not part of the recall or why this defective part is not considered to be an integral part of the transmission. I am shuffled back and forth between these departments.
