Automatic Transmission problems of the 2004 Mercury Mountaineer

This vehicle is has a power train problem from day one with the 5r55s/w transmission and awd transfer case. I purchased this vehicle where it stranded my family over 200 miles from home and it's a non running car. This vehicle should have been removed from being sold with this defect and crushed! I will never buy a foundonroad dead Ford pos ever. The transmission went into neutral with out any notice. To repair the faulty drive train I will cost me aprox $2400. 00 mileage 152,000 third time the drive train has been worked on. . There tranmissions were failing in a little as 50,000 miles.

2004 Mercury Mountaineer v8, 47,000 miles. Transmission is shot. It slipped in and out or reverse (creating a very dangerous situation since I could not control the vehicle when it was in reverse) and it struggled to shift gears in drive. No warning light before the problems began. The vehicle aged out of warranty in July 2010. Ford will not pay for anything (although the dealer is cutting me a break on the service costs).

The contact owns a 2004 Mercury Mountaineer. The contact noticed that when driving, the transmission was unable to be shifted into second or fifth gear. The vehicle was taken to an authorized dealer who informed the contact that the transmission needed to be replaced. The contact called the manufacturer who took a complaint but offered no further assistance. The failure mileage was approximately 131,000.

The contact owns a 2004 Mercury Mountaineer. The contact stated that the vehicle began to experience a very hard shift when changing gears and driving any speed. The vehicle would also surge forward slightly during the hard shifts. The vehicle was taken to an authorized dealer where they were unable to diagnose the failure. The contact also stated that the gear shift lever felt abnormally loose whenever operated. The vehicle was not repaired. The failure mileage was 68,000 and the current mileage was 71,000. Updated 3/7/11 updated 03/14/11.

Transmission rebuild at 100,000 miles, 6 yrs old. Feel like it is too soon to have this kind of problem. I understand this has been a quite a common problem too. The body panel under the back glass is also cracked.

2004 Mercury Mountaineer sometimes jerk really hard when put in reverse gear. Twice, it jerked so hard, I had to slam on the brakes, cause it was backing back fast. Really scared me. Other times, it jerks hard, but stays put until I press the gas. I never know when this will happen, there is no warning. Took truck to Mercury dealer once, over a year ago. Said they checked, but couldn't find anything. Vehicle is paid for. No longer have warranty. About 3 weeks ago when the last jerk occurred.

Here is the e-mail I sent to Ford regarding what is going on. : my name is leanne freeman I own a 2004 Mercury Mountaineer,I have been having transmission trouble with the car since I bought it. I am concerned that I am not the only person having this trouble I looked on the internet and was able to find 25,000 pages of people having the same trouble many of which have made contact with Ford. I am concerned that Ford knows there is a problem and has done nothing to fix it. . Read more...

During the later part of June 2008, I purchased a 2004 Mercury Mountaineer from carmax at the chicago ridge location in illinois which had 28,579 miles. According to the carfax report and sales person, this vehicle had successfully passed the 100 point inspection, and under normal driving condition this car had no major mechanical or electrical defects. Within the first 30 days I noticed a slight delay between shifting gears began to manifest, so naturally, I took the car immediately back to carmax. Since the problem exceeded their ability to fix it, I was instructed by carmax to take the car back to its original manufacturer, which is your organization, Ford. On July 1st 2008 a Ford mechanic at the 95th western location reported that they reprogrammed the truck, replaced vibration damper, and worked on the pulley-crankshaft. The delay ceased for a short period of time. Within the next few months, the problem reappeared in an even greater capacity than before as now the gears between the forward and reverse proceeded to produce a kick back motion. I decided to get a second written mechanical opinion from meineke transmission and muffler on 107th western, only to be told that the transmission was bad. Since the 100 point inspection on the carfax did not indicate such, as I would like to believe that carmax would not have sold me the car in that condition, I decided to get yet another written opinion. Once again, by another independent mechanic at luchas auto repair in south chicago, I was told that not only was the transmission bad but that it had to have been that way upon my original purchase as the year of the car (2004) is not commensurate with the degree of damage to the transmission as the car is less than six years old. Let me also state that the car is also under 50,000 miles.

The contact owns a 2004 Mercury Mountaineer. While the vehicle was turned off, the contact's two year old son grabbed the key and placed it in the ignition. He attempted to start the vehicle, but the engine never ignited. The child then proceeded to place the shifter in either neutral or drive and the vehicle began to roll approximately 350 feet down a hill. The vehicle crashed into a brush-hog and a Honda vehicle before finally coming to a stop when it crashed into a building. The child sustained a contusion and lacerations to his head, chest, and legs. The vehicle was towed and is currently at a salvage yard. The police stated that even though the vehicle was not started, the gears were able to be shifted, which should not have occurred. A police report was filed. The contact believes that the failure was due to a manufacturer defect and they should be held accountable. The speed was unknown. The current and failure mileages were 59,000.

Transmission delay and then slamming into gear, sometimes causing the vehicle to lunge forward or backward.

When backing up will hesitate and then fly backwards. Feel of delay in transmission when have come to a stop and going from one gear to next. Is increasing getting worse.

Vehicle jerks into reverse. Vehicle was placed in shop to have additive placed in transmission fluid to correct the problem. The problem has not abated. The transmission is also very loose. After being placed in park it lunges 3 to 4 inches in the direction of the slope it is parked on.

Transmission - no overdrive.

While shifting into reverse transmission hesitated three to four minutes before engaging. Then, vehicle shook. Driver drove vehicleto the dealer, and mechanic determined that transmission needed to be replaced.

2004 Mercury Mountaineer, v8, automatic, awd. VIN du86w84zj23248, purchased August 2004. Current mileage is 22000. Mid December 2004 I started experiencing odd or rough shifts going from 2nd to 3rd. It started happening occasionally then it became more constant. I also experienced harsh reverses, one was hard enough that my husband said it could give you whip lash! what was ironic about the whole thing was I was going to make an appointment with my local garage when I got a letter from Ford (January 2005) indicating a problem with the transmission fluid which might cause a harsh reverse. So I took it to a Ford garage january1 5,2005, and they installed the additives. I drove the truck about 2 weeks after that and didn't feel it fixed the problem. I took it back to the garage and this time they said they reconfigured the computer. After I picked it up and drove it for a week or so, it wasn't any better. I'm taking it back to the garage again because it still has the problem. This problem is a lot like your other complaints especially #10103034. I think this is a problem that Ford should look into before it causes an accident especially those owners that drive in winter weather.

My 2004 Mercury Mountaineer shifts rough, lunging forward with a hard shift, and sometimes dragging. Also, when shifting from park to reverse experience a very hard clunk followed by a thrust backwards.

I purchased a 2004 Mercury Mountaineer v6 in April, 2004. I immediately started to notice a harsh jerk when putting the car in reverse and sometimes while driving forward. It sometimes felt like driving a 5-speed vehicle. In late September, 04 while backing out of my driveway, me and my 13 yr old daughter experienced a very harsh jerk as if someone had slammed in the back of the car. We were both shaken. I started to experience neck problems. I made my first dr. Appt. In early to mid October 2004 and was told that my vertabre was out of place. When the recall notice came in February 2005 (I believe) to me, I took my car to be repaired and I was told that it would take at least 4 hours to fix. It actually took the dealship 3 days to fix it. The auto technician told me that my car was worse off than others that he'd seen before with the same problem and additonal parts had to be ordered. My car is working okay now that it has been fixed. On the other hand, I have been to the doctor several times with this neck injury. I have had x-rays, mri and ultra sound completed. The jerking of my vehicle has caused injury to the #2 vertabre in my neck. I experience head aches, severe neck pain, and shoulder and back pain. I have been to physical therapy- recommended by my doctor and to the chiropractor. I have a very hard time sleeping and working due to this pain. I called Ford motor company to alarm them of my injury due to the defective transmission in the vehicle that they manufactured. The individual that I spoke with was very rude, non- caring of my injury and spoke to me in a negative tone. I was told that there were no medical provisions on this particular recall. To this day, I am still in constant pain. I have suffered long enough and I feel that it is time for Ford motor company to own up to the rresponsibility that their defective vehicle has caused an injury.

Problems with transmission in my 2004 Mercury Mountaineer. When in park and shifting in reverse it delays and then a loud hard clunk. It also clunks from going into second gear. My car is out of the standard 36,000 miles/ 3 year warranty. I am very disappoint in Ford. The car hasn't even hit 30,000 miles yet.

Consumer stated that when starting vehicle and placing it in reverse vehicle hesitated, then jumped into gear. Also, vehicle sometimes jumped into gear when placing it in drive, but not as bad as placing it in reverse. Consumer called dealer and manufacturer and was told that they were aware of the problem, but it was not a recall. Consumer was not involved in a collision because of this malfunction but was afraid that one day he may.
