The transmission slips and jerks while driving. I bought the car brand new and have been keeping up with maintenance religiously.

- San Diego , CA, USA

When driving car 25 miles per hour the car stops jerks decelerates the eventually kicks back up some times it does it with normal speed. Which has almost caused several accidents when car suddenly decelerates stops in the flow of traffic then having to wait till it kicks back up or just try to pull off road to keep from getting hit very scary when driving on highway of in rush hour traffic! or putting on flashers at the last minute hoping not to get hit!

Bought the car in 2008 w/ 65,000 miles. Within a few months of purchase noticed very violent upshifts while on the freeway and occasionally the car would slip into neutral while traveling @ 65-70mph (very scary). Took car to dealership while under used car warranty and was told nothing was wrong and it was the way I was driving. We started filing complaints with Ford but they were of no help and they have told us that the trans needs to be replaced. Two years later (@75K miles) the transmission completely failed while driving (very dangerous). Trans and tcm module needs to be replaced (approx: $5000) and not even sure if that will fix the problem.

06 Ford Fusion doesn't shift - I was traveling with my daughter from nv to AZ. After having driven 2 hours I exited the highway, stopped at a stop sign and was able to travel approximately a 100 feet when out of no where the engine revved up to 5000 rpms and stopped moving. The vehicles behind me were caught off guard because of my sudden stop in the middle of the road. I tried pushing the gas pedal to get us to the roadside before being rear-ended. The engine kept revving up and creeping toward the side. I pulled to the side of the road to let the cars behind me pass and waited 5 minutes before deciding I was not going to have my daughter and I in the middle of the night stranded on the side of the road. I pushed the gas pedal and got the car to very slowly accelerate and move without shifting but catching speed. Once the car was moving at 60 mph there weren't any problems, but if I had to slow down or come to a stop the car would take forever to begin catching speed. I was able to get us to a safe place 25 mins away and parked the car until the next day. Because it was a small town and a Saturday there were no mechanics available until Monday. I had to stay the weekend waiting for a mechanic. While waiting I did a google search and discovered the horrifying fact that Ford is fully aware of this issue caused by them purchasing transmissions with faulty valve's. I am a single mother and it is unbelievable to me that Ford can get away with selling a faulty product. I am taking my car to a transmission mechanic that was referred by a friend where I am going to determine if this issue can even be fixed. I only have 10 payments left on the car and am dumbfounded that I might have to spend 1/2 of what I owe on the car to fix a problem that Ford caused. What does it take to get a recall like they did with the 2010 Fusion?

Car slips out of gear and fails to shift out of neutral for acceleration.

- Santa Rosa, CA, USA

I was driving on a highway at 65 miles per hour when all of sudden my car just started slipping out of gear. I have 70,000 miles on my car and it started with about 63,000 miles. I was just recently at a 2 way stop with the non stop being a highway of 64 miles per house in South Dakota. I stopped and seen no cars coming and starting going across the intersection and my car wouldn't go into gear. I sat in the middle of the intersection trying to get it to go and finally after about 15 seconds I got it to run and luckily there was no traffic coming or I would had to get out of my car and run to the side because it wouldn't start going. I don't have the kind of money to go into a repair shop and spend 5000 dollars on a new transmission when I know that is what it is. It occurs probably once a day.

2006 Ford Fusion transmission slips out of gear and slams back into gear at highway speeds. Also clunks into each gear as it is downshifting.

- Fort Wayne, IN, USA

Transmission will not shift, this is the second time this has happened. The first time we took it to a repair shop and a rebuilt transmission was put in. Then 9000 miles later it happened again.

- Moncks Corner, SC, USA

Automatic transmission sticks when in slow moving, stop and go traffic on the highway. In several cases, I have nearly been hit from behind because the car does not accelerate immediately after putting my foot on the gas pedal and when the car finally does accelerate, there is a strong thump and it feels as if the transmission is going to fall out or as if I had been hit from behind.

- Castro Valley, CA, USA

I have a 2006 Ford Fusion sel with 40,500 miles on it. Have to have transmission valve body replaced, $1800 repair. I've searched on line and found this to me a problem with many, many other Ford Fusion. Contacted Ford office and said there are no safety issues with the car. The tranny "kicked" so hard it brought my 14 year old daughter out of her seat, I do see this as a safety issue. It could cause a me to wreck, because you never know when its going to happen. Still owe 9000 on this car, it's a same us consumers are having to put such money into a vehicle. Ford needs to step up and make this right, this is an ongoing problem with this make of car.

2006 Ford Fusion V6.... my wife was driving on the expressway with my two year daughter in the back seat when the transmission slipped out of gear as if it went into neutral going 60mph. She let off the gas peddle and the transmission engaged. Trying to get back up to speed she stepped on the gas peddle and the car jerked violently and caused it to slow down even more. She was able to get it back up to speed by slightly pushing down on the gas peddle.. after reading all the complaints, how is there not a forced recall!!!! this is extremely dangerous! the 2010 Fusion has a recall for unsafe transmission issues, why not the 2006?

When driven in town car will stall for about 10 to 15 second then jerk forward around speed between 25- 40mph with a sudden increase in speed up to 10mph. When entering highway and merged into traffic. I began speeding up to 60 mph the transmission hesitatedthe stall for 10 seconds then jerked, like it finally shifted but then turn around and stall gain. The car would not respond to the gas pedal and was stuck in 2nd or 3rd gear one of them. I took the car to the dealer several times and the don't know what the problem, this sudden increased in speed is very dangerous during rush hour with traffic I nearly hit the car infront of me, the car stalling is very flighting when entering highway. This can cause a major highway accident.

- Fredericksburg, VA, USA

Entered highway and merged into traffic. Began speeding up to around 55 mph and transmission hesitated and jerked, causing me to slow down to around 45 mph. The car would not respond to the gas pedal being pushed and was stuck in 2nd or 3rd gear. I coasted to the next exit where I exited the highway and drove to a safe place to stop. The trasmission light came on and I had the car checked at a nearby autozone to see if safe to drive. They could not duplicate problem but after stopped and restarting car, it did not happen again and transmission light went out. 63,000 miles on the vehicle...I had my 3 children, all under 5 yrs old with me...definitely a serious safety issue.

2006 Ford Fusion S 2.3 L with 5sp automatic transmission... with less than 20,000 miles I brought my car to a Ford dealer and was told nothing was wrong with the transmission... now I know it sounds huge, but 3 years later hard shifting and sometimes refusing to shift for a car with an msrp of 19800 and 100000 more miles of extremely irritating shifting (clunking) I am up a creek without a paddle for a known faulty transmission. So either I pay on this car for nearly 2 more years for a yard ornament or pay out 4000 to fix it. This is a known and quite common problem. I was told it was normal and nothing was wrong... really? I have had 10 yr old cars with 200,000 miles that shifted better than this car did after 15000 miles. Ridiculous....... Ford knows of this problem and has refused service and replacement due to cost. They knew of this problem 4 years ago and still thousands are paying thousands of dollars to repair a faulty transmission.

While driving my 2006 Ford Fusion SE V6 with 6 speed transmission, the transmission started slipping at 40mph in a snow storm and I almost lost control of my vehicle from the loss in power. It now randomly slips out of gear at all speeds and downshifts hard lurching the car out of the lane.

- Allen Park, MI, USA

When accelerating, merging into traffic, the transmission pops out of gear and the engine will continue to accelerate while the car coasts, and slows. The transmission will eventually engage a lower gear when it has slowed down, but only if you are patient and ignore the urge to accelerate as traffic bears down on you from behind. This is terribly frightening and dangerous as the vehicles which require the most room to stop, usually travel in the same lane one is merging on to. This occurs not only on freeway entrances, but on long uphills and anytime one lets off the throttle and then tries to accelerate again quickly. A diagnostic from an auto repair shop reveals nothing. I have contacted about 30 other same model car owners who describe the same problem. The fortunate few who have been able to get to the root of the problem have said that the defect is in the "valve body". most have this problem after the 50,000 mile mark. Many, like myself, have had this problem for a long time. It is a matter of time before one of us gets rear ended and crash, or worse!

- Chula Vista, CA, USA

My 2006 Ford Fusion transmission started slipping at 34,000 miles. Dealer said there was nothing they could do since my car was made in the first part of 2006, no additional warranties were available. I bought the car under the assumption that there was a warranty still available. Now my transmission is going out, I still owe 11,000 on my car. After talking to alot of Fusion people, this appears to be a very very common problem. It's also very dangerous, the car slips out of gear revs up and then pops back into gear just as you are trying to get into a lane. Very dangerous, I have almost wrecked several times and had to pull over.

- Granville, OH, USA

2006 Ford Fusion failing to shift during acceleration, shifting suddenly and violently, failing to downshift and running extremely high RPM creating very dangerous conditions when passing, merging and slowing. Dealer failed to resolve the issue during 3 separate repair visits 2008 to 2009. Several attempts to reprogram tcm & PCM were unsuccessful. PCM replaced in 2009 but has not resolved the issue. Research indicates that Ford is aware of defective transmission valve body causing the issue but has not done a recall.

- Scranton, PA, USA

The contact owns a 2006 Ford Fusion. While driving approximately between 15-30 mph, the contact stated that the transmission slipped in and out of gear continuously. In addition, the vehicle would jerk violently. The vehicle was taken to an authorized dealer for diagnostic testing. The technician stated that the transmission needed to be replaced. The VIN was not available. The vehicle was not repaired. The failure mileage was approximately 80,000. Updated 01/11/2011

I own a 2006 Ford Fusion SE with the 3.0 V6 engine. At just over 55,000 miles, vehicle would come out of gear while shifting between 30-60mph, roughly 2nd-3rd, or 3rd-4th gear. Vehicle would go into a high rev and not move. After letting off gas, you have to wait 5 seconds for it to "re-engage", then sometimes in a high gear at low speeds causing vehicle to shake violently. This is a very serious and dangerous mechanical flaw with this transmission! it is the aisin transmission used in a variety of Ford, Lincoln, and Mercury vehicles. (2005-2006 Ford five hundred, 2006 Ford Fusion, 2006 Mercury zephyr, 2006 Mercury Milan, 2005-2006 Mercury montego) there are 100's to 1000's of complaints on these and multiple tsb (technical service bulletins) through Ford Motor Company, etc. (tsb 07-26-9, tsb 08-24-1) calling it aisin transmission harsh shifting. Harsh being an easy term to describe this problem. And still no recall on this or compensation from dealer or manufacturer. If your vehicle is out of warranty, you are on your own with this $1,500 plus repair on a defective valve body according to Ford Motor Co. This is a tremendous safety issue especially when needing to merge or accelerate rapidly to get onto a freeway system or overtake and pass on the highway! I guess it will take a serious injury or fatality to cause a law suit for anything to be done except a tsb! with all the documentation and complaints I have seen on these, I hope the manufacturers have a strong legal team! I will never buy a Ford, Lincoln, or Mercury again. And we wonder why americans buy foreign! it is a sad day people, but the truth hurts! our us car makers need to stand behind their products better and improve their business ethics or they will continue to fail and go bankrupt.
