Ford Fusion Transmission Problems & Cost | 6F35 | AWF21 | FNR5

Designed to replace the midsize Ford Taurus, the first generation Fusion could be had with  a 160-hp 2.3L 4-cyl, or a 221-hp 3.0L V6. The smaller engine could be paired with either the Mazda G5M 5-speed manual, or the Mazda FNR5 5-speed automatic. V6 models were fitted exclusively with the AWF21 / Aisin TF-80 6-speed automatic. A 2010 facelift brought a host of improvements, including a new 175-hp 2.5L 4-cyl, a 240-hp version of the Duratec 3.0L V6, and the new Ford 6F35 6-speed automatic. Fusion Hybrid models used an Aisin CVT. The second generation Ford Fusion was part of the new One-Ford global product strategy, which meant this one car could be sold in all markets. North American versions were powered by a number of different engines, including turbo 4-cylinder’s, a hybrid, a plug-in hybrid, and a V6. The 1.6L EcoBoost model was available with the Ford B6 6-speed manual, the other engines were paired with the 6F35 6-speed auto, the hybrids got the Ford HF35 CVT transmission, while the V6-powered Ford Fusion Sport got the 6F55. Something seems wrong with your Fusion? Let’s look at some of the most common Ford Fusion transmission problems, and see what you can do to get your car back on the road.

Ford Fusion Transmission Recalls

2014-2015 Fusion – Unexpected Vehicle Roll Away – 14V736000 / 14C11

Summary
On November 18, 2014, Ford recalled 2014-2015 Ford Fusion models that were manufactured between July 27, 2013 – October 31, 2014, 2015 Ford Fusion Hybrid models that were manufactured between February 24, 2014 – October 31, 2014, and 2015 Ford Fusion Energi models that were manufactured between July 14, 2014 – October 31, 2014. These vehicles can exhibit a condition where the ignition key could be removed, even though the gear shift lever isn’t in the Park position.

Consequence
If the gear selector isn’t in Park, removing the ignition key and exiting the vehicle could result in the Fusion rolling away, potentially causing physical injury and property damage.

Remedy
So solve the problem, Ford dealers were instructed to reprogram the Instrument Panel Display Cluster. Owners can contact Ford at 1-866-436-7332 (refer to Fusion recall 14C11). Or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 14V736000). This recall began on Issued November 18, 2014

2010 Fusion – Vehicle May Roll Without Warning – 10V222000 / 10C12

Summary
According to the recall, some 19 vehicles left the factory without the park rod guide retention pin being installed properly. This could prevent the park prawl from engaging Park.

Consequence
With the transmission unable to engage Park, the vehicle could roll away and cause serious physical injury or property damage.

Remedy
Ford notified owners on May 28, 2010, and dealers were instructed to inspect and install a new park rod guide retention pin. Owners can contact Ford at 1-866-436-7332 (refer to Ford Fusion recall 10C12). Or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 10V222000).

Problem – Some vehicles built before 9/2/2006 may exhibit a noticeable transmission whine during light throttle applications at speeds between 40 – 60 mph.
Solution – Install a mass damper kit on the transmission shift cable near the bulkhead in the engine compartment (part #6E5Z-7L256A)

TSB 10-22-4 – AWD vehicles – Shudder/chatter/vibration on turns or a thump/clunk noise on light acceleration – AF21 Transmission
2010 Ford Fusion – 2010 Ford Taurus – 2010 Ford Edge – 2010 Ford Flex – 2010 Mercury Milan – 2010 Lincoln MKS – 2010 Lincoln MKZ – 2010 Lincoln MKT – 2010 Lincoln MKX
Problem – Certain vehicles built between 10/1/2009-12/31/2009, equipped with all-wheel-drive, may experience a shutter or vibration in the driveline during a tight turn. They may also experience a thump or clunk noise during light acceleration. These symptoms may also occur under 40 mph (64 km/h), when driving uphill or towing under heavy acceleration.
Solution – Installing a properly remanufactured PTU (Power Transfer Unit— a simplified transfer case) may solve this problem.

TSB 10-22-4 – AWD vehicles – Shudder/chatter/vibration on turns or thump/clunk noise on light acceleration – 6F Transmission
2010 Ford Fusion – 2010 Ford Taurus – 2010 Ford Edge – 2010 Ford Flex – 2010 Mercury Milan – 2010 Lincoln MKS – 2010 Lincoln MKZ – 2010 Lincoln MKT – 2010 Lincoln MKX
Problem – Certain vehicles built between 10/1/2009-12/31/2009 equipped with all-wheel-drive, may experience a shutter or vibration in the driveline during a tight turn. They may also experience a thump or clunk noise during light acceleration. These symptoms may also occur under 40 mph (64 KM/H), when driving uphill or towing under heavy acceleration.
Solution – Installing a properly remanufactured PTU (Power Transfer Unit— a simplified transfer case) may solve this problem.

TSB 11-12-10 – Sluggish acceleration from 0-5 mph (0-8 km/h) followed by harsh bump or slip on takeoff – 6F35 Transmission & 6F50 Transmission
2010 – 2011 Ford Taurus – 2009 – 2011 Ford Edge – 2009 – 2011 Ford Flex – 2011 Ford Explorer – 2010 – 2011 Lincoln MKS – 2009 – 2011 Lincoln MKX – 2010 – 2011 Lincoln MKT
Problem – Some vehicles may experience sluggish acceleration or a hesitation feel during a rolling stop, followed by a harsh bump or slip feeling. This can be caused by a design flaw in the 6F35 valve body / 6F50 valve body.
Solution – On transmissions originally built for Mercon LV transmission fluid (listed on the dipstick), the valve body will have to be modified by deleting one hole in the valve body separator plate, and removing the check ball in the area of the deleted hole. If this modification is not performed properly, the transmission may experience a loss of reverse or a 2-3 shift flare.

TSB 15-0047 / 17-2219 – Push button start – Shift to Park or Transmission Not In Park message – discharged battery – unable to remove key
2011 – 2017 Ford Edge – 2011 – 2017 Ford Explorer – 2011 – 2017 Ford Flex – 2011 – 2017 Ford Police Interceptor Sedan – 2011 – 2017 Ford Taurus – 2011 – 2016 Lincoln MKS – 2011 – 2017 Lincoln MKT – 2011 – 2015 Lincoln MKX
Problem – Vehicles equipped with a floor shift selector lever and push button start, may display a ‘Shift To Park’ or ‘Transmission Not In Park’ message, even though the transmission is actually in Park. It may also not be possible to remove the transmitter key, and the battery may discharge due to the warning message remaining illuminated.
Solution – Install new park detect switch

TSB 10-21-2 / 10-17-4 – Slipping, 5th gear starts from stop, PRNDL display error, backup camera on while vehicle is in Drive – 6F50 Transmission & 6F55 Transmission
2009 – 2011 Ford Taurus – 2009 – 2011 Ford Edge – 2009 – 2011 Ford Flex – 2009 – 2011 Lincoln MKS – 2009 – 2011 Lincoln MKT – 2009 – 2011 Lincoln MKX
Problem – Certain vehicles may intermittently experience slipping, 5th gear starts from a stop, the electronic PRNDL display may flash errors, and the backup camera may be on while the vehicle is in Drive.
Solution – Install new Ford transmission range sensor / TR sensor.

2013-2014 Ford Fusion – TSB 374584

Problem:
On Ford Fusions equipped with either the 1.5L or 1.6L, fluid can accumulate around the bottom of the transmission housing. Sticky, “honey colored” fluid is likely from excessive grease or rust-inhibitor that was applied during manufacturing. Less viscous fluid is likely to be engine oil, or automatic transmission fluid.
Solution:
If the fluid is determined to be grease or rust inhibitor, it can simply be drained, and the housing cleaned with brake cleaner. If the fluid is determined to be engine oil or ATF, further diagnostic procedures may be required.

2013-2014 Ford Fusion Hybrid / Ford Fusion Energi – TSB 14-0176 / 387601

Problem:
On Ford Fusion Hybrid models equipped with the Ford HF35 transmission, owners may experience a pronounced thumping, rubbing, or grinding noise coming from the transmission.
Solution:
This problem can be solved by replacing either the entire transmission, or the transfer shaft gear assembly. The transmission cooling system will also need to be flushed.

2010-2014 Ford Fusion – TSB 15-0079 / 379414

Problem:
Owners of some 2010-2014 Ford Fusion models equipped with the Ford 6F35 transmission, may experience a fluid leak coming from the left half shaft seal, due to premature wear to the transmission case bushing.
Solution:
To solve this issue, an updated case bushing, seal and half shaft will need to be installed.

Solenoid Failure

One of the most common Ford Fusion transmission problems is a failed solenoid. These little plunger like devices are used by the computer to route pressurized transmission fluid and change gears. To activate one of the solenoids, the computer sends an electrical charge though a coil of wire that wraps around the plunger mechanism. Heat and vibration can cause these wires to short out, which will lead to all sorts of transmission problems.

If you want to check the functionality of your solenoids, simply hook an ohmmeter to the two wires coming off of the solenoid. The reading should be somewhere between 20-30 ohms. If you get a reading above or below that number, it’s a safe bet that solenoid won’t function properly.

Can I drive with a Ford Fusion transmission problem?

If your Ford Fusion can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

How often does a Ford Fusion transmission need to be replaced?

The overall lifespan of a Ford Fusion transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Ford Fusion transmission last for between 80,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Ford Fusion transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Ford Fusion transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Ford Fusion transmission replaced?

In order to replace your Ford Fusion transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Ford Fusion Transmission Problems

Solution A: Buy a Used Ford Fusion Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Ford Fusion Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Ford Fusion Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

2013 Ford Fusion SE 2.5L, bought it used, long story short check engine light came on, 2 codes: p0751 A and P2700. Taken it to 3 places, all of which are telling me the nothing except I need a new transmission. This may very well be the case, however when the car loss power upon accelerating and was able to make it home I added transmission fluid after 2 quarts of that and 2 quarts of Lucas Transmission additive the vehicle would start to engage in drive after putting the car in reverse. No leaks, unable to get under to view the fluid level but all three places I’ve taken it to have yet to look at the fluid, suggested not to drain the fluid and then another said the drive piston was broken “assuming.” How the trans had not enough fluid would be from the dealership I got it from, but that’s a different issue. Any advice? I feel if I dont try the small stuff first, this could be a huge waste of money if other steps were not completed first, however I’m not made of money and I’m either going to dumb the same amount into a different vehicle or this ford. I’m open to any response/advice.

Have a 2010 Fusion 2.5L with 257,000 miles and it runs like new! Would like a newer one but will not even consider an ecoboost engine! Those who say that the 2.5L is low on power are wrong. I get 29 mpg combined city and highway. Ford has lost my business with offering only ecoboost engines!.

I have a 06 fusion, I noticed delayed shifting. I took it to be looked at, I truly wanted a second opinion. There was no trouble codes found, noticed shifting issues in passing maneuver in Temps above 212. The repair quote was excessive.

I have a 06 Fusion 2.3L manual 5-speed. At 140,000+ miles I had the clutch and lower motor mount replaced. Now after the mount was replaced… The shifter isn’t operating correctly and I was told that the shifter needed repaired as it likely was broken down inside.
Ford has discontinued the rebuild kit I was told. And finding one has been a hunt!!!
I was wondering if one for a Mazda could be used?
I loved driving it!!!!!!!
It just needs a better set-up than the factory plastic one. I also was checking going aftermarket and using a sport short throw shifter.
