6F50 / 6F35 Applications and Compatibility:

The Ford 6F50 / 6F35 transmission first saw production in 2007 models. The transmission fits both two-and all-wheel-drive vehicles.

The first application of the technology is in the 2007 Ford Edge and Lincoln MKX crossover SUVs. Ford claims the 6F50 is designed to handle 300 hp (224 kW) and 280 ft·lbf (380 N·m), while General Motors rates their 6T70 variant to 315 hp (235 kW) and 280 lb·ft (380 N·m), the 6T75 to 315 hp (235 kW) and 300 lb·ft (407 N·m), and the 6T80 to 410 hp (306 kW) and 369 lb·ft (500 N·m).

Ford 6F35 / 6F50 / 6F55 DTCs

Ford 6F35 / 6F50 / 6F55 Technical Service Bulletins | TSBs

TSB 10-22-4 – AWD vehicles – Shudder/chatter/vibration on turns or thump/clunk noise on light acceleration – 6F35 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.

Common Problems with the 6F50 / 6F35

Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement: Some of the most common 6F50 / 6F35 transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the 6F50 / 6F35 transmission engages Drive or Reverse. There are a number of design flaws in this transmission, and any one of them could be causing these symptoms.

Another common problem is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.

Updates to Remanufactured 6F50 / 6F35 Transmissions

• Torque converter support bearing fully inspected to prevent sleeve failure.
• Completely remanufactured pump, including polishing of pump rotor mating surfaces, provides consistent internal pressures and helps eliminate pressure-related issues.
• Remanufactured and tested valve body to improve shifting, lubrication, and performance.
• Transmission Control Module (TCM) tested for proper function of pressure control solenoids, shift solenoids, and pressure switches.
• Clutch clearances set to custom-spec standards for improved shift feel and timing.
• Bushings and machined surfaces polished to a mirror-like OE finish of 15 RA or less.
• Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
• All new, bushings installed in key locations to improve internal fluid flow control and fluid pressures.
• Complete system correction and recalibration kit installed to address several OE flaws. Modifications include updates to servos, the PR system, and valve body accumulators.
• Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.

How to Buy a Remanufactured 6F50 / 6F35 Transmission

1) Buying Locally

When you go to your local repair shop, they’ll order a remanufactured 6F50 / 6F35 transmission, then mark up the price. So at the end of the day, you’ll be paying 15% to 30% more than the actual cost of the unit.

2) Buying Online

Buying a reman transmission through a company like Street Smart Transmission will save you a considerable amount of money because you pay the wholesale price (avoiding a repair shop’s 15% to 30% markup), they’ll ship the unit to the shop of your choice free of charge, and returning your old transmission is free as well. Then all you have to pay for is the labor to install the unit (usually $400 to $800), and you’re on your way.

How Does it Work?

To order a remanufactured 6F50 / 6F35 transmission from a company like Street Smart Transmission, all you need to do is provide your vehicle’s VIN number, the mileage, and the address of the repair shop that you want it shipped to.

Financing

Replacing a transmission can be expensive, so Street Smart Transmission offers financing through PayPal Credit. Depending on your credit, you’ll be able to order a new transmission, get back on the road, then pay for it over time. You may have to pay labor charges for the installation up front, but you won’t have to shell out for the transmission all at once.

Shipping Charge/Location

When it comes to shipping, a transmission is quite heavy. So you’re going to pay quite a bit of money, unless the reman transmission company offers free shipping. Street Smart offers free shipping to a business address, which is usually the repair shop that you’ve chosen to install the unit.

What is a Core Charge (Core Deposit)?

Every remanufactured transmission originally came from somebody else’s car. Therefore, they need your broken transmission in order to refurbish it for another customer.

Your old/damaged transmission is called a “core”, and many companies will collect a core charge (usually $500 to $1500), which will be refunded once they receive your old transmission. (Street Smart does not charge an up-front core charge.) Make sure to ask any company for their core return policy, so you’ll know what to expect.

Our Recommendation

We recommend Street Smart Transmission. We have found Street Smart to be of the highest quality. Their transmissions carry a 3 year / unlimited miles warranty that covers both parts and labor. Their warranty is nationwide and attached to the VIN so it is transferable with ownership if you decide to sell the vehicle. It also covers both parts and labor for the installation of the replacement transmission.

Finding a Shop to Install the Remanufactured Transmission

If your transmission has failed, you’re going to need a skilled mechanic to replace it. You can find a shop to install your transmission using our shop locator map.

For warranty purposes, you need to find a reliable repair shop. That way, if the replacement transmission doesn’t work properly, the warranty will cover it.
