Certain 5-speed auto equipped 2002 models built before 03-04-2002, may experience slipping on the 2-3 shift, or a loss of 3rd gear altogether. This problem is most likely due to a broken intermediate band, which could trigger diagnostic trouble codes: P0733 and P0745
To properly fix this problem, you’ll need to replace both the intermediate and OD bands, along with the pistons. The direct clutch drum should also be inspected for damage.

TSB 06-25-10 – Shifter requires manual override to get the vehicle out of Park – 6R60 Transmission & 5R55S Transmission
2006 – 2007 Ford Explorer – 2007 Ford Explorer Sport Trac – 2006 – 2007 Mercury Mountaineer
Problem – Some vehicles may experience an intermittent condition where the shifter gets stuck in the Park position, requiring the use of the manual override function to shifted out of Park. This transmission problem may be caused by chemicals from the shifter lubricants corroding the shifter switch contacts.
Solution – If no electrical problems are found, a new transmission selector lever will need to be installed.

TSB 07-6-3 – DTCs related to the Mechatronic assembly – with or without the wrench light on – 6R60 Transmission
2006 – 2007 Ford Explorer – 2007 Ford Explorer Sport Trac – 2007 Ford Expedition – 2006 – 2007 Mercury Mountaineer

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

2013 TSB 365099 / 13-5-31
Problem:According to the Technical Service Bulletin: “Some 2013 Explorer vehicles equipped with 3.5L GTDI (twin-turbo EcoBoost 3.5L) engines may exhibit long crank-to-start times and delayed/harsh downshift when commanded in the middle of a 4-5 or 3-5 upshift and delayed upshifts from 3rd, 4th or 5th gear when transmission fluid temperature is below 21 degrees Celsius (70 degrees Fahrenheit).”
To fix the problem, a Ford dealer will need to update the Powertrain Control Module (PCM) software.

2013 TSB 365977 / ASI-32216
Certain 2013 Explorers with the 6R35 transmission may experience a fluid leak from the left hand half shaft seal. This is likely due to premature bushing or seal wear, caused by the half shaft surface finish.
Fixing the problem will require the installation of an updated case bushing, seal and half shaft.

Common Ford Explorer Transmission Problems

Solenoid Failure
One of the most common Ford Explorer 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 Explorer transmission problem?

If your Ford Explorer 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 Explorer transmission need to be replaced?

The overall lifespan of a Ford Explorer 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 Explorer 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 Explorer transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Ford Explorer 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 Explorer transmission replaced?

In order to replace your Ford Explorer 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.

How to Solve Ford Explorer Transmission Problems

Solution A: Buy a Used Ford Explorer 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 Explorer 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 Explorer 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.

I have a 2013 explorer with 66,000 miles. Had a roaring sound under the car. Faster I went. Louder the sound. Took to dealership and they said it needed an axle replaced. Got the work done. Two days later same problem. Now they say it is transmission. Said axle problem caused transmission problem. Had my car over 2 weeks and still can’t tell me what is wrong. Any advice or suggestions.


after doing a rebuild, is it normal for the output shaft to only turn counter clockwise , looking at rear, and not clockwise when in neutral? also input shaft won’t slide out through pump once its tightened down.

95 ford explorer slow about changing into 4th gear. Over drive lite flashing do you know how to get codes from transmission without OBD1 scanner ,have OBD2 scanner but it doesn’t have the OBD1 interface cable went to 3 parts places and 1transmission shop and 1 repair shop. Does anyone have a clue?


My 2009 Ford Explorer was fine. Then one day all of sudden it did not want to accelerate. I wrench would appear in the dashboard. I had to pull over and turned it off. I then turned it back up and it would run for a couple of minutes and then the wrench would appear again and the truck would again decelerate. They changed the body throttle and some sensors and still does the same thing. Mechanic can’t find what’s wrong he is now saying it might be the computer. What is a computer? I’m concerned its already been a month since its been with the mechanic.

I have a 2008 Ford Explorer and when I drive it and it gets hot it will break speed down to one mile per hour. And it only does it when the motor gets hot . It has only 75000 miles on it


Hi i have a 2003 explorer sport trac. There is nothing when it goes in reverse…just revving of engine. I am fairly sure the reverse band broke as i heard a noise. Ive tried in 4high and low as well..same thing.

I believe my transmission is a 5r55e. I have found one from a 2007 ranger, both with 4.0l engines.
Will the ranger 5r55e work in my 2003 sport trac?

Toni Schelm

I have a 2006 Ford Explorer 4.o V6 4×4. Wrench light came on and was not shifting from 2nd to 3rd properly. Took go auto store to have it checked. Said it was Solenoid A. Replaced the solenoid block, filter and gasket. Still doing it. Have to get RPM’s up to atleast 3k let off gas and it shifts smoothly into 3rd. Wrench and engine light came on diagnosed again and same solenoid and gear. The rest of gears are perfectly fine and smooth. So is my only option is to replace either the gear or transmission? I do not work as i am waiting on a decision for disability with my many health issues. Trying to fix as cheap as possible as I have already sunk $400 into it and it is still not fixed. Please help!!!! My only transportation.

Bowe Osborn

Did you rest the pcm after you replaced the solenoid pack? If not unhook negative battery terminal and keep the positive on take a wire w a clip and clip the positive to the unhooked negative cable bar metal pat for about 8-10.minutes. then it should rest the first 10 minutes of driving should fix it if it was the solenoid pack

Karen Edwards

I have a 2008 Ford Explorer with 130,000 miles. The “wrench” light appeared in the dash, but before I could get it to a garage to have it checked the transmission died. Really mad Ford makes vehicles with sealed transmissions which force the people to find a garage to check the transmission fluid levels when a simple dipstick would have told me the fluid was down….totally upset. Feel this cost could have been prevented if these companies would go back and make their vehicles driver-friendly!


My 2007 4wd v8 Explorer did not seem to have transmission issues until the PCM software was updated. Now it hard shifts. It seems to be getting worse. Was thinking of putting Lucas in. I had it flushed and a new filter and made no improvement. Problem gets worse when it’s warm.


Never flush your transmission. Only drain and fill. The transmission will need to be replaced shortly after, unfortunately.
