Recalls & Known F150 Transmission Problems

Recall ID 12C23-S1 – Ford 6R80 Transmission

– Summary
In May 2012, the Ford Motor Company issued a compliance recall on the following vehicles equipped with the 6R80 transmission:

2011 – 2013 Ford F150
2011 – 2013 Ford Expedition
2011 – 2013 Ford Mustang
2011 – 2013 Lincoln Navigator

– Consequence
It seems that a faulty 6R80 transmission range sensor / TRS can cause a number of transmission problems when the shifter is placed in the Reverse position. The symptoms include failure to engage reverse gear, the electronic PRNDL indicator will not display reverse (if equipped), the backup lamps will not function, and intermittent rear video camera operation (if equipped).

– Remedy
Replace the 6R80 transmission lead frame (which includes the TRS sensor). Owners may contact Ford at 1-866-436-7332 or NHTSA at 1-888-327-4236

2012 F-150 Shifter May Be Moved Out of Park Without Pressing the Brake Pedal (NHTSA Recall Number: 11V582000)

Summary
Ford recalled 16,091 units of the 2011 Ford F150, to replace a defective brake shift interlock switch. This little device is designed to prevent the shifter from being moved out of Park unless the brake pedal is depressed.

Consequence
If the brake shift interlock switch isn’t working properly, the shifter will be able to move out of park, without the brake pedal being depressed. Should this happen, the truck could instantly lunge forward or backward, causing an accident with another vehicle or striking a pedestrian walking by (again, that would be very bad).

Remedy
In 2011, Ford instructed its dealers to inspect and replace faulty brake shift interlock switch on affected 2011 F150 models. If you’re experiencing this problem, or are unsure if the recall repair was performed on your truck, you can call Ford Customer Service at 1-866-436-7332. Have your VIN number handy, and refer to this Ford recall campaign number: 11C21

TCC Application in 2nd Gear – 4R75E Transmission / 4R70 Transmission

2005 – 2006 Ford F-150
Problem – A lack of power after the 1-2 shift can be caused by an un-commanded torque converter clutch application / TCC apply. The P0742 and/or P1742 DTCs may also be stored.
Solution – The #7 check ball inside of the valve body may have worn down to an incorrect size, allowing the torque converter clutch to apply after the 1-2 shift. Replacement of this check ball may solve the problem.

Slipping in All Forward Gears – 4R75E Transmission

2005 – 2006 Ford 4R75E Transmission
Problem – Many 2005 – 2006 Ford vehicles equipped with the 4R75E transmission, may experience excessive slipping in all forward gears. Metal shavings may also be present in the transmission fluid.
Solution – Replace forward clutch drum and update ECU with program 06B06

Poor performance with DTCs P0715, P0716 & P0717 – 4R100 Transmission

Problem – Poor engine performance and acceleration may be due to a sticking solenoid regulator valve
Solution – If the solenoid regulator valve cannot be repaired, the valve body will have to be replaced

Ford F-150 Transmission Technical Service Bulletins

TSB 13-4-23 – 4R75E Transmission – Grinding/Slipping/Loss of Reverse

2008 – 2010 Ford F-150
Problem – Some vehicles may experience a grinding/whining noise, unusual vibrations, slipping, and potentially a loss of reverse gear, all resulting from a failure of the planetary gear assembly
Solution – Install planetary upgrade kit and new torque converter

TSB 02–21–1 – 4R100 Transmission – Torque converter access plug may become dislodged

1989 – 1997 Ford Super Duty – 1989 – 1998 Ford F250 – 1989 – 1998 Ford F53 Motorhome – 1989 – 2003 Ford E-Series – 1989 – 2003 Ford F150 – 1999 – 2003 Ford Super Duty – 2000 – 2003 Ford Excursion – 1998 – 2003 Lincoln Navigator – 2002 – 2003 Lincoln Blackwood
Problem – Due to extreme load and material shrinkage, the torque converter external access dust plug may fall out during severe duty use.
Solution – Install new plug (part number E9TZ-7N171-A) with a 1/4 inch bead of silicone sealant around the plug.

TSB 98-20-9 – Ticking noise on initial startup when the selector is in park or neutral – 4R100 Transmission

1998 Ford Econoline – 1998 Ford Expedition – 1998 Ford F150 – 1998 Ford F250 – 1998 Lincoln Navigator – 1999 Ford F250 HD – 1999 Ford F350 – 1999 Ford Super Duty
Problem – A ticking noise may be hard when the vehicle is first started and the shifter is in the ‘P’ or ‘N’ position. In some cases, the noise may also be heard after the vehicle has warmed up. This can be caused by the overdrive clutch steel separator plate(s) hitting against the case internal spline.
Solution – Install new OD friction plates and accumulator assembly

TSB 10-18-1 – Delayed forward/reverse engagement after cold starts – 6R80 transmission

2007 – 2010 Ford Expedition – 2009 – 2010 Ford F150 – 2009 – 2010 Lincoln Navigator
Problem – Some vehicles equipped with the 5.4L engine and the 6R75 or 6R80 transmission may experience delayed forward and/or reverse engagement after a cold start or in cold climates. The P0741, P0731 and/or P0735 DTC’s may also be present.
Solution – A new front pump adapter seal and separator plate will need to be installed. The main oil pressure regulator valve and its bore may also need to be cleaned.

TSB 11-8-4 – Fluid leak from bell housing – 6R80 transmission

2011 Ford Expedition – 2011 Ford F150 – 2012 Ford Mustang – 2011 Lincoln Navigator
Problem – Some vehicles built between 4/15/2011-6/8/2011 may experience a transmission fluid leak coming from the bell housing area.
Solution – Install updated transmission pump assembly

TSB 14-0217 – Delayed engagement park forward or reverse

2011 – 2014 Ford Expedition – 2011 – 2014 Ford F150 – 2011 – 2014 Ford Mustang – 2011 – 2014 Lincoln Navigator
Problem – Some vehicles may experience a noticeable delay when trying to engage a forward or reverse gear from Park. This can happen with the vehicle is cold (i.e. has not been driven for several hours).
Solution – Install updated 6R80 transmission pump

TSB 18-2079 – Harsh or delayed shifting and/or P0711 DTC – 10R80 Transmission

Problem – Some owners may experience usually harsh or delayed gear changes. There may also be a P0711 diagnostic trouble code saved in the transmission control module
Solution – The powertrain control module will need to be updated with new software (release 108.04 or higher). Once the update is complete, the adaptive transmission shift strategy program may temporarily cause usually firm upshifts and downshifts while it ”relearns” your driving style.

Ford F150 3rd gear shift problems

While the F150 is usually a very reliable beast, 2001 and up models equipped with the 4R70W/4R70E or 4R75E transmission can develop a number of issues over the years. Like Ford F150 3rd gear slipping for example. During the 3-4 shift, the transmission will slip into neutral instead of engaging 4th gear. There may also be a lack of engine braking if the transmission is manually shifted into the 2 position.

What causes the Ford F150 3rd gear slip?

These F150 shifting problems are likely due to a broken overdrive servo retaining snap ring or overdrive servo piston ‘E’ clip. Should this happen, the pieces from that broken snap ring or clip can make their way into the overdrive servo regulator valve, preventing the overdrive band from making a full apply. After the broken parts are replaced, that overdrive servo regulator valve assembly needs to be removed from the valve body so that any damage from the broken pieces can be repaired. Most mechanics will overlook this, resulting in more transmission problems somewhere down the road. Street Smart Transmission on the other hand, is very familiar with these transmissions and always inspects for this damage during every reman F150 transmission build.

How much is it going to cost to fix my 4R70W/4R70E or 4R75E transmission?

Unfortunately, the problem described here will require the removal and disassembly/partial disassembly of your transmission. Given the labor time involved to remove the transmission from the vehicle (this is not a simple task), most repair shops will recommend that you go ahead and rebuild the entire transmission while it’s out. Since they already have to tear it down to replace the 4R70W/4R70E or 4R75E transmission, it sort of makes sense to spend the extra money to do that. After all, you should get a lot more mileage out of your transmission once it’s rebuilt. And since they’ve already got the transmission apart, might as well, right?

Can I drive with a transmission problem?

Okay, if your truck 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. 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 F150 transmission need to be replaced?

The overall lifespan of a Ford F-150 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 OE Ford F-150 transmission last for between 130,000-220,000 miles. A high quality replacement Ford 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 F150 SD transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Ford F150 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 F150 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 F150 transmission replaced?

In order to replace your Ford F-150 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, the ECU will have to be reprogrammed to accept the new gearbox.

How to Solve Ford F150 Transmission Problems

Solution A: Buy a Used Ford F150 Transmission

The quickest way to fix your transmission problems is to simply buy a used 4R100 or used 4R75E 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 F150 Transmission

Another option would be a rebuilt 4R75W or 4R100 transmission or rebuilt 4R70W transmission. A local repair shop will remove your F150 transmission, then install a bunch of new parts. The problem here is, the skills and experience of each mechanic 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 F150 Transmission

Many owners depend on their Ford F-150 to make a living 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 2001 f150 4×4 supercrew 5,4. After hurricane Matthew I drove through water to check on my wife’s family. Two days later my truck once it hits 35 mph. It seems not to shift into overdrive and it revs up and won’t accelerate. I can get to 55 but I have to cut the overdrive off. Could it be solenoids? Overdrive band? Computer?

I bought a 2000 F150 last year. The truck has 4X4, with a 4.6 motor and seemed to be a pretty good truck at first. I started having trouble with my truck when I would pick up speed and it would act like it would shift into neutral. Needless to say this wasn’t safe. Next, when I was backing up I heard what seemed like a rattling noise and then a loud pop and the truck jerked. I stopped. I was then able to put the truck into drive, and the truck drove forward fine, but it would not go in reverse. I have been checking out some of the other complaints on other websites and it seems to me there are a lot of problems with the transmissions.

I have I believe an ’06 ford f150, 7 days after I bought it the tranny went completely out. Took it back and the warrenty stated we had to pay half to rebuild the transmission. $1,000.00 and 9 months later my truck won’t click into gear. It starts up but it just revs in drive. Is it my first gear? It goes in reverse just fine. Our warrenty for the rebuild was only for 6 months!!! PLEASE HELP!!!

I have a customer 2012 F-150 5.0lt coyote engine. We did an engine swap, per customer request with an exact replacement crate engine. Everything has been fine, however, now on the dash, when the vehicle is in drive, it is showing the gear shifts, as if the vehicle is in manual option. There are no codes, and as far as I can track with my computer, nothing wrong with the transmission. Suggestions?

You can turn the gear display off and on. While in Automatic Drive, press the manual shift up to turn it on, and down to turn it off. I like to keep mine on so I can watch shifting patterns. Unfortunately, at 34,000 miles, mine has developed the first to second gear lurching problem reported here and elsewhere. Other than that, great truck.

I have a 2011 Ford F150 Supercrew Lariat w/5.0 V8. It currently has just under 114,000 miles on it. Love the truck. My only problem with this truck has been a concerning transmission. Often, but not always, when beginning to drive away in a parking lot or bumper to bumper traffic, the tranny drops into second with a large bang. Sometimes its mild other times it literally feels like you’ve been rear ended.

This has occurred almost from day one. I’ve brought the truck back three times over the its life. The first time Ford applied a Technical Service Bulletin, no success. The second time, they told me Ford is aware of the problem but does not know how to correct it. The third they did a software update. Nothing has worked, it still does this. Now after 114,000 miles, I’m hearing some play in the rear U-joint.

How do I get Ford to install a new transmission?

I have a 1996 Ford F 150 4 by 4 with a C6 transmission and it’s slipping while I’m driving I step on the gas and it seems like the truck doesn’t want to go nowhere if I let off the gas it seems like it wants to catch into gear this is a junkyard transmission I just took out the other one and put this one in and I’m having the same exact problem I’m wondering if it’s the transmission or something else what could be the problem thank you I need help badly

I pulled my 07 ford f150 stx 4.6 into a friends driveway over winter while in 2wd, when I went to reverse out I started to spin a little but so I made sure to completely stop the engine from revving, and wheels from spinning. I put it in neutral then twisted my dash 4×4 switch into 4high. Once the 4high light showed up on my dash I switched it into reverse anddddddddd NOTHING! A message then appeared on my dash saying “trans fault” or something to that extent. I have all my forward gears and neutral, when I switch into reverse it feels like it kicks in but when I press on the gas all it does is rev up. I refuse to pay thousands of dollars to have a shop fix it so I am hoping for any help at all.

Thank you

I have a 1994 f150 5.0. About a year ago I noticed that while driving for extended periods of time, my transmission would slip for a second ( like going into neutral ). I also feel a slight snag when the truck switches between 1st and 2nd gear. I had the truck checked out and the guy told me the torque converter is going out and I should have the transmission rebuilt. I’ve drove the truck for almost a year now without having it repaired. I only drive about 15 miles a day and don’t take it on any long trips. I’m wondering if anyone knows a rough estaminet to have the transmission rebuilt. This is an automatic transmission with overdrive.

I got a call from my sister to go pick her kids up from school in my 97 ford f150 xlt with 4×4 and my nephew accidentally bumped the 4×4 on low and I hadn’t noticed, a few days later when I got to my sister’s house (where I park my truck for work) I tried to go home but my truck would barely accelerate. It sounded loud like it had lots of power but it would barely move. I can go forward and reverse but with minimal speed. Finally when I realized that the 4×4 low was on, I took it off and it still ran the same. I checked all the fluids and they were good but I also checked under the truck where the transmission was and it was wet like something had been leaking. The drive shaft was still sturdy, I removed the positive connection off the battery for a few minutes and still nothing. Can you please give me an idea of what could be wrong with my truck?? Thanks

I have driven a number of Ford F-150s (I used to sell trucks, among other things) and I have run across the problem you are talking about. Actually, you shouldn’t be hearing anything at this point if it’s new.

I know it’s not the transmission in your F-150, however, it is related to the drivetrain, specifically, the universal joint. Now, I am assuming that your F-150 has four-wheel-drive. Since it does, there are actually two universal joints, one for the rear wheels and the other for the front. I suspect that since your vehicle must have been sitting for a length of time that some of the fluid in the U-joints has evaporated and the level has dipped. In this instance, the gearing in the universal can set up quite a racket. I’d have the dealer check there first.

Also, you may want to check the transmission fluid level as it may be down significantly and that, in turn, may be causing a bit of metal-on-metal grinding which isn’t a good thing, at all.

Finally, the old gag about putting in heavy (Lucas) motor oil to fix everything is really just that an old gag. Yes, it may quiet things down but if you don’t find the root of the problem then you are going to have a gooey transmission with the same issues.

Since your F-150 is new, by the way, the dealer has to fix it.

And, why do they sell vehicles with known issues. There are so many possible reasons that it’s tough to tell why. Suffice to say, it’s all profit motive.

I purchased a Ford F-150 Triton from a dealership. The day after I hear a strange engine noise that I’d describe as “grinding”. I immediately called the dealer and let them know. The manager said that the noise is most likely due to the truck not being drive for a long time and because it was raining. When I called back several days later (the noise was still happening), he told me that particular model often makes that noise. He suggested I put Lucas motor oil and everything will be okay.

This can’t be true, right? Why did they sell me a vehicle with know issues?
