Rolling down the interstate at 80 about 600 miles from home and trans went thump! Stuck on the sids of the road. Trans seems to shift but engine revs freely. Truck shifts into gear and into reverse. From a stop I was able to get it to move up 100 yards to park. Had to have truck record to red line to move. Converter broke?

I have not heard that one before. Are you able to contact Ford customer service? Hope that all goes well and you were on your way again soon.

Currently waiting on tow truck. 68k miles on a deleted truck. Past warranty but even if I wasn’t, they don’t like them deleted Hahahah

Diesel powertrain warranty is 5yr/100k miles. For the dealership and Ford to deny your warranty, they have to prove that your truck being tuned was the cause of your transmission issue.

Even better! I was thinking it was 5/60k. Maybe I can talk this dealership into giving me a truck. Lol

I do not believe that is correct. My app says 5yr/60,000

navyR113 is correct. The dealership should be aware of the power stroke warranty and if not ask them to pull an oasis showing your warranty coverage. That has been discussed on here several times. Best of luck

From what I found the Diesel engine is 100K and powertrain is 60K. I hope you are correct. Do you have anything to verify?

 

[Dunrollin]

Duh, you are correct. . See the attachment.

Hahaha darn!! I am really curious what the issue is. It was a thump or like a hard shift at 80 on interstate. Coasted to a stop and it just revs to limiter. Will move like 5 mph and shift into second. Hopefully just the converter worst case. Best case something stupid electronically

Above chart from Owners Manuals is correct:

• 3-year/36K mi Bumper-to-Bumper warranty
• 5-year/60K mi Powertrain warranty
• 5-year/100K mi PowerStroke Engine warranty
• 8-year/100K mi Emissions System warranty
  • On a different page in Owners manual
  • Not specifically listed in OASIS report (for some reason)

and verified by my OASIS report: (pic marked up from a different post so ignore red box)

Looks like you just missed it based on mileage...

Please let us know what they find wrong and what the out-of-pocket damage is...

Please note that both screen captures above in this thread are for my 2018 Ford F150 Platinum:

• Owners manual screen cap is from Post #10 of this Powerstroke Warranty thread
• OASIS report screen cap is partial from Post #19 of same Powerstroke Warranty thread

Later model years may vary/differ, so please confirm your warranties in:

• F150 Owners manual for your model year
• FordPass app
• VIN-specific OASIS report

before trying to execute any warranty claim(s).

@Saathoff05 - you have a 2018 F150 Platinum also, so above holds true for you, but I felt I needed to add a general disclaimer for all owners/forum members...

Dealership called Saturday afternoon. They told me there were no codes, which I already knew and told them 👍🏼

They said the transmission was over 2 quarts low on fluid. Topped it off and that didn’t fix it 🤦🏼‍♂️ I do get a full service oil change every 5,000 miles which is supposed to include fluid check and top offs. I had just had that done, so they have not been checking that.

Without even pulling the pan off they told me it needs a transmission assembly and quoted me $7,100 installed 👀

 

[jmperlik]

Ooooch! That's a shot to the nuts!

10R80 is an expensive transmission new: $5400 via parts.ford.com:

Part #7000 - Automatic Transmission Assembly​

I'm assuming you're also going to check with reputable transmission shops on the cost of a rebuild, which I would hope would be half the cost of replacing with new.

With the 10R80 being a "sealed" transmission, there is no dipstick topside and only a stubby dipstick on the transmission you need to unscrew from underneath. Even the Ford F150 maintenance schedule indicates transmission fluid level is only checked if topside dipstick available:

• Inspect automatic transmission fluid level (if equipped with underhood dipstick)

so I'm sure Ford will play this card to absolve them of the responsibility of checking tranny fluid level during your oil changes.

With your being > 2 quarts low on transmission fluid, I would have hope that a P0868 DTC (Diagnostic Trouble Code) for "Transmission Fluid Pressure Low" would have been thrown before complete transmission failure, but alas you indicated zero codes were thrown.

I've seen multiple comments on various forums about Ford intentionally shipping vehicles from the factory with the transmissions short at least a quart of transmissions fluid to save Ford $$$, though I can't understand how they could do this if they truly intend for the 10R80 to be a sealed transmission that isn't intended to be touched until its first fluid change at 150K miles.

I've been waiting for Richard at Precision Transmission to tear down/rebuild a 10R80, but being a fairly new transmission and his specializing on GM transmissions, I have yet to see a video from them on the 10R80. I've been meaning to ask Richard or Trent for their opinion on sealed transmissions, as 150K miles seems way too long an interval to me, sealed or not...

Sorry to hear the news and I'm not even sure what to say at this point, other than your experience gives me another reason to go with the PPE Deep Transmission Pan at 60K:

DIY Transmission Service Video | Diesel F150 Forum​

and maybe ask my dealer to proactively check the transmission fluid level, even though Ford maintenance schedule indicates they don't have to check. Note-to-self to check with my Service Manager on his opinion on sealed transmissions and after-market deep transmission pans.

Not sure if any of the class action lawsuits on the 10R80 offer any relief, but you can google on that term or reference this post on our forums:

Transmission class action | Diesel F150 Forum​

Good luck getting this sorted out.

 

[Laytunes]

@Saathoff05 Dude... that Suuuuuuuuuxxx, especially if the reason it failed was that there was never enough fluid in there to begin with. I've personally never checked mine as i would trust that the fluid level is correct from factory, but dang maybe I should get my ass under there and see. Anyone else checked theirs yet?

Found some old (2014) but interesting articles that attempted to reverse-engineer how the 10R80 transmission works from the patent filings:

​

An Inside Look At Ford's New 10 Speed Transmission - The Truth About Cars​

Saturation Dive: Ford 10 Speed Transmission Power Flow - The Truth About Cars​

I am by no means an automatic transmission expert, but I am an engineer by degree, so I enjoy understanding how things work, even at a 10,000 ft level in the case of this topic.

Interesting tidbits/facts/quotes from the second article:

• If a transmission has 5 clutches and for the realization of a gear ratio:
  • 3 out of the 5 clutches have to be engaged
  • = there are a total of 10 possible combinations
• ZF 8HP (FCA) and GM 8L transmission families have 5 clutches of which 3 are engaged for any gear state:
  • Only 9 out of these 10 states are present & accounted for:
    • 8 forward gear ratios
    • 1 reverse gear ratio
  • The 10th combination leads to a situation where the transmission would want to turn in forward and reverse direction at the same time
    • i.e. transmission would lock up the output shaft and potentially self destruct
• If a transmission has 6 clutches and for the realization of a gear ratio:
  • 4 out of the 6 clutches have to be engaged
  • = there are a total of 15 possible combinations
• Ford 10R transmission design has 6 clutches and 4 are engaged for any given gear ratio
  • 11 of the 15 possible combinations are used to yield:
    • 10 forward gear ratios
    • 1 reverse gear ratio
  • The 4 other combinations do not yield a functional transmission gear state or put the transmission in Neutral
• The genius of this design is the use of an intermediate shaft which is connected to 3 of the 6 shift elements
  • This intermediate shaft allows for 10 well spaced ratios between highest & lowest gears
  • It also simplifies the hydraulic system of the transmission because hydraulic power for half the shift elements goes through one rotating shaft
  • This kind of design is far too complex to be totally invented by a human because there are simply too many permutations & combinations to consider when evaluating a power flow
    • Therefore candidate designs are typically brute forced by computers and subsequently short listed and refined by humans
    • The use of such an intermediate shaft that is not directly connected to any of the planetary gear elements is truly unique

Spelling things out like this made things easier for me to understand, as my expertise is in the Computer Engineering field where my Senior project was designing & building simple state machine. While my Senior project was implemented using digital circuits, an automatic transmission looks like a hydraulic state machine to me!

@Saathoff05 - not sure if any of this would help understanding what went wrong, but I found these articles interesting and informative. Having watched dozens of automatic transmission teardowns on the Precision Transmission YouTube channel, I think the only way to find out what truly went wrong is for a reputable transmission shop to perform an autopsy...

Please let us know what (if anything) you find out, as I think you have everyone's attention on these forums.

Mine went down on thanksgiving day. Same symptoms. Deleted and taken care of. I was informed by someone that it was the pump that went out, sending debris through the entire system.
Truck was at the dealer almost 90 days.

"I've personally never checked mine as i would trust that the fluid level is correct from factory, but dang maybe I should get my ass under there and see. Anyone else checked theirs yet?"

Me neither, too lazy. But looks like I am going to soon though! I suppose I should stop by my Ford dealer first and grab a quart of ATF just in case I need it...save me a trip.

I experienced a total transmission failure at 5200 miles. Ford dealer pulled codes and Corporate r&r’d with a brand new unit in the crate from the factory. Replaced under warranty. Dealer invoice showed $8500 parts and labor.

 

[jmperlik]

Looks like time for a tracking table!

@GearsGrindn - Was your transmission replaced under Ford's Low-Time-In-Service Assembly Replacement Policy? I'm assuming Yes based on "new-in-crate" comment and associated cost.
