Looking at the guts of that transmission, and thinking about the design and machine work that goes into making one, I can't believe the transmission alone doesn't cost $100K. Amazing. Thanks for showing us what's inside.
Some serious mechanical engineering with these transmission designs. SMDH over how complex and how people engineer this is totally mind blowing. As well, competent techs that can work on this are also well worth their weight in Gold!
Automatic transmissions like this are one of those things that makes me believe we have alien technology on earth.
The "Bob Ross" of transmission repair. Love your calm and cool. Great video 👍👍
Thanks Peter it was a very interesting transmission.
Yeah, but he doesn't have the hair...which is probably for the best.
Muy buena información y bien esplicado gracias
Nah the post Malone of transmissions.
Wow David
That was a roller coaster video.
I am just a back yard shade tree wrench hack since I started working at a local auto wreckers when i was 12 in the 80’s and played with saw milling and mechanics most of my life. Was watching this vid and started feeling overwhelmed with that trans. I run a 4L60e in my chevy van and a th400 in my 66 buick.I usually don’t get overwhelmed but this is my first time seeing one of those trannies. Was really feeling down on my skills watching you, then at the end your explanation of how to take that trans and compartmentalize it clicked in my head and i got it. And it is great when the pros share their knowledge freely
Thanks again for the great insight
Cheers .
Cheers as well thank you for the comments. If you ever feel overwhelmed building one holler and I'll gladly give as much information as I can.
Well spoken Darren. I too was given confidence by watching to the end. Love David’s delivery of information, his patience, his delight in mastering the stubborn snap rings, and apparent successfully enjoying what sustains him. It’s those who share for the joy of witnessing another’s success are Gods children. That Him within each of us is how we all ascend together lifting each other. Journey Well
Brother you are a dying breed just like you mentioned. You had my attention from the get-go. Great tutorial and I gave you the 👍 up.
Thank you for that
Glad this came across my UA-cam feed. I have a twin turbo 2018 Mustang and it’s 10R80 messed up on its 3rd pass down the strip. It freewheeled on the launch then crunched back into gear when it idled down. Sticky tires always finds the weak spot!
Everytime lol
What’s the benefit to extra capacity clutches???
Check the C3 drum because it has a factory defect, the sleeve moves forward
How much are you looking at for just labor? To rebuild the transmission
Very nice explanation, but tell me why any tranny would not have a dip stick? I think this is like buying a truck without a steering wheel . 55000$ dollars and no easy way to check fluid level. Thanks again.
Very much appreciate you giving your knowledge out for free. Particularly at the end about shop s. Nowadays parts replacers no builders. Sad
Dude… I was racing that car just a week before I dropped it off. 😳
That's insane I'm glad we got it apart it was crispy.
@@expressautotransmissiondav4207 I’ll have a video up soon of my race versus a ZL1 Camaro. I needed what little clutch material was left. 😂
Rww
I have an s650 it’s my first but I see inline that the 10r80 can handle a lot of power over the MT82 which I wanted but I opted for the auto because of the power it can handle. What happened to this trans?
@@E85_STI Either it was bad from the factory or the tunes I was testing from Edelbrock ruined it and burned it up. After this rebuild and a PBD tune it’s still going strong. I did recently swap rear gears from the 3.55 to 3.15s. I have not been able to make a full WOT pass yet due to the cold roads, but it daily’s 1,000x better around town already without a new tune for the gear change.
💯👉No chance in hell of me putting that thing back together again and it working😭.... good video.
I'm sure with some guidance you got this lol
This is third utube search I've done for the 10R80, this time I was looking at the Ford Ranger 3.2L diesel and NOW this video comes up... Wow. Yes I'm in the USA. I'm now glad the 3.2L is not available here.
My 2019 F150 has been at Future Ford in Concord CA. for 3-4 weeks with a 4th gear slipping. 1st time the dealer fixed was 1st gear shifting into neutral at apprx 55k miles and now 86k miles my 4th gear slipped and 3rd started to go just before i dropped off. The trans.overheated on me twice. i called dealer to let them know and becuase no dip stick i cannot check fluid easily they checked for me and said fluid was fine.... After watching your video i see now where the clutch packs are located and have much more info to talk to dealership trans tech about. Ford warranty will only let dealer do code check program and check and code check and inspect and replace parts for code. this is BS! I will be calling FORD customer service to figure out why the techs cannot do a proper repair job the 1st time.
thanks for the tear down, Iv'e got one of these transmissions in a ford ranger in Australia, with a 2lt bi-turbo diesel engine. Fingers crossed. hahaha
Geez this is why I don’t want to super charge or heavily modify my S650 because it’s still under warranty and I don’t want to deal with paying or trying to fix it if something should happen. How do these clutches get hot like that? Low fluid or dirty fluid?
Where’s the build video!? Please! We need it! Also need info on what to do about the valve body. Thanks!
Is the Torque converter the problem of the factory tuning thats causing the converter to fail?
Crazy, I’ve been seeing a bunch of these ford 10-speeds breaking.
Did I miss something about the torque converter at beginning
I'm not a mechanic but would suggest being VERY careful when setting down and pulling apart the various components during this disassembly. I would avoid letting anything drop down to your metal table as much as possible to avoid denting important parts. Scared me a couple times to be honest ;-) but awesome video!!!
Great video. Keep up the good work.
THANK YOU!!! Your advice on heat checked steels is spot on. Also, I read ULV fluid is really bad on skin...what is your take?
you make me wanna tear down my trans thats a lot of insperation for me to do that lmfao badass video man
Thank you I appreciate that lol
Hi from dubai. Thanks for great information videos
Thanks
The stator is loose in the converter by design. That is not an issue.
Is the torque converter not supposed to move like that?!?!? Lmk lmk!!!!!
I completely enjoyed this tutorial, thanks, I have a 19 Ranger with this in it, yes this gearbox is problematic, it's new and has teething issues, we JQPublic are the test bed. When it works correctly it is butter smooth and at 80 mph my little 4 banger is only turning an RCH over 2 grand. Can these gearboxes be built bullet proof? Cause I really like the truck. Thanks again.
They can be bullet proofed just watched a video of one the other day

Great stuff, yeah, I did many M1 tank transmissions, and many others, I'll be honest, I think the newer belt transmissions work better overall, I own several and the cars just feel a lot better, I do have a mustang with the 10 speed and to me it feels clunkier, the continuous up and down shifting just becomes a pain, it tries to stay on higher gears to keep rpm down for fuel economy and it bogs down the engine and creates droning quite a bit. On the belt driven is very smooth up or down on the other cars. Just my 1 cent, cuz I owe the other cent to the IRS!
wwhat is the right silicone?? i looked for it but cant find it- and ford dealer had no idea when i asked about it.
Isn’t it supposed to skip 2 and 4 gears under normal acceleration?
Hey Excellent video breakdown of this tranny. And yes you are very calm disassembling. It’s beyond me why they use any O-Rings in this since it’s emerged in fluid
You should talk to your Cornwell man about a good snap ring puller set. I have several.
Great video love the explanations and jokes
I have a ranger raptor fitted with the 10R80 she runs fine, but if you don't drive her for several days, when you select drive it can upto 15 seconds to drive it will only creep, is this common to thease boxes, or is it a problem waiting to happen the vehicle has done 19000 miles
So what caused this transmission to fail? I see slipping clutches as you pointed out. Could it have been just too much horsepower that exceed the factory's OEM design?
What’s the roundabout cost to upgrade the clutches in 2019 mustang 10r80?
THANK YOU VERY MUCH, oNE QUESTION I HAVE A 2018 MUSTANG AND IS HAVING ISSUES WITH HARD ENGAGEMENT NO CODES, HAVE YOU HAD ANY PROBLEMS WITH VALVE BODY? I DROP THE PAN AND THE FLUID IS OK NO CLUTCH OR METAL WEAR.
Hey, I don't even go here but this was entertaining as hell. What could the driver have been doing to cause that? And on every single, last clutch? Or is this maybe not the driver's doing?
It was a mixed failure caused by several different elements.
@@expressautotransmissiondav4207 Could you please tell us more what caused it? I'd like to avoid doing that to my trans.
Geez that thing is huge! No wonder new Mustangs weigh so much.
What? Every video I have seen says yet another bad part....the clutch hub ,the valve body ,the converter, is there any thing that was done right ?
Is it ok if for example I have a transmission like that and I want to fabricate metal oil pan using stainless steel with exact same specs would it still work ?
Master, I have one of the exact same year, only mine is a 4-cylinder turbocharger, when I put it in drive it hits and when moving the gears up it makes them very cool but when going down in fourth gear it hits a bit and I disarm it and all the clutches are like new, just notice that the converter makes a sound when moving it, any idea what it could be? thank you so much
nice video. is it the exact same trans in the f150? any internal differences?
Awesome video and install video as well!
Once you fill the 10r80 with the fluid where did you fill it up to?
Might’ve overfilled since it feels like it loses pressure and the rpm flutters. Could it possibly be low fluid as well? Because I did put 11 quarts in it too
I fill mine with 7 qts first start then check. I like to idle till warm and adjust fluid as I go. I set mine at the 60 mark when at full operating temperature.
How’s that E4OD bench video coming along? That thing gave you guys that chills it was so burnt!
Lol yes it was a crispy critter for sure and it's in the works
Great video! Have you ever used mercon LV instead of ULV?
OK for the big Question. How much did this rebuild cost?
Did u happen the check the bushing in the cdf drum? They slip and cause a ton of problems the 10r80s, 10r60s and the 10r140s do it made a ton of cash warranty on them so far
That's a must change part every time
Very good explanation
Good video very detailed!
Thank you were trying some new stuff lol
Are these bad transmissions or are the issues only related to boosting power of the car?
It's because it's modified with 300 more HP than stock.
The 10r80 is garbage, and this is well known at this point. I had my transmission replaced in my 2020 F150 at 26,000 miles. Under warranty fortunately, but there's no excuse for that kind of failure at that mileage. Boosting the power of the vehicle isn't the issue. Ford didn't design this transmission correctly, end of story. This kind of nonsense is exactly why class action lawsuits exist, and I do believe Ford may be facing one due to this transmission. Valve bodies, CDF drum issues, and so on. These transmissions are absolute garbage.
Very good video brother
awesome video brother
Where exactly are the gears in the transmission? I see a whole bunch of clutches and the planetary gear. I have a F-150 with one of these and it's been one of the best automatic transmissions I have ever experienced. The 8 speed in the rams and chargers are top notch as well.
The "gears" are the different results of planetary gearset manipulation. Planetary gearsets have 3 main parts, the ring gear, the carrier & the sun gear. The input usually comes in via the sun gear, and the output on the ring gear. The clutches are responsible for either holding, or releasing the various parts of the planetary. You really need to see it in motion to understand fully. But it's all about power flow, how it's being sent through the transmission, which planets it is or isn't flowing through, which thus creates a gear ratio.
My friend has F150 5.0 with this trans and he used it like a F250. Now it needs a tranny.
I've got a 2020gt 10spd auto so far so good I'm going to replace trans fluid soon as I've done the diff so figured may as well so trans car's got 50k on it. I was curious what causes those black scuffs on the disc's that you said have to be replaced, I'm not very familiar with transmissions I just know you put it in gear and go no idea what causes these things you've pointed out. Lol
Did you change the fluid yet,and what's your mileage? I have 76k stock, but my guy won't touch it until 100k as my cars are 80% highway with small amount spirit driving but no racing.
Good information, thanks
Hey, light highway on half of my 32K miles. Do you suggest getting the fluid changed? Not flushed, just drained and filter changed at then?
Absolutely
Is this one very similar to GM's 10L90 and 10L1000 "Allison"?
It is in a lot of ways we may do a dive by side comparison of the two
Do you know the torque spec for the three 15mm mounting bolts in the rear of this transmission? thanks so much for any help
Would a transmission cooler off of a raptor or police vehicle helped keep,this trans alive?
I have a 22 F-150 with the 5.0 and 3:73 full towing package. NO upgrade on the cooler.
I honestly think it would make a huge difference..
No trans cooler with the max tow package?
How many miles did this Transmission have on it? I'm getting these same shift problems in my 2021 Ranger only 46,000 miles and looking for info about service bulletins, recalls and warranty. More so what totally should be done by Ford. Have heard talks that there is a classaction lawsuit going on with these transmission?
@@paulk1187 6,000 miles on it.
@express thinking about getting a 2.7 f150, are these 10r80s reliable ? man these trucks are expensive
So far they have been. I have seen some issues with the f clutch housing as well as a few other things but overall they have been great.
thanks for the insight. great content.
I know this is a 10r80, but how many actual gears does it have? Doesn’t the torque converter have anything to do with the number of gears?
From what I understand, it's a 5-speed with a splitter for 10 ratios.
The torque converter has nothing to do with the number of gears.
Thank you Sir!
I’ve seen other 10R80 tear down. In your video I don’t see an auxiliary pump behind the filter. Is this a normal configuration?
No start stop function on certian 10r family.
@@expressautotransmissiondav4207 thank you for the quick reply. Great information you passed along. Even a novice like me understood it. My Ford Explorer ST is currently at the dealership with slipping, jerky gears. I don’t abuse the SUV therefore I’m hoping it’s a solenoid issue and not something more internal.
Can we just make manual transmissions mandatory?
Indianapolis cold cold not doing and wrench snap untill April may
Lol
Who makes that tear down table? That’s nice.
I bought this one from cornwell tools
@@expressautotransmissiondav4207
Thanks for the reply! I’ll be hitting up cornwell. Great videos btw. Keep it up.
Thanks
Would you say if needing an auto for a mustang gt just stick to the 15-17 6r80? Cause it seems like these 10r80s can't handle anything past bolt ons. Even that seems debatable.
I prefer the 6 for bigger power I personally don't think there's enough aftermarket support for the 10 yet
@@expressautotransmissiondav4207 Yeah, I been looking for a Coyote and honestly all of these 10r80 issues have me just wanting to pass on the 18+ and just be happy with the 15-17. Would you say just get the 15-17 at this point? Also, are they that much slower?
Not with some add ons lol
@@OLLI_UPthey’re slower for sure. You can go e85 stock fuel system on gen 3. Its worth it, the 1080r is decent for bolt ons. If you have the money to go past that idk what the issue is if the trans fails. You got money
What about hot spots on clutch backing plates, do you replace those too? I've currently got a 6l80 torn down that has a hot spot on the 3-5-R clutch backing plate.
Yes hot spot replace
Is there a reassemble video for this trans?
We don't currently have one but one is in the works
Being that I have a 2019 GT, it concerns me to see all these transmission teardowns in cars that are only two or three years old. WTF?
Sadly it's becoming more and more common .
it's the result of throwing a bunch of power adders on the motors to already high octane cars and doing zero to help support the rest of the car. Or its people messing with the tuning and transmission who aught not to be, but neverthless, can't just increase power by 30% give or take and not do any work to anything else. No one builds anymore, they just slap something on the motor crank it up and break things.
If you watched the video where this trans was removed from the car, he mentions it has an edelbrock supercharger on it so stress on the trans is far from factory design.
Don't drive it hard and get rid of it asap.
People are passing away out this business.
Lots of hotspots… burnouts?!
That looks like a job that would take me a whole lot of cussing 🗣
I think this person did a Mexican roll all the way to Mexico
Taking this transmission apart is likely eating that grissly piece of steak, the more you chew, The bite just keeps getting bigger and bigger.
I’m a ford service tech by trade, I’ve only been doing transmission work for about a year now and i must say this is the worst condition 10r80 I’ve seen. I just recently overhauled a 10r that had b,f,e clutches worn where the steels had hot spots. I’ve had a couple of cdf drum bushing spin and move too in the drum.
Those are always fun. I've had them grenaded and had several in with the e clutch wiped they are definitely going to be fun units in the future
I don't know what would convence me to own Ford's
Very possible ...but I been with GM like bananas many years ect
I don't have a auto income
I've earned not one cent in Costomer repairs..Retired Machinist interest in technology
This transmission was co-developed between gm and ford so there’s no real win win here with gm vs ford
Lol true story
how the hell do you know how to put this thing back together? lol. i own a 10r80 And i hope I never have to go through this. what does a service like this cost?
I thought these 10 speed mustangs were god and were bulletproof according to everyone who had them. The trans is good for 1200 hp lol.. people are insane or don’t actually hit the gas on their car if they think this will last.
Good to see the 6R80 lead frame gone :lol:
Lol
سلام ارادت.❤️❤️
The real problem here seems to be the driver burning out and over stressing the transmission. I see these sorts on the road and im always like enjoy your 4k dollar repair bill here in a few months.
I agree it is a dying industry. its called work , technicians are a dying breed, were screwed.
Can't they put a aluminum pan first screw up. With that much destroyed my as well get a rebuilt unit from Ford. Or a new one. Once the converter lets go it's over for the rest. Trans lines need to be cleaned new cooler just a mess. They don't need more than a a good 4 speed trannie. A converter on my drag car went out silver oil. Took me 2 weeks on and off to get all that crap silver oil off everything. Should have just junk it and start over would have been quicker. With many new tranny parts today with labor cheaper to buy rebuilt unit from the factory. I new when they came out with that 10 speed it was going to be a mess.
If I Just showed up at your shop and started to r&r transmissions would you kick me out lol?
Nope if you show up everyday I pay pretty good
Where you located.?
Baxter springs Kansas
I’m hoping this car was used to just spin at red lights because that’s scary
Was used for drag racing primarily
Its just planatery gear sets not even close to alien tech😂😂😂 pretty sure like over 100 year old technology
David, didn't your momma ever tell you to close the drawer after you get your utensils? See if you had, you would have never gotten fluid in the drawer. Listen to your Mother. lol
Bhahahahah true true
@@expressautotransmissiondav4207 🤣🤣🤣🤣🤣🤣🤣
As much as you pay for these new cars, it pisses me off to see them using cheaper materials. Plastic trans pan?? Damn...
It's insane what's being made from plastic now
7300 miles and defective. American engineering
Bro you gotta get consent first.
Lol I was gentle
Not if you’re judging by how much she squirted…
Lol that was good nicely done.
Life is full of opportunities.
