My 10r140 had this same problem with the bushing in the CDF drum, 2022 F350. Was making a grinding noise and vibration on the 4-3 downshift. Did so from day one, 13 miles on the odometer. Sat at the dealership for 6 months because the sealing rings were on backorder. When I got it back, only made it 5 miles before the new bushing shifted again... Randy's Godzilla 10r is the only solution I have researched so far, they claim to "stake" the bushings to keep them from shifting.
Just got the valve body and cdf drum replaced at the dealer on my 22 f150. So far, so good. I dont know why they won't issue a recall.... well, i do, but still. Sucks its just a tsb.
I used Motul VI transmission fluid and filter on my 10r80 and solved everything. Its not gonna repair any damage, just the cold morning jerks, from drive to reverse jerk and so on. 3-5 shift smoothed out, 2nd and 4th also shift better. Shifts are crisp and quick, when slowing down and punching the gas its always in the right gear, but before it seemed like it was searching.
My transmission does the same thing. Almost goes away completely when warm. Except 8th gear shifts a little hard. Do you think this is most likely my problem? Also where can I order parts? And where can I find parts diagram with part numbers for internals. Thanks in advance.

Thanks for a great video. I have a better understanding of what is being done to my 2019 F150. CDF drum failure and a bunch of metal shavings I was told. After three weeks I hope I get my truck back this week. At 69,000 miles it is just past the powertrain warranty. This $4800 repair just paid for the extended warranty a couple of times over.

Thank you for your vedios. I wish your shop is near Seattle! My 2021 F150 transmission when up to working temperature, it will start having some whining noise during shifting, especially from 1 to 5 gears, above 5, the no noise or maybe unnoticeable. But within each gear, everything is good no noise. And each gear shift is very smooth if I don't push gas pedal. Downshift though, sometimes it has a bump from 4 to 3,but if I control the brake pedal, I can avoid it. do you know what to do to fix the noise? It is not loud, bbut annoying to me. Thanks again for your great vedios.
Thanks for watching, I'm glad the videos are helpful to you! Some whine is normal on those due to the offset pump drive gears. And firm shifts are pretty much normal too. Ford can run an accelerated break-in or clean the valve body which can help with random firm shifts. But they all get firm sometimes
Since this transmission is codesign by Ford and Chevrolet, is this CDF bushing issue a Ford problem only or does it also appear to be an issue with Chevrolet?
Any chance you could show the difference between the new and old CDF drum so we can see what changes Ford made to prevent this from occurring again? Great video!
Is new CDF drum modified to prevent it happening again?…I have 2019 in shop getting new cdf drum , do you recommend any other upgrades like valve body ect?Thanks for great video!
@stevewhite7649 yes, it's modified to prevent future issues. While you're in there I'd get the updated design planetary container cylinder, and of course new sun shaft Teflon rings (where it slides into the cdf)

Excellent videos! My 2020 F150 is waiting on CDF replacement. Intermittent hard shift 4-5 and 7-8. I sure hope my dealership has someone as knowledgeable as you because this is deeper than I was hoping they’d have to go!
@@Spicy.22I have problem 10l80 no reverse.. I open and change all seals and clutch together with converter.. Still same problem.. When you put in reverse nothing at all..
Im having issue with my 2021 f150 it’s got just over 65,000 miles just started 3 days ago. Truck suddenly shifts a bit hard into drive after driving it for a while and it had a slight harsh/bump feeling when shifting from 4th to 5th and only in light accelerations,(almost every time when trans hot) mid to high acceleration shifts perfectly into every gear. Don’t have any issues when cold. I tried clearing the trans adaptive tables and no luck (does down shift smoother after) could this CDF from be the issue? If not should I be worried about it? No one else feels the shifting concerns but me Forgot to mention I did do a trans service (fluid change and filter) at 60k miles (1st one) should I be doing services sooner maybe 30k? I do have a extended aftermarket warranty but I’ve always done my own services and repairs
I hate this trans. My 2017 never shifted right, bangs into drive, 1-3 and 3-5 shifts cold feel like you get rear ended. Starting to shudder and slip now, everything getting progressively worse. All the dealer ever did was a adaptive shift re-learn (which I have been doing monthly to try and make it liveable) or tell me "you don't know how to drive it right". Well it's out of warranty and now my $10k problem if I want it to work. Fords not getting a dime, Suncoast trans and torque converter. Who needs to do warranty work when you have months of retail work I guess.
I do have a question. My 2019 f150 had to have a transmission rebuilt under warranty. But before they rebuilt it they tried to reprogram it and I was driving 70 mph and it shifted from 10th gear to 1st. And just messed a lot of the transmission up. But anyways after they rebuilt it. Sometimes it still shifts hard and jerky
Shifting from 10 to 1 may have been a cdf bushing fault. Your remaining jerky shifts are likely characteristic, but if it doesn't feel right to you, you can have them clean the valve body and install new gaskets under warranty (if you still are)
Dang, I wish I cudda seen ya Pull that outta the Truck...🤔. I get that it's a Warranty Repair Big Ben, but why aren't the Clutches, and some other known Defective Parts just replaced while the Trans is Out of the TRUCK? (Or a New Updated CompleteTransmission) That's a Ton of work to just replace a Few things. It just seems as tho this Issue is just gonna keep coming back??? Isn't it. And sooner or Later, the Customer is going to get Stuck with a Hugh Repair Bill down the road. I here tell this Tranny can be 4/8K when Replaced. It looks like a Lot of Defective Part's are just being replaced, and all the rest is just Re Installed?
Hey..the clutches are in good shape, and the only common internal issue is the cdf drum on trucks older than 2022. The drum I'm putting in is redesigned and they shouldn't have an issue again out of this transmission for a long time. My hands are tied with warranty work. Especially this one. This is a technical service bulletin. I have to follow ford's instructions to a T, or they will refuse to pay. Then I will get charged for it. If it were up to me, yeah a fresh new transmission would be nice for them. Or a complete rebuild. But Ford doesn't want to pay for all that. Just the bare minimum. Thanks again for watching. This is a remake of my previous teardown video. That video was sideways lol.
@@BigBensCarsAndCycles, I have a 2018 F150 with this transmission and it made it to 87,000 miles and now it has failed. It started out having trouble shifting from 1st gear to the next gear and after a few weeks it got really bad. Now it jumps from 1st to 4th and then to 8th and then back to 4th and then it stalls and has no power. I need your advice about what to do. I don’t trust a fix or rebuild because I am afraid I will just have more problems down the road. I am not sure if I have a new transmission put in if it will be with upgraded parts or an old, new stock transmission. So, that concerns me because if it is just a new transmission and it is just like the one I have now, it will eventually do the same thing. My big question is, if I trade it in and get a new F150, which year has the new upgraded parts that will prevent this from happening again? The 2022, the 2023, or the 2024? What would you do? The dealerships are backed up 2 to 4 months on repairs-rebuilds and I really don’t like that option anyway. Also, there are no independent shops near me that rebuild this transmission. If I get a new transmission, that will still take a month or so to get put in and it may be new, old stock, so I am leaning towards just trading it in on a brand new truck, but I need to know which year has the redesign to stop that bushing from moving in that drum and destroying the transmission. Thank You, for your time and advice!!!
@stonecoldflipper9503 I believe late 2022s have the updated drum. So a 23 would be safe. If you decide to let a dealer fix it, this is a common problem and they're knowledgeable about fixing it. And there's not really any other common issues with these other than firm shifts which aren't a big deal - they'll all do it
Very cool to watch this, my question is at this point taking all this apart why not just rebuild the entire thing and not just fix drum? Seems to be a waist of time and energy not to. Or just replace the transmission itself and be done in half the times even for warranty
@@BigBensCarsAndCycles dang that's wild. I changed the fluid in my 10L80 GM 10 speed for my 21 Silverado around the 50k mark and it looked pretty good still. The fluid in that trans looks like coffee. We just picked up a 2019 expedition max and I know the trans is very similar (co-developed) but has their differences. Ford did a better job with the fluid pump vs GM, but apparently did a worse job with that drum 😆.
What seems to be the cause of the CDF drum failure? I have read that it is due to heat and pressure, would you recommend changing transmission fluid at earlier intervals? Some preventive maintenance.
The cdf bushing moves and blocks fluid pressure ports, leading to slip. It's mainly on larger vehicles like an f150 or Expedition. Fluid changes won't help, only replacing the drum with the updated design, which is a permanent fix. But, if I owned one I'd service it every 30k and install an aftermarket metal pan with a drain plug
@@BigBensCarsAndCycles My expedition also has the CDF issue. Dealership says replace the transmission. How can I make sure I get the updated design to avoid repeating? Thank you!
Thanks for the video, very helpful. I have 2 questions for you if you dont mind. 1. Do you typically see other damage in the transmission when the CDF bushing goes, or are they usually like this one and only need the drum and seals replaced? 2. Do you know the part number for the tool used to compress and remove the friction/steels in the CDF drum?
Normally it just needs a drum and #3 sun shaft teflon rings. Rotunda 307-589 is to remove the smaller pistons. 307-741 is for the larger piston. 307-749 is to install the teflon rings
Wow! Looked up those parts - and they ain't cheap! Looks hard to find too. I have a 2017 with 75K miles on it. I'm assuming if\when it breaks this one will be on me. With my luck the cam phasers will break at the same time too.
Good day, any chance you'd have a part number handy for what you call the #3 sun shaft? I'm overseeing the rebuild of a 10R80 and have identified the updated C-D-F drum, but need to source the shaft it rides on as well.
I have a 2018 ford truck f_150 _ with 5.0 V8 and 10 speed auto transmission having problems with both engine and transmission _. Is actually acting like jurking slop clank clunk engaging and disengaging shutters driving away from stop sign/ light when shifting 1st gear upward midway around 3to 8 speed struggling to 10th gear vibration in floorbed driver side and bumb as slowing down with down shifting shoving me into drivers seats as if like someone else coming up behind me shoved me while driving in my truck f_150_
My 2018 Ford Expedition Max 4x4 is having the hard shifting, delayed shifting, shifting from 8th gear to 2nd gear, etc.....do you have an estimated cost on what it is to make this repair?
If your miles are somewhat low, I'd call Ford about it to see if they'll participate in the cost. That sounds like the cdf failure. For cost I'd say 3500 to 5000. I'd have to check to be more precise
@@BigBensCarsAndCycles The wait time just for a diagnosis is over 3 weeks..and ppl say the repair time is actually taking up to 3 months. I decided to just get a new tranny put in for about that same cost as FORD, and other mechanics were saying it would cost to replace the CDF drum, and other parts. Thanks for the videos!
Is there a difference between the 10R80 RWD and 4WD? Was this F-150 a 4WD? Approximately; how much time does this repair take to do? My truck is a 2019 F-150 4WD STX with a 10R80.
Took my truck to the dealer for a flare from 3 to 4 when the transmission is cool. They're doing the valve body first because ford won't pay to do the CDF drum from the start. Why would ford want to do that first if the issue is obvious?
@DetroitMicroSound none of them are granny gears like that. There's just lots of gears to choose from for ideal rpm for different driving situations. The pcm will actually skip several of the gears during normal light driving. Around town it'll go 1-3, then either 3-4 or 3-5 depending on throttle and load
The garbage can had major wear the grooves are supposed to be completely smooth and if not replaced can wear all the way through down the road and I’ve seen it. It’s easy to rewind and pause and see the grooves in them. Can definitely needs to replaced especially for aggressive drives.
@@BigBensCarsAndCycles no so much delay as after each they surging. Maybe engine control issue. I have a 23 NA v6. Company vehicle. Like my 15 5.0 6r80 better. Both f150
My 2020 F-150 had a transmission failure at 74k miles. Luckily I have the extended warranty and it is currently being overhauled by the dealership. Is there a difference in the type of overhaul a Ford dealership does on the 10R80 based on a Warranty repair vs a non warranty repair?
Hi, in my personal experience, with a customer paid repair I may recommend replacing the valve body in addition to the internal repair. That will ensure smooth shifts and won't be a gamble
My transmission does the same thing. Almost goes away completely when warm. Except 8th gear shifts a little hard. Do you think this is most likely my problem? Also where can I order parts? And where can I find parts diagram with part numbers for internals. Thanks in advance.
Hi, harsh 7 to 8 usually is fixed with a new valve body. Strong delay into 2, 4 or 6 when cold is usually a cdf issue. Ford has a tsb for the cdf drum you can print out. Base part number is 7h451 I believe
@@BigBensCarsAndCycles great so you’re telling me i may have both issues lol. I sourced out a new cdf drum. Looks like I can get a new drum assembly for 189$ Do you know how much a new valve body is? And yes you’re correct it’s always gear 7 to 8 that’s harsh.
Hey Ben. I got a question for ya. ya might not know the answer or maybe ya do. QUESTION IS. My 2022 F-150 (Built in March of 2022), just had a Complete Transmission Replacement 10R80 in SEPT, 2023. The New Tranny came from Memphis Tennessee. Would you have a Clue if the NEW Transmission would have Been Updated with the New Bushing and Stuff? I know I'am asking a Lot of ya, But I wouldn't have a Clue at all. Thanks Big Ben.
@@BigBensCarsAndCycles mine is a 2021 I bought it used from a dealerships two weeks ago. Would they have replaced this before re-selling the truck to me? It was blue certified
@@BigBensCarsAndCycles, does the new CDF drum just have better parts or does it also have the lip on it to hold that bushing in place and prevent it from moving and causing the same damage all over again. I have read on other videos where people said when this first started happening that when the transmission was rebuilt all they did was push the existing bushing back into the proper position and put in a new set of seals. That would get you going again, but down the road it would fail again. Then I read that some independent specialty shops started fixing the problem by adding a lip to hold the bushing in place permanently. I just want to make sure Ford is doing the same thing now because my 2018 F150 transmission has failed and I can’t wait several months to have it rebuilt or replaced with a new one, so I have decided to trade mine in on a new 2023 model and hope and pray the 2023 has better parts and that lip. I love my Ford truck and really like everything about it, but that doesn’t mean anything if the transmission or engine has a catastrophic failure before 100,000 miles. If a water pump or an alternator goes out before 100,000 miles, I can live with that, but not an engine or transmission. I have never bought an extended warranty, but I think I will this time because of all the problems people are having. The only problem with that is my truck was out of warranty when my transmission broke, but even if it was under a warranty all the dealers were saying that they were behind 2 to 4 months on rebuilding these transmissions and most of the time the customer had to get a rental and continue to pay their monthly truck payment as well. I am lucky I had a backup vehicle and that bought me some time and allowed me some time to decide what to do. Thank You so much for your help!!!
@@stonecoldflipper9503 2023 and newer 10 speeds have the updated lip drum from the factory. And when they replace it on older ones they install the good one
@@BigBensCarsAndCycles Please allow me to ask two more questions. 1) If you have a record of "hard shifting" as in your dealer is aware but says it's "normal" or has tried to reset shift points etc. and then it craps out out of warranty, has ford been covering those cases? 2) What does this cost for us suckers who have had very hard downshifts, and then it finally craps out and your stuck footing the bill on your own? Obviously this will vary but are we talking 3k, 5k, 10k!?! I'm worried about my 21' that has occasional VERY hard down shift into 5th and or 3rd but only does it every once in a while.
Thank you so much for this video. So my raptor was diagnosed with this problem and I scheduled to change the drum in 2 weeks. It is ok to drive on my old transmission for two weeks (was planning to go to different state) ? Thanks.
You sir, know your stuff, its very nice to see someone talk so eloquently through possibly the most intimidating transmission. Thank you for this, im going to possibly be replacing my output speed sensor. I thought i was having problems on my mustang due to low fluid, got fluid changed and filled, and still got a p0721. If im in 10th sometimes and floor it, it jumps to 7 and wont shift up or down, but no wrench... Fun fun Either way, off my soap box, thank you for the in depth video
@@walkerjohnny72 It will eliminate symptoms caused by this issue. There are chances of other issues coming up with it but it's luck of the draw. the CDF drum is a common issue though.
I think most of these are caused by the EXTREMELY bad Mercon fluid Ford uses. Switching to a high quality ATF like Amsoil seems to keep these transmissions purring along 🤔
Is there a thermostat in this transmission?
Where is it located
2019 f150
Slow heating up
Slow cooling down
Running hot at idle
Issues showed at 55k

If I get a new transmission, that will still take a month or so to get put in and it may be new, old stock, so I am leaning towards just trading it in on a brand new truck, but I need to know which year has the redesign to stop that bushing from moving in that drum and destroying the transmission. Thank You, for your time and advice!!!
@stonecoldflipper9503 I believe late 2022s have the updated drum. So a 23 would be safe. If you decide to let a dealer fix it, this is a common problem and they're knowledgeable about fixing it. And there's not really any other common issues with these other than firm shifts which aren't a big deal - they'll all do it
Dude is like the Bob Ross of transmission repair. So soothing to watch this 😆.
Very cool to watch this, my question is at this point taking all this apart why not just rebuild the entire thing and not just fix drum? Seems to be a waist of time and energy not to. Or just replace the transmission itself and be done in half the times even for warranty
That is some black fluid. How many miles were on this trans?
@@justinschnepf I don't remember. Most likely under 60k. Most of those were done under warranty
@@BigBensCarsAndCycles dang that's wild. I changed the fluid in my 10L80 GM 10 speed for my 21 Silverado around the 50k mark and it looked pretty good still. The fluid in that trans looks like coffee. We just picked up a 2019 expedition max and I know the trans is very similar (co-developed) but has their differences. Ford did a better job with the fluid pump vs GM, but apparently did a worse job with that drum 😆.
What seems to be the cause of the CDF drum failure? I have read that it is due to heat and pressure, would you recommend changing transmission fluid at earlier intervals? Some preventive maintenance.
The cdf bushing moves and blocks fluid pressure ports, leading to slip. It's mainly on larger vehicles like an f150 or Expedition. Fluid changes won't help, only replacing the drum with the updated design, which is a permanent fix. But, if I owned one I'd service it every 30k and install an aftermarket metal pan with a drain plug
@@BigBensCarsAndCycles My expedition also has the CDF issue. Dealership says replace the transmission. How can I make sure I get the updated design to avoid repeating? Thank you!
Thanks for the video, very helpful. I have 2 questions for you if you dont mind.
1. Do you typically see other damage in the transmission when the CDF bushing goes, or are they usually like this one and only need the drum and seals replaced?
2. Do you know the part number for the tool used to compress and remove the friction/steels in the CDF drum?
Normally it just needs a drum and #3 sun shaft teflon rings. Rotunda 307-589 is to remove the smaller pistons. 307-741 is for the larger piston. 307-749 is to install the teflon rings
Wow! Looked up those parts - and they ain't cheap! Looks hard to find too. I have a 2017 with 75K miles on it. I'm assuming if\when it breaks this one will be on me. With my luck the cam phasers will break at the same time too.
Good day, any chance you'd have a part number handy for what you call the #3 sun shaft?
I'm overseeing the rebuild of a 10R80 and have identified the updated C-D-F drum, but need to source the shaft it rides on as well.
I have a 2018 ford truck f_150 _ with 5.0 V8 and 10 speed auto transmission having problems with both engine and transmission _. Is actually acting like jurking slop clank clunk engaging and disengaging shutters driving away from stop sign/ light when shifting 1st gear upward midway around 3to 8 speed struggling to 10th gear vibration in floorbed driver side and bumb as slowing down with down shifting shoving me into drivers seats as if like someone else coming up behind me shoved me while driving in my truck f_150_
My 2018 Ford Expedition Max 4x4 is having the hard shifting, delayed shifting, shifting from 8th gear to 2nd gear, etc.....do you have an estimated cost on what it is to make this repair?
If your miles are somewhat low, I'd call Ford about it to see if they'll participate in the cost. That sounds like the cdf failure. For cost I'd say 3500 to 5000. I'd have to check to be more precise
@@BigBensCarsAndCycles unfortunately Im over my warranty miles at 68K. It does sound like the CDF issue as stated in the TSB 23-2250
@scotprice8553 68k is low, you can call Ford customer support about it after your diagnosis
@@BigBensCarsAndCycles The wait time just for a diagnosis is over 3 weeks..and ppl say the repair time is actually taking up to 3 months. I decided to just get a new tranny put in for about that same cost as FORD, and other mechanics were saying it would cost to replace the CDF drum, and other parts. Thanks for the videos!
What is the cost for this type repair.
I would say roughly 4500 dollars
Is there a difference between the 10R80 RWD and 4WD?
Was this F-150 a 4WD? Approximately; how much time does this repair take to do?
My truck is a 2019 F-150 4WD STX with a 10R80.
No difference between 4 and 2 on the internals. Cdf job took me 2 days. That's with removing and installing the trans too
Nice breakdown of the 10R80!
Is this problem more on f150's or mustangs also? Even tho the transmission is the same
More so on trucks. I've only seen 1 on a mustang
@@BigBensCarsAndCycles interesting.... I wonder what the big difference is for causation... 🤔
@@100pyatt The trucks are heavier and tow/haul stuff
Right on. When that ring rolls off and it's stuck. We know what happened. Do a 8F35 hatespeed next.
@Indiana_Golden hi, thanks. I have a video on an 8 speed already, check it out 👍
Very interesting seeing inside the 10 speed transmission. Thank you.
I have a 2018 F-150, 54K. What is the likelyhood of having the CDF failure.
It's very common. If you have loss of engagement of extremely delayed shifts then likely
Took my truck to the dealer for a flare from 3 to 4 when the transmission is cool. They're doing the valve body first because ford won't pay to do the CDF drum from the start. Why would ford want to do that first if the issue is obvious?
Since I don't work there anymore, I'll be honest - if it's obviously the CDF drum I went straight there
So there is no drain plug on the oil pan. WTF?
Looks like a guy in his garage could get this done. Awesome video Big Ben, thank you.
You're welcome! Make sure you get the #3 sun shaft fully seated in the cdf drum, take pics first If you want to.
Where are you located?
If there is a problem is there also metal in the pan when you service it. I’m at 51,000 on my 2018
Hi, it's rare for a cdf failure to cause metal in fluid
Plastic transmission pan😵💫
Wow, am I happy the DPS6 is nowhere near as complicated as this thing!!!
Yes sir! 👍
The only real reason for so many gears, I'm sure, is that some of those are very low gears, for towing/etc, right? @@BigBensCarsAndCycles
@DetroitMicroSound none of them are granny gears like that. There's just lots of gears to choose from for ideal rpm for different driving situations. The pcm will actually skip several of the gears during normal light driving. Around town it'll go 1-3, then either 3-4 or 3-5 depending on throttle and load
Interesting. But weren't F150 drivers happy the old way? 😉@@BigBensCarsAndCycles
@@DetroitMicroSound I like the 6 speeds better for sure! Smoother and more simple & reliable
The garbage can had major wear the grooves are supposed to be completely smooth and if not replaced can wear all the way through down the road and I’ve seen it. It’s easy to rewind and pause and see the grooves in them. Can definitely needs to replaced especially for aggressive drives.
I noticed that after uploading, it ended up getting the garbage can. Thanks for pointing that out, I need to make a note of that
What causes surging in 3 4 5?
That can be caused by the cdf failure. If its just firm shifts, its normal. If it is a strong delay, then CDF
@@BigBensCarsAndCycles no so much delay as after each they surging. Maybe engine control issue.
I have a 23 NA v6. Company vehicle. Like my 15 5.0 6r80 better. Both f150
My 2020 F-150 had a transmission failure at 74k miles. Luckily I have the extended warranty and it is currently being overhauled by the dealership. Is there a difference in the type of overhaul a Ford dealership does on the 10R80 based on a Warranty repair vs a non warranty repair?
Hi, in my personal experience, with a customer paid repair I may recommend replacing the valve body in addition to the internal repair. That will ensure smooth shifts and won't be a gamble
absolute BS that this is such a common and k nown issue and yet ford wouldn't cover it.
Are 2022 Ford Transit 350 AWD HR transmission included. You did not mention it. Thank you…
2022 is getting to where they started implementing the redesigned drum at the factory. I'd have to run your vin to see.
@@BigBensCarsAndCycles 1FTBW2XG5NKA35862
My transmission does the same thing. Almost goes away completely when warm. Except 8th gear shifts a little hard. Do you think this is most likely my problem? Also where can I order parts? And where can I find parts diagram with part numbers for internals. Thanks in advance.
Hi, harsh 7 to 8 usually is fixed with a new valve body. Strong delay into 2, 4 or 6 when cold is usually a cdf issue. Ford has a tsb for the cdf drum you can print out. Base part number is 7h451 I believe
@@BigBensCarsAndCycles great so you’re telling me i may have both issues lol. I sourced out a new cdf drum. Looks like I can get a new drum assembly for 189$ Do you know how much a new valve body is? And yes you’re correct it’s always gear 7 to 8 that’s harsh.
@@TheTechGuider If you want to join my discord I can list some parts for you, theres a lot
@@BigBensCarsAndCycles also my f150 has the 5.0. Idk if that makes a difference.
@@BigBensCarsAndCycles yeah I have a discord account.
How do the vehicles drive after installing the new CDF drum? My truck is at the dealership right now, waiting for this part as well as a new valve.
shifted perfectly after
@@BigBensCarsAndCycles no more hard shifts? How about that cold shift between third and fourth gear?
Hey Ben. I got a question for ya. ya might not know the answer or maybe ya do. QUESTION IS. My 2022 F-150 (Built in March of 2022), just had a Complete Transmission Replacement 10R80 in SEPT, 2023. The New Tranny came from Memphis Tennessee. Would you have a Clue if the NEW Transmission would have Been Updated with the New Bushing and Stuff? I know I'am asking a Lot of ya, But I wouldn't have a Clue at all. Thanks Big Ben.
Hey! My money would be on it having the updated design CDF drum inside. I can almost guarantee
@@BigBensCarsAndCycles mine is a 2021 I bought it used from a dealerships two weeks ago. Would they have replaced this before re-selling the truck to me? It was blue certified
@@Trevormaffetone no, they would not have. It's not a recall. Sorry
@@BigBensCarsAndCycles, does the new CDF drum just have better parts or does it also have the lip on it to hold that bushing in place and prevent it from moving and causing the same damage all over again. I have read on other videos where people said when this first started happening that when the transmission was rebuilt all they did was push the existing bushing back into the proper position and put in a new set of seals. That would get you going again, but down the road it would fail again. Then I read that some independent specialty shops started fixing the problem by adding a lip to hold the bushing in place permanently. I just want to make sure Ford is doing the same thing now because my 2018 F150 transmission has failed and I can’t wait several months to have it rebuilt or replaced with a new one, so I have decided to trade mine in on a new 2023 model and hope and pray the 2023 has better parts and that lip. I love my Ford truck and really like everything about it, but that doesn’t mean anything if the transmission or engine has a catastrophic failure before 100,000 miles. If a water pump or an alternator goes out before 100,000 miles, I can live with that, but not an engine or transmission. I have never bought an extended warranty, but I think I will this time because of all the problems people are having. The only problem with that is my truck was out of warranty when my transmission broke, but even if it was under a warranty all the dealers were saying that they were behind 2 to 4 months on rebuilding these transmissions and most of the time the customer had to get a rental and continue to pay their monthly truck payment as well. I am lucky I had a backup vehicle and that bought me some time and allowed me some time to decide what to do. Thank You so much for your help!!!
@@stonecoldflipper9503 2023 and newer 10 speeds have the updated lip drum from the factory. And when they replace it on older ones they install the good one
Are you located anywhere near Ga? Mine just went in and I'm keeping my fingers crossed it's done the right way the first time.
Hi, my shop is in VA
Mine makes a terrible noise under accel around corners. Metallic and tinny like a think metal is vibrating or like a chattery clutch.
Also the 1-2 & 2-1 shift have a grinding noise. 20 mustang
If you'd like, you can take a short video of the noise and post it in my facebook or discord group
what year is this truck?
I dont remember, though it's likely between 17-22
@@BigBensCarsAndCycles Please allow me to ask two more questions. 1) If you have a record of "hard shifting" as in your dealer is aware but says it's "normal" or has tried to reset shift points etc. and then it craps out out of warranty, has ford been covering those cases?
2) What does this cost for us suckers who have had very hard downshifts, and then it finally craps out and your stuck footing the bill on your own? Obviously this will vary but are we talking 3k, 5k, 10k!?! I'm worried about my 21' that has occasional VERY hard down shift into 5th and or 3rd but only does it every once in a while.
also only 37K on my truck...
Thank you so much for this video.
So my raptor was diagnosed with this problem and I scheduled to change the drum in 2 weeks.
It is ok to drive on my old transmission for two weeks (was planning to go to different state) ?
Thanks.
@@leoblyshchyk6287 hi, if you are losing engagement while driving, I would avoid long trips. If it's just firm shifts then you're ok
Thanks for replying so quickly.
No just hard shifting and not always.
I would avoid driving it out of state. The sealing ring will eventually roll off and you will then lose other gears. I build these all the time.
How much does out of warranty repair cost?
$5k-$7k
Do you remember the mileage of this vehicle when it started happening?
No. But it can happen any time. I've seen it happen around 30k. And seen it last forever
@@BigBensCarsAndCycles thank you so much for the information
How much would it be to just do the drum? 😅
$4k or so
You sir, know your stuff, its very nice to see someone talk so eloquently through possibly the most intimidating transmission. Thank you for this, im going to possibly be replacing my output speed sensor.
I thought i was having problems on my mustang due to low fluid, got fluid changed and filled, and still got a p0721. If im in 10th sometimes and floor it, it jumps to 7 and wont shift up or down, but no wrench... Fun fun
Either way, off my soap box, thank you for the in depth video
You're welcome! Glad to help. Before you pull the valve body out, check for frayed wires on the connector on the rear right of the transmission
@@BigBensCarsAndCycles yes sir, thank you for the help!
I like your little chuckles so cute
Great video!
So are these transmissions junk ? This is a lot of work for some simple parts .
With a new cdf drum, worst case you'll have harsh shifts. Otherwise they're good
@@BigBensCarsAndCycles Does the new cdf drum eliminate this problem for happening again ? Thanks for the Reply back .
@@walkerjohnny72 It will eliminate symptoms caused by this issue. There are chances of other issues coming up with it but it's luck of the draw. the CDF drum is a common issue though.
Great Video!
Thanks!
I think most of these are caused by the EXTREMELY bad Mercon fluid Ford uses. Switching to a high quality ATF like Amsoil seems to keep these transmissions purring along 🤔
Amsoil extremely overpriced snake oil.Way overrated and big waste of money.Change more often.
Fluid was very dirty, bad preventative maintenance, vavoline is a better alternative to ulv Mercon,more robust additive package.
