Great video. I've been having the same problem with my 2019 F150's 10 speed transmission. Just got it back from my local Ford dealer (Northern Virginia) today, where it underwent a complete overhaul. Hopefully it solved the issue. By the way, I was happy and surprised to see the location of your video. It's my old hometown. I recognized everyplace you went in it. In addition to an informative video you made me feel homesick!
great content! my 21 f150 47,000 miles has a harsh shift from 1 to 3 on very lite acceleration worse on colder days like pulling out of the drive way first thing in the morning. Also on several occasions when cold it actually down shifted with a few flares when coming to a stop and then remained in 10th gear at a dead stop and would not pull like it was actually hung up in 10th gear I had to shut off engine shift from park to reverse and it then went into 3rd and was able to pull off then once its up to 1/2 way on trans temp gauge it shifts like a dream. I've had it at local dealer twice first time reset the adaptive shift tables and came back quickly and after 3 week wait to get it back in and they did the same with a reprogram and a performed a "sticking valve procedure"??? that was the best its ever shifted for about a month, now same but not as harsh as before on the 1-3 on light acceleration only when trans is cold and no hanging in gear but after everything is up temp shifts near prefect.
Saw you actually responding so I thought I’d give it a try. I have a 2019 F150 and on a road trip recently, it overheated and ford said it was 2 quarts over filled. A couple weeks after that, it is now slamming into gear going 3-5 and VERY delayed when going 3-4 to where it throws my body forward before finally catching the gear. I am thinking the valve body is now damaged but wanted to shoot my shot on what your thoughts were or if you diagnosed these symptoms before. More apparent after a cold start and every other gear shifts perfectly up or down as well.
In my 2020 GT, after connecting forscan, I see many options, including "halt adaptive transmission learning". Maybe this is a long-term solution to the problem after finish procedure of adaptive transmission learning.
Hello, i have a 2019 mustang gtcs with the 10r80 61k miles. I had rough shifts cold 4th gear shift issue and cluncky on downshifts to a stop. I had ford do the updated cdf service thank god under warranty. Told me it was 8k. Since then ive had increasing problems. Overheating to over 230 degrees and once a wrech light came on and car wouldnt let me shift, afte4 spirited driving. Let it sit a few and it drove home fine. I still have cluncky downshifts coming up to a stop and sometimes thumps hard into 1st. Any idea? Im out of warranty now and very concerned. Appreciate any feedback immensly.
Thanks for your video and insight. I have a 19/MY20 Mustang GT with the 10R80 in Australia. Dealer has diagnosed issues with the transmission and presented the TSB24-2101 (harsh/delayed shift) and 20-2198 (high pitched whine for cars built Oct-Dec 19 which mine is) to Ford AU for repair. However, Ford AU denied any repairs to be performed on vehicle even though it is still within warranty. Ford AU even say the TSBs don't apply in Australia, even though they're the same 'box and have the same problems as any other Mustang in the world with a 10R80!! The whine is self explanatory and accords with TSB (TSB fix would include the replacement of the transmission inner output shaft bearing). The harsh shifts are mostly in Sport and while unpredictable, revolve mostly around 2-3-4. In normal mode, a kick-down at 80kph 10-8 is always rough. What would your prognosis of this transmission be? Dealer would have done any software updates at recent service. Would a full replacement transmission or could a transmission expert actually pull this one apart and fix? Any thoughts appreciated!
Oh wow. All I can say is, if the transmission is still broken and under warranty you'll have to tell them you want to have it repaired. They can't give you the car back that way
@@BigBensCarsAndCycles thanks for your response. Yes, so the problem is they have given me the car back that way. It seems my only avenue is a legal proceeding as I don’t know the long term durability of the transmission with these faults.
Hey there! Thank you for this video. I bought a 61k mile ‘21 Expedition Max and noticed that it would jerk violently at times when going from park to drive (or to reverse). Is this something I should worry about or have checked? I have also observed some jerking when downshifting from 4th to 3rd but I’m not as worried about that. Appreciate it!
Hi, If you bought it from a ford dealer you can talk to the salesman if there's no extended warranty. Otherwise if you have no warranty, I would live with it. Don't worry unless you lose engagement during upshifts (typically 3 to 4th) then rebuild or replace
I would love to get your opinion on these if you have the time! Just got a 2021 Mustang Gt with only 6,000 miles on it, got the 10r80 in it. Really hard 1-3 and 3-5 shifts. in sport + all the shifts are pretty jerky even when the trans temp is 200. Seems to have trouble finding drive again after backing up (R to D). Downshifted from 10-9 the other day as i slightly got on it to pass someone and it seemed to take a second to be fully set in 9th gear. It is 30 degrees here but I always let everything warm up before even getting on it. Car is under full warranty but dealership told me it’d be at least a week and I’m under 25 and can’t get a rental. Should I attempt a KAM reset if I can do that myself? Or just book another appointment and wait it out? Any advice is greatly appreciated!
Hi! These are clunky and firm transmissions. Sounds like somethings a bit abnormal. You can have the dealer overhaul the valve body, and if that doesn't fix the long delay 10-9 you may need a new cdf drum
I just bought a 2019 f150 off a lot in salt lake city. 3.5 ecoboost. Soon after i left my trip on my way back home, i noticed some delay shifting between 3-4, 3-5 and 9-10. I just kind of ignored it thinking it was adapting. About 700 miles into my trip home it starts to go haywire with all sorts of things and then ultimately shuts everything down. I pull over put in park then in gear and nothing. Turn the truck off then back on, put in gear and it starts to go, tries shifting into 2 and 3 with lots of shuttering and delay. The dealership (not ford)i bought from wants nothing to do with helping me fix it, ford dealerships were a joke to talk to and now i have a $31k "brand new" truck sitting in my driveway that needs transmission work and not even sure yet what it is, when it can get fixed and how much. I have seen there is a lawsuit on ford for these year transmissions, sounds like theyve had nothing but issues. IMO , ford corporate should be paying for this
Hello, I enjoyed your videos on 10R80 transmission and wanted to try my luck on what your thoughts would be on the issue that I have with mine. I have a 2021 Ford Expedition with about 25K miles, no warranty. Upshifting is more or less normal. Morning shifts to either rear or drive on the cold start are jerky. Worst part, while downshifting, starting from 4th gear going down till a complete stop it hesitates, jerks, always skips the 2nd gear on the gear indicator, and most of the time (not always) it give me this "thump" or a "bang" as I am almost getting to a complete stop. My local Ford dealer says they performed TSB 22-2428 and performed adaptive learning drive cycle, did not help at all. Please reply with your thoughts on this or if you came across or diagnosed these symptoms before. Also, where are you located if I were to bring it in for a fix.
Hello, thanks for watching. I know it's normal to skip 2nd on upshift, and I'm fairly certain it is on downshifts as well. I'm not at work at the moment. Based on your symptoms it may be a valve body issue. It's possible your cdf bushing has moved as well. I'd have to get a better feel for it in person. Regardless, since there's no warranty, you'll have 2 choices next following the tsb. Take the valve body apart and clean it, replace the gaskets and see if that takes care of the issue. Unfortunately if it doesn't take care of it, you'd have to pay for more labor to go back in and either replace the valve body or cdf drum, depending on what the tech believes is the next logical step. I'm in Virginia if you decide to come. Thanks!
Hi@@BigBensCarsAndCycles , and thank you for your reply, i feel like I would definitely need help on my trany as it gets worth with more miles. I wonder do you handle transmissions privately at your own shop as well ? or just at work at the dealer ? If you do - are the replacement parts easily available ? and how long a repair like this might take ? Please, let me know as I am thinking of bringing it to VA and wait for it to take it back. If it is easier for you - we can chat directly, just give instructions. Thank you in advance
I have a mustang with the 10r80 that has jerky shifting, just now learning of the cdf drum sliding, what’s causing it to actually slide down? And isn’t it just going to happen to the new drum eventually? I have jerky shifting the odd time but the most persistent is a really big lunge when you downshift 3-2 above 30kmh (10-15mph?)using the paddles. No software updates/tunes have been able to remedy it so far
You could have a sticking valve or solenoid. I've only seen 1 cdf bushing shift on a mustang. It seems to be an issue with larger vehicles, but can happen.
Figured I'd ask you a question since you've been very responsive on other comments. Greatly appreciate your insight. Bought a used 17' f150 raptor and it has a rough downshift only in gears 4 to 3 when cold. Is that pertaining to the CDF drum? Can hear a mechanical clunk every time it downshifts from 4th gear into 3rd. Eventually goes away after we've been driving for 10-15 minutes.
Hey, I'm leaning towards a sticking valve or solenoid. That's at least a good place to start. Service bulletin 23-2250 applies here. Does it just jerk a little? If it has a strong lag or delay then yes the cdf drum. If it's just a bump, valve body
@@BigBensCarsAndCycles yeah no lag or delay. Just a solid thud like the gear is hinging on something before it goes down into 3rd. Also have experience a highway confusion where you floor it to pass a semi on a one lane road and the transmission would thud really loud on the downshift shift, lose power for a sec, then resume accelerating like nothing happened. I swear it felt like the transmission exploded. Dealership here in town has a waiting list to schedule an appointment with a transmission specialist. So just trying to narrow things down and figure out if its even worth taking it in. Truck still drives fine.
I just passed the warranty mark with my 2019 F150, and after seeing these issues I might get rid of it. It's had a flare between 3-4 when cold since new. I don't want to risk it and have to come out of pocket $4500-7000 for a truck that doesn't even have 100k miles. This was my dream truck. My dad sold Ford's and I have owned 4 of them but this might be my last.
2023 and newer have the updated cdf drum from the factory. They can still get firm shifts but it's no big deal and can be mitigated with a scan tool (accelerated break in procedure)
Hey man, just purchased a 2018 F150 with the 5.0L and 10 speed transmission. It shifts perfectly fine cold, but when the trans warms up to 190 F it has a hard shift from 1st to 3rd. Only does this when it’s warmed up to 180-190 F. Thoughts?
I made an appointment for tomorrow for my 18 f150. This issue is really stressing me out. I saw this video of yours and got me relieved a little bit, hopefully it’s not seriously bad. Wrench icon pop out and can’t get rid of it. Any idea what could cause this? I appreciate it.
You're welcome. You're not the only one. The techs have experience with these. The wrench light could be transmission related. You may need the cdf drum. Being a 2018, you may be out of warranty.
@@BigBensCarsAndCycles gotcha., it started doing hard shifts between 1-3-4-5. About a week ago I didn’t really payed attention to it because it will run fine as soon as it gets warm enough. Now started harsh 9-10 and would go back to 1 when it feels not going to make it to 10. I got a service agreement and im not sure if that’s covered from it.
Hey man, I have a 22 f150 with about 57k that has recently started to not engage all the way when I go into reverse. Sometimes it will but most of the time it takes a few seconds and a message on the dash says “gear will engage at low speeds” and then it kicks and grabs. Im planning on getting her checked out but just figured I’d see what you think. Downshifts from 4th to 3rd have also started to get very rough to. Not sure if it’s related to the reverse or not.
@@BigBensCarsAndCycleswell I got a call back from the dealer. They are replacing the valve body and something else. Thankfully I was within my 60k warranty by about 1500 miles…. Phew 😅
I have a 2020 ford ranger, with the 10r80. I do have a question, why is it when i have my foot on the gas very slighty, barely even giving it gas, then when it downshifts it slams into the gear? It seems to slam into gear when doing certain things... Its any gear when youre barely on the gas and it downshifts .
All i can say is you can have it looked at for free if you're still under warranty. Your transmission shouldn't slam hard in gear from a certain way you drive.
Currently looking for a 2018 and up Mustang GT Auto, but every single one I have test drove likes to give a harsh kick after flooring it feels like your being rear ended. Will software update fix that?
I have a 2020 f150 it will only have a delay/hard shift into 4-5 when it is warm. And will hold gears when coming to a stop. Are those symptoms of a bad cdf drum? I have had it in before for the reprogramming.
Hey I have a question about the relearn process. I read alot of comments about peoples transmission shifting harsh in sport mode, can you do the relearn process in sport mode to prevent possible harsh shifts in that mode? Or is it better to do the whole process after you reset the adaptive learning in the regular mode in hopes sport mode doesn’t have harsh shifts as well?
Hi, it's simple enough to do a relearn. You can try doing the relearn in sport mode and see how it does. In general, sport mode is going to be more firm than regular mode in nature. But if its slamming thats an issue
What is your opinion on my situation? I have an 18' F-150 with 86k, at 82k the transmission, cooler, lines etc was replaced due to a hard shift 3 months ago. Experiencing intermittent hard shifts again. If you floor it the transmission will bang into gear, or if you drive in tow haul it'll bang on downshifts. Otherwise it drives normally with the occasional hard shift. Ford has diagnosed it and they want to drop the trans and see if the CDF drum is an issue. Last transmission replacement took over a month, based on your expertise, should I have the transmission dropped again and looked at. its all under Ford Warranty, BUT I am out of a vehicle for an unknown amount of time. Or is it likely to continue regardless, and just not worry about it and live with the truck driving terribly?
Hi, I see where you said you had the transmission replaced 3 months ago. Was that a warranty repair? If so, the new transmission has a 12 month 12k mile warranty. If you paid for the transmission, it will have a 3 year unlimited mileage warranty. I would let them replace the cdf drum. They will install the updated design drum, which will let you have plenty of worry free miles. That's the only part I've seen lead to stranding someone on the side of the road (inside the 10 speed). You'll still get some firm shifts due to the valve body. But it should improve. Don't worry about firm shifts from the valve body too much. There isn't much you can do about that as far as a permanent repair. You can bring it up to them later if it still shifts firm after cdf drum replacement, and they'll reprogram the strategy and replace the valve body gaskets. That usually helps mitigate firm shifts from the valve body
@@BigBensCarsAndCycles Thanks for the input. Yeah it was customer pay, so it has the 3yr warranty. In your experience how long does it take to replace the CDF drum? My dealer isn't being too helpful with giving me an estimated timeline, but I just want to prepare myself for being out of a vehicle. The transmission replacement the dealer did back in May of 2023 (3,000 miles ago) took from 4/19/2023 - 5/26/2023. They have me scheduled to bring it in for tear down on 10/3/23. Man, did I wish I had firm shifts. My occasional hard shifts feel like someone just rear ended the truck. Or if I am climbing a hill with moderate throttle and it downshifts to 8, it feels like the transmission is going to rip off underneath.
@abfilio1 It depends on parts availability. Likely your transmission was a few weeks away. It may be quicker this time. I'd let them diagnose it and order parts, then they will have a better idea of a time frame. To be safe, you may just expect the same time frame, if you are trying to plan it out.
Hey man one more question. When I stop slow my transmission in sport mode only seems to skip 2nd gear. But when I stop very quickly in high gears it seems to down shift in intervals. Like from 9 to 7 to 5 to 3 to 1. What’s up with this is that normal? The engine doesn’t seem to sounds strange when doing it. I just concerns me.
I have a 2019 from day one it would hesitate and cluck going into 3-4-5 …..only when cold ….they told me it’s normal…I’m just finding out that it could be something I’m out of warranty I have 62000 miles on it …is it still covered?
No, you're not covered. Unless you have an extended warranty. Ford may come out with something for people like you since this is super common. But either way, firm shifts won't hurt it. If it's setting a wrench light with incorrect gear ratio codes then yes get it looked at
@@BigBensCarsAndCycles that really sucks …it’s done it from day one and hasn’t gotten worse, when cold it slips going from 3 to 4-5 and and sometimes hard shifts……is this something I should be saving up for ….will it eventually leave me stranded and how much to fix? $$$$
Trust me! There are thousands of us out there just like you that got told “ it’s normal characteristics “ of this 10r80 2017/2018/2019 etc and now 5-6 yrs later and out of warranty all this comes out now! Ford is really screwing a ton of people, i own 2 and have zero long term ownership confidence which is sad!
@@jasonguidry6449 100% I remember 4 years ago at the dealership test driving my truck and it did it out of the lot and they told me “ ohhh it’s normal …. It needs to get up to temp “ ..i told the sales man “ that’s BS I want to drive another one and see “ I drove the 5.0l and I swear on my mom that freaking thing shifted the same way ….it shifted out of third and fell flat on its face …I had to believe it was normal!?!?!
Waching videos like this only confirms that i will only buy a car with a lifetime powertrain warranty to cover defects that the manufacturer refuses to cover past certain miles
@@BigBensCarsAndCycles with the TSB being out there before I bought the truck I’m hoping they already did it. I do have a warranty still. I’m going to ask them if they did this. If not I’m going to try and force them do replace the CDF
@@BigBensCarsAndCycles okay so if I go in and complain about weird shifting they will just say it’s normal. I’d have to come out of pocket unless it fails. Dang it lol Thanks for your help man.

Might be time for the cdf and inspection inside
I have the same problems as you, that's how I found the fault??
2018 Expedition, I have a 1-3 harsh cold upshift, and have a random delay 7-8 upshift. I've noticed it on colder temps as well.
Most likely a valve body concern. Thanks for watching!
@@BigBensCarsAndCycles Much appreciated bud. Thanks for the quick response and the good content.

A very delayed 3-4 upshift when cold is textbook symptoms of a shifted cdf drum bushing. I don't believe it being overfilled caused that.

Also have experience a highway confusion where you floor it to pass a semi on a one lane road and the transmission would thud really loud on the downshift shift, lose power for a sec, then resume accelerating like nothing happened. I swear it felt like the transmission exploded. Dealership here in town has a waiting list to schedule an appointment with a transmission specialist. So just trying to narrow things down and figure out if its even worth taking it in. Truck still drives fine.
@@RobCross-gm7wd Gotcha. You may end up needing the drum. They may want to start with cleaning or replacing the valve body first.
I just passed the warranty mark with my 2019 F150, and after seeing these issues I might get rid of it. It's had a flare between 3-4 when cold since new. I don't want to risk it and have to come out of pocket $4500-7000 for a truck that doesn't even have 100k miles. This was my dream truck. My dad sold Ford's and I have owned 4 of them but this might be my last.
Good idea 👍
@BigBensCarsAndCycles My Father in law has a 2018 F250. Are the transmissions in the super duties holding up?
Also do you believe the 21 to 24 model 10r80s are still having the same problems? Thanks for the videos.
2023 and newer have the updated cdf drum from the factory. They can still get firm shifts but it's no big deal and can be mitigated with a scan tool (accelerated break in procedure)
Hey man, just purchased a 2018 F150 with the 5.0L and 10 speed transmission. It shifts perfectly fine cold, but when the trans warms up to 190 F it has a hard shift from 1st to 3rd. Only does this when it’s warmed up to 180-190 F. Thoughts?
My thoughts are that replacing the valve body should fix that
I made an appointment for tomorrow for my 18 f150. This issue is really stressing me out.
I saw this video of yours and got me relieved a little bit, hopefully it’s not seriously bad.
Wrench icon pop out and can’t get rid of it. Any idea what could cause this? I appreciate it.
You're welcome. You're not the only one. The techs have experience with these. The wrench light could be transmission related. You may need the cdf drum. Being a 2018, you may be out of warranty.
@@BigBensCarsAndCycles gotcha., it started doing hard shifts between 1-3-4-5. About a week ago I didn’t really payed attention to it because it will run fine as soon as it gets warm enough. Now started harsh 9-10 and would go back to 1 when it feels not going to make it to 10.
I got a service agreement and im not sure if that’s covered from it.
@@acclem3026 best of luck to you. It does sound like a shifted cdf bushing
Hey man, I have a 22 f150 with about 57k that has recently started to not engage all the way when I go into reverse. Sometimes it will but most of the time it takes a few seconds and a message on the dash says “gear will engage at low speeds” and then it kicks and grabs. Im planning on getting her checked out but just figured I’d see what you think. Downshifts from 4th to 3rd have also started to get very rough to. Not sure if it’s related to the reverse or not.
That could be an output shaft speed sensor going bad (making the pcm think the vehicle is moving)
@@BigBensCarsAndCycleswell I got a call back from the dealer. They are replacing the valve body and something else. Thankfully I was within my 60k warranty by about 1500 miles…. Phew 😅
I have a 2020 ford ranger, with the 10r80. I do have a question, why is it when i have my foot on the gas very slighty, barely even giving it gas, then when it downshifts it slams into the gear? It seems to slam into gear when doing certain things... Its any gear when youre barely on the gas and it downshifts .
All i can say is you can have it looked at for free if you're still under warranty. Your transmission shouldn't slam hard in gear from a certain way you drive.
Currently looking for a 2018 and up Mustang GT Auto, but every single one I have test drove likes to give a harsh kick after flooring it feels like your being rear ended. Will software update fix that?
It should help at least. After programming, further work may be required to inspect the valve body. Cdf bushing failures are less common on mustangs
I have a 2020 f150 it will only have a delay/hard shift into 4-5 when it is warm. And will hold gears when coming to a stop. Are those symptoms of a bad cdf drum? I have had it in before for the reprogramming.
Most 10 speeds that I drive will shift firm into 5th when warm. And no, I've put a cdf in one for something else and it still did that after.
Hey I have a question about the relearn process. I read alot of comments about peoples transmission shifting harsh in sport mode, can you do the relearn process in sport mode to prevent possible harsh shifts in that mode? Or is it better to do the whole process after you reset the adaptive learning in the regular mode in hopes sport mode doesn’t have harsh shifts as well?
Hi, it's simple enough to do a relearn. You can try doing the relearn in sport mode and see how it does. In general, sport mode is going to be more firm than regular mode in nature. But if its slamming thats an issue
Hi, if you do the adaptation in sports mode, let me know how it went. GT 2020 here 🤟
Hi I have a 2020 f150 and going some 7-8 is very harsh sometimes it feels like I got rear ended. What issue could this be? I’m still under warranty
I suspect a sticking valve in the valve body.
What is your opinion on my situation? I have an 18' F-150 with 86k, at 82k the transmission, cooler, lines etc was replaced due to a hard shift 3 months ago. Experiencing intermittent hard shifts again. If you floor it the transmission will bang into gear, or if you drive in tow haul it'll bang on downshifts. Otherwise it drives normally with the occasional hard shift. Ford has diagnosed it and they want to drop the trans and see if the CDF drum is an issue. Last transmission replacement took over a month, based on your expertise, should I have the transmission dropped again and looked at. its all under Ford Warranty, BUT I am out of a vehicle for an unknown amount of time. Or is it likely to continue regardless, and just not worry about it and live with the truck driving terribly?
Hi, I see where you said you had the transmission replaced 3 months ago. Was that a warranty repair? If so, the new transmission has a 12 month 12k mile warranty. If you paid for the transmission, it will have a 3 year unlimited mileage warranty. I would let them replace the cdf drum. They will install the updated design drum, which will let you have plenty of worry free miles. That's the only part I've seen lead to stranding someone on the side of the road (inside the 10 speed). You'll still get some firm shifts due to the valve body. But it should improve. Don't worry about firm shifts from the valve body too much. There isn't much you can do about that as far as a permanent repair. You can bring it up to them later if it still shifts firm after cdf drum replacement, and they'll reprogram the strategy and replace the valve body gaskets. That usually helps mitigate firm shifts from the valve body
@@BigBensCarsAndCycles Thanks for the input. Yeah it was customer pay, so it has the 3yr warranty. In your experience how long does it take to replace the CDF drum? My dealer isn't being too helpful with giving me an estimated timeline, but I just want to prepare myself for being out of a vehicle. The transmission replacement the dealer did back in May of 2023 (3,000 miles ago) took from 4/19/2023 - 5/26/2023. They have me scheduled to bring it in for tear down on 10/3/23. Man, did I wish I had firm shifts. My occasional hard shifts feel like someone just rear ended the truck. Or if I am climbing a hill with moderate throttle and it downshifts to 8, it feels like the transmission is going to rip off underneath.
@abfilio1 It depends on parts availability. Likely your transmission was a few weeks away. It may be quicker this time. I'd let them diagnose it and order parts, then they will have a better idea of a time frame. To be safe, you may just expect the same time frame, if you are trying to plan it out.
@@BigBensCarsAndCycles Bummer, hopefully it was just a parts delay thing for the trans replacement and the CDF will be much quicker. Thanks again
Hey man one more question. When I stop slow my transmission in sport mode only seems to skip 2nd gear. But when I stop very quickly in high gears it seems to down shift in intervals. Like from 9 to 7 to 5 to 3 to 1. What’s up with this is that normal? The engine doesn’t seem to sounds strange when doing it. I just concerns me.
Hi, it's normal for a 10 speed to skip gears
@@BigBensCarsAndCycles thanks man. Really appreciate the prompt replies. Will point my family ford owners to sub to your channel
I have a 2019 from day one it would hesitate and cluck going into 3-4-5 …..only when cold ….they told me it’s normal…I’m just finding out that it could be something I’m out of warranty I have 62000 miles on it …is it still covered?
No, you're not covered. Unless you have an extended warranty.
Ford may come out with something for people like you since this is super common. But either way, firm shifts won't hurt it. If it's setting a wrench light with incorrect gear ratio codes then yes get it looked at
@@BigBensCarsAndCycles that really sucks …it’s done it from day one and hasn’t gotten worse, when cold it slips going from 3 to 4-5 and and sometimes hard shifts……is this something I should be saving up for ….will it eventually leave me stranded and how much to fix? $$$$
Trust me! There are thousands of us out there just like you that got told “ it’s normal characteristics “ of this 10r80 2017/2018/2019 etc and now 5-6 yrs later and out of warranty all this comes out now! Ford is really screwing a ton of people, i own 2 and have zero long term ownership confidence which is sad!
@@jasonguidry6449 100% I remember 4 years ago at the dealership test driving my truck and it did it out of the lot and they told me “ ohhh it’s normal …. It needs to get up to temp “ ..i told the sales man “ that’s BS I want to drive another one and see “ I drove the 5.0l and I swear on my mom that freaking thing shifted the same way ….it shifted out of third and fell flat on its face …I had to believe it was normal!?!?!
Waching videos like this only confirms that i will only buy a car with a lifetime powertrain warranty to cover defects that the manufacturer refuses to cover past certain miles
What do you think of the 10r80 as a transmission? Would you be concerned owning one?
On an f150, with an updated cdf drum, I'd feel fine with it
@@BigBensCarsAndCycles with the TSB being out there before I bought the truck I’m hoping they already did it. I do have a warranty still. I’m going to ask them if they did this. If not I’m going to try and force them do replace the CDF
@TrevorMaffetone they wouldn't do anything unless it's a recall. A tsb is a problem recognized by Ford and has a specified outlined repair
@@BigBensCarsAndCycles okay so if I go in and complain about weird shifting they will just say it’s normal. I’d have to come out of pocket unless it fails. Dang it lol
Thanks for your help man.
None of that is cheap only thing that is cheap is Ford's 10 speed transmission quality wise my new truck shouldn't be doing that
