UPDATE: 10 Speed Transmission ISSUES in My Mustang GT

[@DanDiMaggio]

Buddy of mine just got a 10 speed GT (basically brand new (23 6k miles) and they must have resolved these issues with the later cars. I drove his for a while the other day in a few different modes at various speeds and scenarios and it felt very smooth. I was actually seriously impressed with the transmissions performance. What really blew me away was how "smart" the transmission was in track mode with knowing when to downshift through the gears while slowing down aggressively or entering a corner. Auto's have come a long way!

[@Red5oh]

Yes aside from occasional hiccups I absolutely love the 10 speed. It's pretty response even in the paddle shifter mode. In sport plus mode it will hold the gears properly

[@calvinturton9795]

Hey bro! Did you know that letting your fuel go so low, will kill your fuel pump over time, your new empty, should be 1/4 tank. Your fuel pump is cooled by the fuel, so when you take it under 1/4, you are heating up your fuel pump, the pump is plastic, not like the old ones. Glad you got the issues fixed.

[@Red5oh]

Yes that’s a good point! I usually try to fill it up when I get the 50 to E message but sometimes I don’t get the opportunity right away

[@p4cbassman]

2023 got my transmission rebuilt per tsb. This year issue returned. Battery took a crap on me, replaced battery, all trans issues gone. Never shifted so smooth. 45k miles later….thanks Ford

[@Red5oh]

Sorry to hear that you had so many issues with the Mustang. Typically they tend to be reliable

[@KingMatt1]

You can turn off adaptive transmission learning permanently via Forscan. It’s what I did and now the transmission behaves it SHOULD without constantly trying to gear hunt or predict my driving inputs

[@Red5oh]

I did not know that! I am trying to get access to Forscan tool to play around but I am honestly scared I will mess something up lol

[@user-bk5ey9ws5g]

Nice I didn't know for scan could do that. Was your car shifting harshly as well?

[@spr3472]

I just did it, and what a difference. It is really easy.

[@oHypBasto]

Glad it fixed the issue. I am currently having an issue with my car when it shifts from 3-4 and 4-5 rough and lazy while all the other gears feel good. They did this reflash and unfortunately it didn’t fix the issue. Thinking it’s something mechanical unfortunately since I caught the dealership toying with my car with my dash cam.

[@oHypBasto]

22 10spd 5.0 with only 1400 miles. Drove perfectly before they decided to have a little fun.

[@oHypBasto]

And these issues are still apparent in even normal mode under normal driving😭

[@Red5oh]

I would definitely take it up with them since you have the dash cam footage. It's still under warranty so if they want they can get paid from Ford if they don't want to own up to their immature behavior of joy riding a customer's car. I hope your car gets fixed man!

[@oHypBasto]

@@Red5oh yes I already had a meeting with the GM and Service manager they gave me 1200 after fighting to just have them take my car back since I didn’t trust it. They denied me and wouldn’t trade me in to a similar car unless I paid an extra 7k. Now there saying they don’t want to drive the car because of what happened so if they don’t drive it to see what’s happening they can’t fix it. Going in again.

[@itsdillon1217]

Just FYI, you can change the gear selector between driving sport without stopping, same thing goes for neutral.

[@Red5oh]

Yeah I typically switch from S to D while driving. It’s really helpful instead of waiting to come to a full stop. This video I didn’t lol

[@CanyonCarver5.0]

I have the same issue. My car is at the dealership now and they didn't even know about TSB 22-2139. Service guy said they tried 3 other cars ranging from 19-22 and all had same issue. So in their conclusion, this is normal.. Hoping to get my car shifting right again because it shifts real rough and sometimes coming up the drive way it will cut out like it's having trouble catching a gear.. (22 gt w/ 5k miles on it).

[@Red5oh]

I would definitely push on the TSB or find a different dealer. 10 speed overall can be quirky due to software issues but usually is fixed by software updates or TSBs. Show them this video if you have to with the TSB performed. You can see on my original video how bad the car shakes which made the camera shake too

[@CanyonCarver5.0]

Going to call them in the morning and urge them to perform it. I've read in mustang forums too that if you reset the learning module for the automatic and drive more "safer" it will have better shifts. May try doing that too. @@Red5oh

[@tommyanderson3705]

I need to do that with mine, I have a 2018 Ecoboost at 92,000 miles it has the same harsh shifts, and now it’s slipping in 1st gear taking it to get serviced tomorrow!!!

[@Red5oh]

How did the service appointment go? Hopefully it’s an easy fix

[@xrmerkur]

Ford feelling confident issuing S650 software to the old 2019 S550 transmission. i have no idea what they really did, but glad it’s work right for you.

[@Red5oh]

Yeah some sort of a TSB but I’m glad it’s fixed. I think it’s time to tune the car

[@TheMGChannel]

Glad you got it fixed bro! We have a 2020 Expedition and we had a similar transmission issue but what it ended up happening was that the torque converter was bad. We needed up getting a brand new 10r80 by Ford under warranty.

[@Red5oh]

Thanks man I’m happy to be driving it again. That sucks your expedition needed new transmission. Good thing they covered it under warranty

[@sergiudiaconu7992]

Hi, what symptoms did the torque converter had? Thanks

[@cheekymunke]

I’m going through this right now…the gear hunting is so annoying. I’ve taken it in twice, the soft wear update was step one and they even pulled the transmission during then second visit and it still happens. My issues are between 20 and 40 MPH. I’ve had *several other cosmetic issues too. 2021 was not a good year for buying a Mustang!

[@Red5oh]

I thought from 2020+ they revised even more. If software update isn’t fixing I would push back to the dealer as it’s still under warranty

[@cheekymunke]

@@Red5oh I am…sadly I won’t have it much longer. Ford has agreed to buy it back. It’s such a bummer. I waited 20 years to buy another Mustang and now I’m too nervous to buy another one once the buyback is done with. Even my teenager says to buy a Toyota. Haha

[@Red5oh]

@@cheekymunke oh no! At least they did something about it. Typically mustangs are reliable but you must’ve gotten a lemon. If Toyota is what you then get a supra lol

[@joepisciottajr]

My car is at Palm Beach Dyno right now. Mine is lunging forward on decel. My first tune was fantastic but the second tune was horrible. Hopefully 3rd times is a charm.

[@Red5oh]

I hope they revise the tune so car is buttery smooth. I debated going to with pbd instead of lund since I have sct device but have heard their customer service isn’t great and revisions can take forever. What’s been your experience

[@joepisciottajr]

@@Red5oh well I am local to them and they did a bunch of stuff to my car. I am trying to reverse a few things the previous own did. I am actually down tuning the car. I am known at PBD as the guy who goes the opposite way, less power, less noise. Car made 770HP at the wheels. They have a bunch of tuners on hand, the dyno is pretty much occupied by Ken and Rob. However er, they have a remote tuning room that house a few tuners. They have 20 cars at the shop at all times. I was there yesterday and between them and Rarefab, had to be over 30 Mustangs. I have read up about all the tuners but for me I chose PBD because of the location. For N/A I hear PBD has that covered better than Lund. It’s a toss up with forced induction, seems peak numbers it’s PBD and better drive ability is Lund. There are some new tuners making some noise that have fast cars too. I make KZbin videos for my friends and family who are far away. Here is my car: youtube.com/@sn95mustanggarage17

[@SHADOWBLACKs650]

Go get the Ford procal 3 programmer, even better get the power pack 2 because it comes with a procal 3 programmer (and 50 lb of torque at 3000 RPM and something like 25 horsepower,) but anyway you can change the wheel circumference and that will move the shift points a little bit higher or lower, that gives you the ability to change slightly where the transmission shifts ,however you will find that the computer reflash with the power pack 2 is spot-on, unbelievably perfect and more horsepower and it calms the transmission down from shifting, it's actually how the car should have come from Ford... I've got two videos if you care to look at them with a dragy, but if all you have are occasional clunking leave it alone you have a 500 horsepower engine, the Transmissions not for a Lincoln.

[@Red5oh]

Yes I am looking to tune my car now and a lot of people have recommended ford's power pack for 10 speed as it really helps with shifting. It seems like it may not have the most power compared to Lund, PBD, etc. but it is one of the best tune especially for daily drivability. I will check out your videos on it

[@SHADOWBLACKs650]

@Red5oh don't even consider Lund, that douchebag says he hates Ford everyday on his little KZbin station, does his Tunes under a 15 watt light bulb in his spare bedroom down in St Andrews apartments in Florida, definitely stay with the people that made the car, the power pack 2 is definitely the way to go.

[@hunterkrisman6240]

Just got a 2018 about a month ago with 50k miles. Doing the same thing yours was hard “jerk” when going from R to D & only in sport mode is it doing a hard shift just like gears 3 to 5 but smooth in regular drive. Might have to get get it serviced and see if it needs a software update like yours. Wish I woulda tested S mode when I test drived it 🫠

[@Red5oh]

Ask the dealer for software update sometimes they can do it for free even if out of warranty or at most $100. It’s worth to not deal with the 10 speed jerkiness at times which really takes away from the car

[@hunterkrisman6240]

@@Red5oh for sure I will reply with how it turns out

[@jemecarlos5555]

I have a 2022 EcoBoost with the same issue. I updated the software, but after a while, it's the same or even worse!

[@Red5oh]

Did you take it to the dealer? They can reset the software for you and update. If nothing works they should be able to properly diagnose it

[@jemecarlos5555]

Sadly, I’m from Iraq, and I bought the car from the USA. The dealer here is responsible for Ford vehicles designed for the Middle East, which sounds a bit odd. However, I had it updated at a mechanic’s shop using a Ford scan tool. I believe there was a transmission update available, but they only updated the TCM or PCM (I don’t remember exactly). Now, it’s worse than before. Even when I put it in reverse, it jerks, and you can really feel it!

[@joelhernandez4863]

My car is having similar issues . When on sport mode from 2nd gear to 3rd it shift way to hard, to where it shakes the whole car.

[@Red5oh]

Yeah this 10 speed has some software issues. If it’s still under warranty I would take it in to the dealer so they can perform a TSB

I will check to see if I still have the receipt so I can post the tsb to help others out. But yeah I recommend taking it to the dealer and have them perform software update and check for any TSBs available

So would u say that a 2019 isn’t worth it. I currently have a 2023 mt82 and I’m looking for a 10r80 and the ones around me from 2020-2023 have like 15k miles and over priced. Yesterday I found a 2019 with 5k miles and I was interested but after watching this video I’m scared of getting it. So I wanted to know your opinion. Also I heard about oil consumption issues ?

[@Red5oh]

No oil consumption issues. As for transmission it’s mostly software updates no hardware related issues so I wouldn’t be worried about it. As long as the test drive is fine you’ll be ok. 2021 and up got slightly updated software but I wouldn’t knock out 2019

Interesting. Which TSB is it? My 10sp (2018) can be brutal in gear changes, particularly in D. Think I’ll call my dealer tomorrow and see if this is something they can apply. Mine isn’t under warranty, so would I need to pay??

It was TSB 22-2139. TSB should be free from what I recall. I would call the dealer to confirm

[@NighthawkCarbine]

My 2020 Mustang GT 10 speed tranny has been 100% trouble free.

Yeah ford updated the strategy around 2020 which made it smoother. Mine is fixed for now but I think I’ll tune it to make it shift better

im having the same issue with my 2022 musatng gt they said it was normal only have 3k miles. idk what to do. also in sport it hesitates to go into 2nd gear

[@berni303]

How did it end? My 2020 leaps when shifts into 3rd and shakes when downshifts into 3rd. :|

[@Red5oh]

They did the update. It has been fine since. Since yours is under warranty I would recommend the same

[@dack6i9]

I had the same issue on my 2019 GT. After multiple visits, local dealers are so convinced that this is normal behavior unfortunately; however, I just took it to a ford transmission shop with Forscan. A simple adaptive learning reset magically resolved my issue. My issue previously was most noticeable on 2-3 specifically, which is almost impossible to recreate in drive (not sport) unless it’s in wet mode.

Depending on the mods you can return to stock then have them update the software
