Finally a Ford TSB to Try and Fix our Transmission Problems (TSB 24-2046)

[Jason B]

Hm. I have an Oct 2020 built truck with 18K miles, purchased end of March 2021. I wouldn't say it has harsh shifts, but it does sometimes like to camp out in 7th when it should be in 4th, and I tap the accelerator to get it to shift.

I just had it in the shop to replace the HVAC actuator and got it in under warranty period. Waiting on replacement parts. When I go back in I'll ask them to check out the trans.

Switch to tow mode, it will be a lot better.

I just took my 2019 in to be looked at under the 23-2350 TSB at 43K miles. They noticed that it was flashing higher RPM's then dropping when shifting 1st to 3rd. They applied to software update per the TSB, but of course made me pay for it. (I'm still not sure why as it should have been the covered.)

They said to drive it 500 miles to finish they trans re-learn process to make sure it was fixed, as the tech said it wasn't flashing anymore. I am 150 miles in and it still has the RPM flare going to 3rd. Once 500 miles are up it will be going back to be looked at again for the 2nd step of the TSB.

Just had this done at my dealer as well after having issues between 3-4 gear. Sitting right at 63K (of course, 3K over) but have an extended warranty. The service writer stated, "Don't worry, if the transmission is going bad you'd definitely have codes popping up. Just let it relearn for 500 miles and you'll be good to go." Unfortunately, I'm still getting weird shifts 400-500 miles later.

I don't have much confidence at all in getting this fixed before my warranty runs out. Really gonna start paying down my loan so if I need to ditch this truck I can without hesitation. I love it to death and nothing against Ford, but this is a nuisance with no real incentives to fix it.

I recorded multiple videos off it still doing it and will be taking mine back in a few weeks and see what they come up with. I will update on here when I do.

Had my battery replaced recently and my transmission was hanging on gears way too long. Felt like I had no torque. Drove this way for a while then it just cleared up. 2019, transmission has otherwise always been incredibly smooth and peppy. I would buy another Ranger.

I have the Livernois tune, and mine behaves much like yours. When it's cold, the first couple of shifts in the morning can be a little rough, but then it's fine. Been doing that since new.

I’m also running the Livernois tune. I run the towing tune just about all the time. I got tired of swapping back and forth all the time.

So a really common problem I'm seeing with all of our rangers is ROUGH and Delayed clunky shifting. I'm also seeing that alot of ranger owners have to replace their transmissions before they reach 100K miles. This sucks. You can bet this harsh delay and clunky shifting is a contributing factor to the short life span of our transmission

A brand new technical service bulletin (TSB 24-2046 ) was just released a few days ago on February 22, 2024.

Title: 10R80 Automatic Transmission - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift - Non-Main Control Break-In Capable

Issue: Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift. This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve. To correct the condition, follow the Service Procedure to identify and correct the condition.

I've attached the TSB document for you to see but to me, it looks like a BUNCH of work on the transmission. There's even some language for newer/low mile vehicles to have a complete transmission replacement. Not some little gasket or plug and play replacement. Someone smarter than me can look at it.

How do we know if we have the " 10R80 Automatic Transmission " specific transmission? I have a 2021 Ranger Lariat Tremor.

All 2019-2023 Rangers have the 10R80

Thank you. I presume not all trucks are having this issue. So far so good here.

I have a 2019 with less than 18k.

I have noticed that on rare occasion I will get a harsh shift when first starting out in cold weather. If the truck is given time to warm up in the driveway then there is no issue.

I avoid the issue by driving it mildly for the first few miles.

Once warmed up then everything is fine.

So where do I sit in regards to this TSB?

How would one get the dealer to do this TSB?

Is it true that the tranny can throw a code and not illuminate the CEL? And so the TSB is for dealers to check for codes, even if you are not having any significant symptoms?

Checking for codes is part of the diagnostic steps but having a code(s) is not mandatory to proceed with the TSB.

Tell them you are having harsh shifts and want it checked out. If you have a good dealer then they’ll know what to do

So you need to have a symptom to have them apply the TSB? Or should they just check for 'hidden' codes?

Either one of those codes or a listed symptom or a combination of both.

and they are not hidden codes, they can be viewed with a scan tool - history codes.
If the check light is not illuminated, then it is possible to still have a failure code logged into history.
You can see this with Forscan as well.

By hidden, I just meant that a CEL is not illuminated. And will they check for them if acting upon the TSB.
