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

[ambit]

Quick glance at the 24-2046 shows it to read pretty much exactly as 23-2350 with updates to wording for following procedure steps. But no big changes from 23-2350 that’s been out since November of 2023

It looks like 24-2046 makes the NEW CDF cylinder/ basket revision JR3Z-7H351-B mandatory?
Mine was in 4 weeks ago for 23-2350, got the old CDF and already had problems AGAIN.

EDIT
My mistake, JR3Z-7H351-B was installed for me on 1/22/2024, then it broke down again and had to be towed in 2/18/2024 with DTC P0766, Clutch Valve D was replaced. Truck still not 'right'.

It is nice to have a copy of the TSB's when talking to service folks...

I look at going to the dealer like working with the government - everything has a policy and procedure, if you know the key words to say you can get anything done.

I gotta take mine in for it's last free oil change, and I'm going to have them replace the cracked parking brake boot and look at the trans while it's there... <20k miles and ~14 months old...

Even with the previous TSB, you should still have the revised drum, I think your issue now was just a new failed part or installation error, on the valve body, I would have to check side by side comparison but the diagnostic procedure looks to be exact same as far as what gets replaced, some of the steps of the maintenance procedure look modified.
As with my truck - build date 8/16/22, I appear to have the new drum part number since this date is a decision point on the fault tree.
No issues with mine with 11,500 on the OD but purchased the extended warranty as a precaution and monitoring for any abnormal symptoms.
So the way I see it all builds or repairs after 8/16/22 will have the new drum installed, I cannot see a repair where they would knowingly install a known defective part especially with the labor intensive installation.

TSB 23-2350 and 24-2046 both call out for JR3Z-7H351-B CDF cylinder. If you got the old style then the dealer didn’t follow what 23-2350 told them to do. Do you have a copy of your repair order and if so what part number did they install?

That is my point - the old part number should not be available to order, now I am sure you can find them via online parts suppliers but Ford supplied parts should not allow the older part to be ordered/ sold or installed.

Or they only did the reflash and valve body update and didn’t touch the CDF

My bad, they DID the new CDM, I edited my post.
It broke down again 3 weeks later with a stuck 'Control Valve D', was towed in for 2 days and still isn't '100% right anymore.

I think ? ill print this out and just start going dealer to dealer and bug the crap out of them till I find one that will do it ...

Part of this is Rangers are starting to build milage on them and the problem is starting to rear it's ugly head. This will get much worse as the trucks rack up mileage. For some of us it will be to late.

My truck is a January 2019 build, so one of the first trucks. I preorder it, when the banks opened. At 65k, I started to notice issues, and did the fluid, filter and pan change. This got me to 90k (+ 6k flat towing) . The truck is pretty much undrivable at this point, and spending $6-7k at the dealership is not a option. So I bought a "new" used transmission with 5k miles on it, that will hopefully get me another 90k. We'll see what happens from here.

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.

Should be covered under 5 year/ 60000 mile drivetrain warranty. Have them try to explain why not.

If they do a software update or reflash, does that affect your tune?

Steve, they told me that they spoke with Ford, and since I didn't have any DTC codes to follow the shifting condition I was experiencing, Ford told them that the software reflash would not be covered. They did say if it had to go back for the next step of the TSB, that they would contact Ford to see about getting refunded.

I read the TSB as codes or these conditions?

I had the software reflash done and it was covered with no questions asked . I would contact Ford customer service directly and explain your situation. I think your dealer is trying to pull a fast one. And maybe think about using a different dealer going forward.
