Transmission Issue 10r80 (no more re-flashing?!)

[Papa Tiger]

On the Ford 10R80 transmission models, the solenoid body/strategy identification is as follows: The 13-digit solenoid-body strategy number consists of only numbers (1). Letters are not used. Compare the solenoid-body identification and strategy to the solenoid-body identification tag located on the left side of the transmission case. If the solenoid-body identification and strategy displayed on the scan tool match the solenoid-body identification tag or replacement tag, then the solenoid-body identification and strategy are correct for this transmission and a solenoid-body strategy data download is not required. If the solenoid-body identification tag or replacement tag is missing or damaged so it is not readable or does not match the identification or strategy displayed on the scan tool, remove the transmission fluid pan and filter and locate the 13-digit solenoid-body strategy etched on the main control casting (Figure 4).

The 13-digit solenoid-body strategy number displayed on the scan tool must match the solenoid-body strategy number etched on the main control. If the numbers do not match, damage to the transmission or driveability concerns can occur. If the new main control was not supplied with a replacement solenoid-strategy identification tag, DO NOT INSTALL the main control as all required programming information is missing. Compare the solenoid-body strategy identification etched on the main control to the solenoid-strategy identification tag on the transmission case. If the solenoid-body strategy identification etched on the main control does not match the solenoid-strategy identification tag, then a solenoid-body strategy data download is required. If the solenoid-body strategy etched on the main control does match the solenoid-strategy identification tag on the transmission case but does not match the 12 digit solenoid-body identification and strategy displayed on the scan tool, then a solenoid-body strategy data download is also required.

Let’s take a quick look at the hydraulic functions. Solenoids 1-6 are normally low linear solenoids for shifts and regulated line-pressure clutch control (Figure 5). When these solenoids are off; they provide pressure to stroke the clutch control valve allowing controlled line pressure into the apply clutch circuit. When turned on, no pressure to the control valve (stationary) line pressure will be blocked from entering the clutch apply circuit. The solenoid accumulator keeps the solenoid-signal pressure smooth. Both the power and ground circuits are controlled by the TCM. Note: Although these solenoids work the same way, each has a different part number for different flow rates and should be installed at their original locations.

Basically if a solenoid is switched it will mess the Trany shifts. If the problem occurs shortly after a Trans. service guess what? Pan pulled filter changed maybe a solenoid switch? I would do a search for more of that info.

Snowball recently got her Oil Changed, $100. Got home, it had a bad PCV valve and dirty Air Filter.
It had started throwing a Code for wrong manifold psi on the way home. U no that place is banned here forever.

My transmission is torn apart and waiting for all the new pieces to arrive at the dealership with only 42,000 miles on it. It has done nothing other than commute to and from work but couldn't even survive that...

How long has it been in the shop awaiting parts?

I dropped it off August 20th and they just got around to diagnosing and then tearing it down on September 7th.

Sheesh...that's ridiculous. I hope they fix it soon!

My dealer by my house (Berkeley Ford) the SM told me they're still working on transmissions from March time frame. He stated their transmission tech has and I quote "babysitting issues" and comes in between 11-2pm. I opted to drive an hour to Santee Ford. They've been great so far and said to bring the truck in for the pressure test and if it fails they'll order the parts and it's appx a 20 man hour job and I should have my truck back in a few days up to a week. They're a very small dealership and were super nice and detailed with explaining. Another shop in the Charleston area hasn't had a transmission tech in 4 months the other shop said bring it in 2-3 weeks to diagnose it then work would start approximately a month later. The 1 hr drive to Santee was worth it.

Took the truck in today. They conducted TSB 24-2304. It passed the "pressure test". So the dealer did an adaptive transmission reflash for the time being. It smoothed out for "now".

The service writer and tech were excellent. They said if it doesn't fix it they'll pull the valve body and everything else but give it the average 1k miles to see if it fixed (I know it won't, had the same issue on my 2019 10r80 which failed at 37k). I'm waiting to bring it in as the rut is kicking off and I need my truck for the next few weeks. Will prob bring it in Jan 2025 once deer season is over.

Just keeping y'all updated. If you want this done at your dealer they need to order the 6-7k machine (what they said) then they have to order all the follow on adapters.

Just recently purchased a used 2020 XLT (56k miles) with the 10R80 the other day. It is currently at the dealership now because I wanted to address the shifting issues immediately before the 5/60k warranty runs out.

Can you demand a CDF drum replacement instead of going through the maintenance procedures of re-flashing, pressure testing and whatever it may be? I assume the recent TSB spells out exactly what steps to follow, but I'd rather them just replace the drum now instead of having to deal with delayed issues before the warranty is out.

Probably not, if they skip steps in the outlined process they probably don't get reimbursed for the work/parts by ford.

Maybe if you get a good dealer (on my 2019 they didnt attempt to replace valve body or diagnose it...they put a whole new transmisson in but I sold it shortly after). But most likely they will not. With the new TSB they'll start with the pressure test (if they even have the tools). Then once the read the setting and do the calculations they'll determine if it passes or not. They opted to do the re-flash. If my problems continue they'll pull the transmission apart. Is what it is I guess.

Attached is the actual TSB

No and if you even hint at it, at least at my dealer, they'll attempt to get rid of you by making your next appointment months out.

I had my CDF drum changed last October (23') on my 2021 F150. The dealer at first charged me to reset the adaptive tables. I had already done this step on my own and did not resolve the 1-3 hard shift and 3-4 hard shift. But, they wanted to do to rule out it was not an easy resolve. After 1k miles I brought it back complaining of the same hard shift issues. They changed out the CDF drum per the TSB and have not had any issues since. This was done around the 62k mile mark under warranty. I am now at 101k miles and have not had the 1-3 or 3-4 hard shift issues since the drum was changed out.

Hey Mike, Have you had any more issues with your transmission? Mine is at the dealer now for the cold rough shifts.

I've had my transmission oil & filter changed at about every 15k. My dealer wondered why. My rationale is to remove whatever manufacturing debris may be in there floating around. I'm aware that Ford upped their cleanliness standards for this transmission facility. Still, there will be some "stuff" that gets in. Think about things: manufacturing, packaging for shipment, un-packaging at the assembly plant, handling to the assembly line, and installation. The only issue was it was slightly under-filled at the assembly plant. This didn't show up until the first winter when temps got down to about 15ºF. Dealer fixed that. Keep in mind that this unit is a hydraulic machine. Clearances in the spool valves are really fine and any debris no matter how fine can screw up a shift. SO far, knock on wood, my transmission is trouble free. Please note that this is not a slam on Ford's manufacturing process. I believe they do as well as can be done. I've seen this with Machinery on Navy Submarines where I spent a career. The issue is simply that there are ways to operate machinery that will make it near trouble free and long lived. My goal is not get to the next trade-in, it is to make my truck last as long as possible. Like my family Suburban that went 30 years and helped get three sons thru college.

Thank you for your service.

CDF drum seal movement will cause rough 3/4 shifts. Hence the new part # for CDF drum mid 2022 and the TSB for transmissions manufactured before the change.
