You /I think so considering metal flakes were found. Do you have the service paperwork to check?

Cannot trust asking and getting an honest answer these days.
I will check the paperwork again, but I think fluid change was mentioned. Been a couple weeks since the work was done and I last took a look. I had thought that to access the valvebody, you have to remove/unbolt the lower trans tray and fluid would pour out?

The transmission filter should have caught metal flakes am I wrong?
Filter would catch the pump damage flakes before it got into the valvebody? Pardon my ignorance, I've probably watched hours of 10r80 disassembly videos and still haven't much of a clue how it all works. :crazy:

I dont know if you are under warranty or tuned or whatever. But I was having really bad downshifts occurring too. They took my 10R80 apart multiple times and nothing they did ever helped.

I recently installed the FP Tune (to keep my warranty) and the tune has completely transformed the downshifts on this car. They are ALMOST completely smooth now. No more having it feel like the rears are locking up (for a split second) and no more feeling like I am getting kicked in the back coming to a stop. Its been a big improvement.

I am convinced that Ford just poorly programed the stock 10R80 tune. Just something to consider.

Pulling the pan & valve body does not drain all the TF, about 1 third or so at most.

I have watched transmission videos as well. I did replace my transmission fluid and filter recently because I was curious to see if there was fluid discoloration and/or metal in the filter. I have only 43,000 miles on my car. I had my local Ford dealer do a transmission fluid/filter change at 25,000 miles and here's the really curious thing I learned. When I opened the transmission filler "cap" I got a stream of fluid coming out! This is not normal. The transmission was cold btw. Check the transmission fluid level if you have work done on your car.

And if a dealer tells you they can do a full transmission flush, they can't.

So I want to make a comment in here since I'm not sure if anyone has taken a look at the common 10r80 transmission thread that was linked on page 1. It had become what seemed like a pretty common issue that these transmission had not been completely full from factory before being shipped out.

I had some issue with my Mach 1 somewhere in the 4000 mile range one day where I started getting just the worst upshift from I believe 3-4 and then on almost every downshift from 7-6 I want to say at a coast I could hear a clunk and feel it in the accelerator pedal. Vehicle did not jerk or jolt on the clunk, only on the harsh shift. Problem was present in EVERY drive mode except for Drag.

My trans fluid was a quart low and after it was topped off everything was butter smooth for a bit and then sport seemed a little harsh again the following day when I drove it which I will just chalk up to it being how sport mode drives. Since I've gone through all this and experienced it I only ever drive the car in Drag mode now, or if I'm going to be doing some true spirited driving it will be in Track. Drag mode is just always so smooth unless you're on it and making the car shift at redline, in which case, it does what I like to just say is that it feels like a rubber band or rocket between shifts lunging the car forward which feels fantastic.

TLDR I always drive the car in drag mode unless I'm going to be doing spirited driving and then it goes to track. Fluid was 1 qt low from factory and was not checked till close to 5000 miles and haven't had any major issues in the last 7000 miles since fluid was topped off.

I'll tell you, this whole transmission thing is both fascinating and frustrating. So many different experiences. My transmission continues to run what I consider to be flawlessly, after a simple fluid top-off and accelerated break-in. The only problem I experience is the bogging in Normal mode at around 40-45MPH where it sticks in 10th gear.

But it's so smooth in Sport+ mode that this is the mode I drive in except when my wife is in the car. Then I shift into Sport mode to avoid the extra noise, which bugs her after awhile.

If they would offer a Tune for the 2022+ I would GLADLY make the purchase.

I am wondering if the 2021 Tune would actually work on a 2022. The MAF Sensor shares the same part number.

I checked the paperwork and this is what I see:

I’m taking the car in tomorrow for a tech ride along but I still haven’t test driven another 10r80 - been super busy lately. I’ll try to get a test drive in either later today or early tomorrow before the tech drive.

I decided to go to a closer dealer than the one I went to before that recently replaced my valve body(10 min drive vs 50 min drive). I test drove a new California special 10 speed mustang and it was noticeably smoother shifting, and also pulling harder while in gear! So I definitely feel that my 10r80 still needs some work. (The CS mustang doors also felt and sounded much more solid when closing!)

Immediately afterwards, I went for a tech ride along and we had a long conversation about the 10r80 and it's/my issues. He also confirmed that mine was shifting a little rough on certain gears, as well as some slight clutch slipping. He told me that since I had been experiencing these rough shifts for so long with the damaged valvebody, that it is likely that other internal components/clutches are also overly worn. We started the paperwork and he is going to check with Ford hotline to see what next steps should be.

During our conversation, he mentioned that the 10r80 has been a common warranty repair item, and that there are lots of issues with them. He said that the biggest culprits are the extremely tight valvebody tolerances, along with the ULV fluid inability to lubricate/protect, and that there is a small main forward gears "E or F?" clutch pack that is often engaged and wears prematurely/unevenly.

He told me that there are a few possible outcomes for me here:

1. He does his tech drive with computer logging and finds faults
a. Ford possibly says to replace valvebody again(WHY?!)
b. Ford authorizes teardown for evaluation/inspection
- if damage found, clutch packs, steels and any other worn components replaced
- if damage found, and parts are on long backorder, then possible entire trans replacement authorized
- if no damage found, then he will likely replace the steels anyways and the case is closed. I would ask them to install Mcleod clutch and steels kit if this was the case.

2. He does his tech drive with computer logging and finds no faults
a. We will revisit and probably ask ford to authorize or subsidize trans tear down/inspection
- If he finds damage, which he strongly believes he will, then we do step b above.

I really hope they will authorize the teardown and rebuild. I'm lowkey even willing to ask for the teardown and pay the labor costs if they don't find anything, because I am that confident they will find damage.

Also thinking of having ford replace with this kit after speaking with Terry over at beefcake:

UPDATE:
1. Tech did his data logging and found no errors, but that there was clutch slipping(Shift Flares).
2. Tech requested next steps from Ford hotline and received approval for teardown/inspection.
3. Tech did teardown and found damage(Scoring, valve sticking and metal flakes in valve body, excessive wear on #3 sungear and planetary carrier, scoring on Torque converter, tons of heat damage on F clutch + B clutch pack)
4. Ford will be replacing entire transmission under warranty! :rockon:

I can't state how much of a relief this has been, and now I'm just itching to get the car back with a properly functioning transmission!

Good to hear that the trans is being replaced under warranty. Not that anyone wants to have a bad trans, BUT they are making right on the issue. The other thing is, it's good you have a GREAT Tech too - that helps 1000%. If I were you, I'd always request him if needing to return for ANY work. It's good to have an inside guy who does right.

Someone at flatrock must be getting a bonus for savings of sending each unit out the door a quart or two low.
Wonder how many v8's are going out the door with less than 10qts in the pan.

I agree 100%! I just brought a couple dozen donuts for my tech and SA. SA wasn’t in yet but the tech was. He really appreciated it, and I spent a few minutes talking to him in the bay. He showed me my old trans, and explained that it was one of the worst condition trans he’s seen. He showed me multiple areas of excessive wear, discoloration and heat scoring.

I thanked him for all his help, and let him know that I not only appreciated how friendly and communicative he has been, but also how knowledgeable! His manager wasn’t in, but I’ll be putting in a good word for him in the coming days.

I believe I have warranty on the trans for another couple years now, so not sure how I will proceed with the car. Might not touch it and just street it for a while, might do a trans thermostatic bypass replacement, might just sell it honestly. I have some thinking to do.

Here is a picture of the steels:

Hello All,
I have only 350 miles with my mustang gt and i have the same problem.
I went back to the dealer and the engineer told me that "its normal and the adaptive transmission " will eventually "adapt". So let's wait a little. Of course, i don't want to go more than 300rpm but im trying the sport mode from time to time.
Anyway, it is disturbing when it shifts from 3rd to 4th.
