6R80, No 4TH,5TH or 6TH

I had overhauled this Transmission about 6 months ago and came back with no higher gears, the problem being a cracked E clutch drum, i show this by air checking the drum and showing the leak. A new Ford drum was installed as well as new clutches and steels. Got him back on the road again. Thanks for watching everyone and Happy Thanksgiving to all.

Thank you for posting this helpfull video. I would need your advice on a situation that I am currently facing, and couldn't get a scientifc answer to my case to all visits I paid to local mechanics.

I drive a 2015 Mustang GT, that was like a charm ! The car has only 120, 000 KM with 6r80 automatic transmission. I went to a track day for the first time, and after that the transmission started to behave wiered when changing from 3rd to 4th gear <lagging, jerking and even car goes into limp mode> after the track. there are ZERO erros, scanned by Forscan and LUANCH on the whole car.

I then re-installed the stock air filter and loaded the stock tune (from JLT air filter and SCT pre-loaded tune), expecting the car to go back to normal. I drove it for 40 KM so far, but the problem seems to be still existing though it happens "intermittently"

Yes, I smelled something in the track day but not sure where was it coming from. Could it be solenoid issue? is it the clutch? the tcm?

Nice video, please be careful not to blow air into you blood vessels when checking for leaks or other. 😮

Buy a magnaflux kit, that's what I had to do to lots of Honda drums years ago for that same sort of problem breaking by the weld. 2/4
drum...

Hellos gary, good morning, my problem in mumy 6r80, the reverse on some uphills does not work and the street is flat, what is the problem? Help me please

[calholli]

I wonder why they would want the core? Do you think they would weld that long crack and re-machine the part and sell it as a re-manufactured piece? I can't understand why they would want the core charge-- unless it's just for the scrap metal-- being a special steel or something. Or maybe they test it and see what went wrong and why/where it failed? ?? idk

So what's the main culprits for these internal transmission failure... lack of service ? To much hp ? Or just under engineered ?

Hi, i have a F150 2015 with 68000kms (42500miles) :
Upshift : 3rd slip to 4
Downshift, 3rd—>1st when i stop the truck. If i don’t stop, I need to push the accelerator all the way for the 3rd down to 2nd.
But in Taul Haul or sport mod’s downshift no problem !!
What do you think, please

How much would you charge to rebuild a 5R55 out of a 2004 Lincoln LS? The trans has had the servo bore repair done by the previous owner. Thanks!!!

Hello! Thanks for your video! A have Explorer 2009 4.6 with 6R60 (or maybe 6R80 gen 1). Everytime I drive on highway I feel rough 4-5-6 shifts. 3 times of 10 they are smooth, other time-rough. Can it be because of problem with e-clutch drum?

[paulhastings]

I purchased a news transmission for my 2016 mustang gt and need to know if they need to be programmed, or anything or are they plug and play like a 4l60e chevy truck transmission

2009 ford f150 4.6 engine with 6r80 transmission, had 193, 500 miles. Wrench light came on december 2023 and use my obd2 scanner DTC p0741 for torque converter. And I reset the code, few weeks later, as I put "lubicant shutter fixx into transmission, then as i heading on Febrary 2024 as i was going uphill i felt a stud sound, and wrench light came on, recheck the obd2 scanner there the same code p0741. And as i drain out the transmission fliud, i stripped the bolt that holds the transmission pan, and as the bolt head broke during the stripped, I tried using the extractor tool but it also broke. We tried to put transmission back on after we replaced the seal, torque converter, working on unstable ground makes it tough to reinstall the tranny back. Any clue on what to do here.

How on earth did you get that retaining ring off the balance piston? I bent some external snap ring pliers trying to remove it. I've been trying to find something to do the job, but everything that looks strong enough is also too big for the gap in the ring 💀 ☠️ 💀

Hi Gary, are these Ford boxes license built by Ford? Would a ZF 6HP26 drum fit in this box instead? I am just wondering if the ZF boxes suffer this type of cracking as a common issue? If not, could you fix the issue by putting in a ZF part?

[reallystockmustang]

If this happens could you get a noise when shift like a high pressure leak noise shooooink sorry its hard to explain.

[Kam]

Are there certain model years that are more prone to that failure? Do you know how many miles are on that transmission? Thanks Gary.

[paulhastings]

Mine doesn't shift into 3-4-5-6 has a DTC for friction plate A and that's it, 2016 mustang gt. What do you think it might be?

[erickeeley]
