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

Thank you Gary.

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 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?

[@GaryFerraro]

If on 3-4 shift, i would say rear stator bushing is worn out or maybe valvebody issue, Rear stator bushing is a fairly common problem for a 3-4 flared shift

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...

[@GaryFerraro]

Thanks for the tip

Hello, Gary, I repaired an automatic transmission optra 4hp16, 2008, when moving to 2 speed it hits hard, it does no have fault codes, therest of the changes go well, I changed the valve body, par converter, switch TR, if I try the cat no no it hits, if I do it slowly, high speed I don't know, greeting from colombia

Saludos a la distancia Gary consulta tengo una 6R80 ford raptor 2012 me produce un ruido al cambiar 3era a 4ta como traquido pero al desarmar no se ve ningún daño de piezas rotas

[@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

[@GaryFerraro]

I think they want to see what happen and maybe fix to sell as reman

[@josephfigueira813]

Maybe a recall and don't want you to know that.

[@Wdthyfdo]

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

[@adrapa6022]

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

[@shaunhuckabee5904]

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!!!

[@sergeinosov772]

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?

[@GaryFerraro]

Yes, could be a worn E clutch or worn out rear stator bushing

[@paulhastings7480]

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

[@GaryFerraro]

If it's a 6R80, no programming, may have solenoid strategy to program but even if you do not put that in should work fine

[@JuanRamirez-pp1nf]

What the cost of this to get fixed ?

[@raymondjohn3396]

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.

[@GaryFerraro]

so basically you broke a pan bolt?

[@raymondjohn3396]

@@GaryFerraro yes, and the as I saw a thunderstorm coming towards me, I rush to put pan back together, but I accidentally stripped the bolt and the head of the bolt broke. Next day later, I took the tranny pan off and I use a small drill bit to drill the strip bolt and it drill through but I'm risking the threads and might do it wrong. I use a extraction tool but it broke.

[@GaryFerraro]

@@raymondjohn3396 Well You may have to drill it out and install a heli coil, you may have to buy the kit, you will have to get the thread size it may be 6x1

[@raymondjohn3396]

@@GaryFerraro i already bought the heli coil kit, but the tranny pan bolt is 8mm socket small. So if the DTC code says p0741 then its the part right torque converter. I didn't have any other issues like reverse, drive, neutral, when driving. I am the second owner of the f150 because someone else had this truck before we purchased it in 2016. I talked to the ford motor, they told me to replace the seals while you're replacing the code p0741.

[@GaryFerraro]

@@raymondjohn3396 These converters do have issues, Valvebodies do to. Converters are more common to fail. Actually there is a test that can be done but you need a pressure gauge. Converters do fail often

[@CalicoRiot]

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 💀 ☠️ 💀

Which drum? or what time in the video?

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?

[@GaryFerraro]

I believe ZF do can crack, if they would work in a 6R80, not sure, there are different part numbers

[@jonarmedpiandsecurityoffic9051]

There are no aftermarket hardened products available for the 6R80, the only people I know of who are big on the 6R80 is power by the hour, and there is no aftermarket billet or hardened overdrive clutches sold by them, nor are they aware of it anywhere else

[@GaryFerraro]

[@reallystockmustang7178]

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

[@GaryFerraro]

Almost sounds like your talking about a clogged filter noise

[@reallystockmustang7178]

@Gary Ferraro its coming out this weekend. It lost 456 but still drive 123 i got it home and parked it ill try to post after i get it out and torn down i did a 7r and a 6l rebuild before. Crossed fingers.

[@reallystockmustang7178]

It was a broken clutch hub. But one question Sir if the shaft snapped and the shift pressure was up due to a tune could it still drive but with slipage? E drum is good tested it like video no bubbles.

[@GaryFerraro]

@@reallystockmustang7178 Not if the shaft snapped E clutch will not engage

[@Kam0917]

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

[@GaryFerraro]

There was about 110K, Not sure about model years prone to this, this is a 2012 F-150, and my first cracked drum with this trans

[@paulhastings7480]

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?

sounds to me like the E clutch is no good, you checked the fluid level?

Is this by chance a ford Transit?

[@rleojeda]

It is not. It’s gen 2 off of a Mustang.

[@rleojeda]

We replaced the bushing stator and all the steels and friction. But didn’t fix it. It has a billet shaft and it isn’t broken. Are those the only 3 things that can go wrong when you lose 4,5,6? Bushing, cracked drum, broken I Shaft?
