6L80-E Transmission - Transmission Repair
Вставка
- Опубліковано 13 жов 2024
- On this video we talk about the common issued with this particular unit. The most common is losing all forward gears or stops moving forward.
There are different reasons why this can happen, I cover a different issue on another video on a check ball that wears and blocks a hole on the separator plate, go to my channel and look for that.
Thank you for the video. I've been trying to one up my dad. He's been building transmissions for 31 years. I built my first 6l80 today. Everything went great. Your video was a big help. Now I can finally build a transmission my dad hasn't done yet.
Thanks for bringing us along. As unlikely as it is that I will ever tear apart this or any other transmission, I still enjoy seeing the internals and learning about how they work and how they break. Thanks for making the videos you make.
I watched the whole thing and know nothing about transmissions.Very interesting to watch!
I always loved building transmissions it got my mind off everything but the actual transmission, I would get so involved and interested in what went wrong and how it could be improved. Great video very informational hope you continue making them!!
Thanks for sharing your video, I enjoying watching 6l80e walk through tear down, explaining why it fail and thanks again, John from Peoria Az
You are the man, I am a very experienced mechanic that doesn't know anything about transmissions. I had a 4l60e I was working on and one of your other videos guided me through fixing it, it worked perfectly afterwards! Now I had a 6l80e that is acting up on the 456 shift and this video is helping a ton!!!!
Super helpful video!!! You did an excellent job explaining everything in both layman's terms and technical terms. This is coming from a mechanic with 5+ years of experience, but not much hands on experience with gear boxes. I look forward to checking out your other videos. Keep up the great work and stop stressing so much about the camera angles. You did a great job. Thank you!
Great info! You are the first I watch if I need tips! Be great to see rebuild video on 6l80/90e if you get the time. Thanks for all the time you take to explain everything like always!
Great video, thanks for posting it, it really helped me out, I am not a transmission tech but with this i was able to rebuild my 6L90 by myself and it shifts perfect now, not everyone can afford paying a shop to do this so i had do it myself, thank you..
Always a pleasure to see the master at work!
I've done many of the th350 and 400, even c4 and c6, which I think are very easy rebuilds, You make this look even more simple. Thanks for the video.
Wow Mr. So-called Beer-belly this was A " Helluva Presentation " with SoMany step-by-step details most videos will Not Show..THanx Dude keep-em rollin' ! 💥
Nice Video and Very Informative.. Will this be the same for 2018 Silverado 5.3L? Getting the TCM P0700 DTC and shifting hard.. Is it hard to change that out?
Thanks great video my friend i would dearly love to see video of the unit being re assembled including piston replacements, thank you for sharing your time and expertise with us and cheers from down under Col
I really do enjoy your videos Hiram. As a professional tech myself I find your videos thorough and informative. You've saved me time on the job with diag already. :) keep 'em coming.
Awesome detailing and all! Thank you very much and blessings to you and all.
Great Video , I always appreciate a master of his trade that takes the time to shoot a video like this. Very interesting . Thank You !
First one of your videos I have watched. I must say, "awesome job"! I own a full service shop but we do a lot of transmission rebuilds in house. I do all the trans rebuilds myself, which is a pain with running the shop also. Anyhow, you gave some excellent information. I had not ran into the issue with the boost valve passage machining mismatch between the pump halves. That is something that could really bite you in the butt and take a lot of time trying to find the issue. I have had two GM pumps that had a very rough "face" on the stator side. Almost like the milling bit broke or was damaged and made a grooved finish instead of being smooth as glass. I truly appreciate you taking the time to make the video. I have done this for a lot of years and am constantly looking for odd problems or better put "solutions". I subscribed and will take a look at your other videos. Again, thank you.
Thank you for the great video. I rebuilt and upgraded my own 6L80 thanks to your video!
Dude, thanks for taking the time to make and post the video! Holy crap, these are complex!
Que marca es la pinza con la quita ese seguro interno tan grande? Gracias exelente video!!!
Another great video Hiram. I always look forward to your tear downs and common problem videos. Keep up the good work!
When you get another pump assembly does it come complete or do you have to use your old valves? If so, Do you use the Sonnax Zip kit on this unit that comes with the new pressure regulator valve?
Thanks.
Thank you very much sir, i feel 10000 times better rebuilding my 2014 now. You sir are my hero this week ... lol. Liked seriously
Cory McDonald how works the transmission after rebuild
@@MrJunior6939 well I have about 30k on it, I noticed when I put it in that 3rd gear was 0.020 away from the upper limit and now on hard pulls and light throttle it slips ever so slightly. It needed new steels on that gear.....so.... I have go back in it to replace that better other than that it wasnt bad at all.
Great video Hiram. I just ordered a reman 6L80 for my Silverado 1500. Watched this video and now I want to tear into the bad one but, dang it, that core charge though!
I also saw a video on removing the thermostat that GM installed on the 6L80's that go in the 1500's, specifically the 2014. Is that something that would be beneficial? Apparently, the 2500's don't have the thermostat. Mine runs anywhere from 194° to 205°.
Superior makes a bypass for it. It allows for full time cooler flow. Ask your local transmission parts place for it. It installs in the original cooler bypass. I have a way to bypass it, I'll make a video later when possible.
Now that’s a full rebuild good work sir
Excellent videos! I have to rebuild mine and I'm probably going to watch some more of your videos before I do and watch yours a few times while I'm doing it. I also live in Houston. Do you know where I could find a rebuild kit for the 6L80 out of my 2011 Suburban here in the Houston area or on the Northside anywhere? Thanks
Hey sir, I was wondering if you had any assembly videos with you measuring all the clearances on the clutches and seal replacement for the 6L80's. Awesome video led me to find more things while I have my trans out. Thanks
I've probably driven by you on 10. Lol I drive back and forth from Houston to the LA MS state line every 4 days for work. Awesome video. My 2014 Silverado has been in the shop twice for transmission issues. Lost a torque converter once. The damn thing has hunted gears since I can remember. I believe thats mainly due to it being an "off-road" version from Rocky Ridge. 35's, 6" lift and the same 3.42 dif gears. The first and the last one I'll ever buy. Anyways, planning a trans rebuild soon and this video was well worth watching. I appreciate the insight. Awesome vid.

My 2014 silverado is gonna hit 100k miles tomorrow and zero issues
Probably just shouldn’t mod your truck that much tbh especially when it’s a 1st year redesign and the tunes and stuff haven’t been tested enough..
Thanks for the video my transmission just went out on my 2007 cadillac escalade, when i turn on the vehicle for first minute I have forwards and reverse but after that minute or so I lose them again any idea , how much is a rebuilt thanks again
Thanks H. , Start prying , Start praying . definitely had to lay hands on it
Thanks for the video awesome! Truck is in shop with what started out as 5-6 slip, changed fluid and filter, found non ferrous metal in pan, after fluid and filter change, truck would not move in first when warm and delayed 321 downshift. Anything I should keep an eye on while in shop? Thanks again for the awesome video.
Were you able to bring it back to life? Great video by the way. I quite enjoy watching you work your magic. Thanks for sharing.
***** I think that's really cool. To be able to keep all those different transmissions in you head. I'd have to bag and label every bit and piece that came off one of them and take a million photos so I could have half a chance of putting is back together. Great videos, keep 'em coming.
Hi Hiram, great videos, no messing, straight to it.
What size are the snap ring pliers you have used in this strip? I'm about to rebuild my 5l40e, really wish you had a video on here of rebuilding one, especially with the piston install.
Keep up the great work.
Cheers,
There are two distinct output shaft assemblies: one is a single unit, while the other is not. I would like to inquire if there is a difference in the speed sensors utilized for each assembly. Additionally, I am interested in understanding the potential consequences of using the incorrect sensors for the respective output shafts.
Like your videos. I heard you say (here in houston ) in this video. I'm having problems with my 6l90 trans. Im in Houston. Do you have a shop or somewhere I could take my transmission so you can take a look/work on it ?
Hello Hiram,
Your videos are the best - Thanks for making them and sharing.
My question is - Can you tell me the difference between the 6L80E and the 6R80E.
My 2016 3.7L Mustang has a 6R80E in it.
Again my thanks for these educational videos.
Vince.
Hiram,Nice work and enjoy your videos, one question on the 6L80E. What other than keeping the fluid changed can be done as preventive maintenance? For a light towing vehicleonce again thanks for sharing the Knowledge1
Add a better trans cooler.
Great Job Hiram. These Torque converters Always come in smoked and the clutch Plates have no Lining left, usually Goes Metal too Metal. Thats Probably what you found in the Pan. you think the PR Valve Can cause this problem for the torque converter? or can it be the boost valve giving lack of lube due to Low Line pressure? your feed back would be great. Had customer have this unit come back 2 3 months after over haul tranny smoked and when i cut the torque open the lining is completely gone.
GM has upgrade the piston damper on these units with beefer springs and better casting I'm pretty sure it's not the piston cracking. It's definitely in the tranny.. how is the lock up valve when you go threw the valve body? Yah look in to it when you got time could be very helpful for the me and my guys.
And anyone else having this issue
How do you know this guy is a traveling man?
Good evening. I hear that you are located in Houston, TX.
Where is your shop located?
@34:22 OFFICIALLY, the story on the 6L80/6R80 is that it was developed in a joint venture between GM and Ford. Unofficially though, you're probably right given the fact that almost every car manufacturer on the planet has used an Aisin unit in something of theirs at some point in time.
FWIW i didn't use pliers, or use a screwdriver, i used some mechanics wire, threaded it through both holes, and twisted it over the end of a pair of line pliers to compress the ring. wish i could post a pic but it worked great
You really know your stuff! Very knowledgeable. Thanks for sharing.
Do you have a tool/part number for those ratcheting snap-ring pliers?BTW,what are bench buddies?Thanks for sharing!
Love your stuff bro.i work for LKQ in the transmission plant.your stuff helps out thanks brother.
Really? I put an LKQ reman 6l80 in cust truck. Its starting to have problems. Lol Its no prob we got the gold warr. Just thought this post was funny.
THANK YOU! This was just the info I needed!
I'm sure you have been asked this before. Where is your shop. Thanks and Thanks for sharing these videos.
I love these videos. Where is Hiram's shop please ?
How do we eliminate or prevent the fine metal particles from destroying the transmission? Regular transmission fluid maintenance?
Great video for not being ready.
Where is the shop located? I'm in Houston as well
Hello Hiram I have a 06silveradoCrewcab4x4 no 2nd or 3rd. Do I need a full rebuild. What could go wrong and how much should I expect to spend, thanks really enjoy your channel
Very informative and straight forward video. Great job & Thank you .
your awesome !!!! when I grow up I want to be like you.
Great video very useful*****
I want your help on my 2009 caprice has 6L80-E and it is sometimes harsh shifting on 1-2-3 first shifts and sometimes it shifts normally when the car is cold
there is no codes . one time happened that when it shift from 3rd to 4th gear it stuck for 2 second and then it shifts harsh ,in the morning the problem gone!!
also another problem when slow down then accelerate at 40-70KPH it slip(go to N then engage after 2 second)
what you think is the problem?
thanks
3 years and no reply. Rip
Great Video Mr. Gutierrez, I was wondering how can I get you to do a rebuild for me on a 6l80e. I'm located in Houston Texas as well.
harm good job on the teardown and the valve body...
you have it going sir bud amazing
hey hiram that pump and turbine case looks score did replace it as well or i was the video that make it look like it
It was interesting watching you realize you were incorrect in your previous video. The "incorrect" new bellhousing you had before is just like the one you have in your hand. The 6L90 has a different grove in the bellhousing but they both work.
Are 4L80 & 6L80 both about the same, which will stand up to most HP? Thanks, Bo
Where are you located in houston? I have a 2009 6l80 that needs to be rebuilt as soon as possible !
What i would like to know is what aftermarket real good parts can you put in the stock GM 6L80 e to make it last longer and make it easier to service as they do not have a noramly re filling opening?
I have 3 6L's ready for rebuilds. If i get atleast one goin im buyin you and anyone else i watch a fine import. God bless and stay safe
How do I get in touch with you. I need a transmission rebuilt for a 2009 suburban 4x4
Where is your shop located i live here in Houston as well katy area???
Could you recommend a good shop in the Houston area My 6L80E needs and overhaul. Love you channel!! Thanks
this is late but Hiram is located in Deere park near Houston.
Edit: spelling
So exactly what caused the destruction? Was it from the worn valve? Then everything else went?
Which rebuild kit brand do you recommend for this transmission? Gonna rebuild my trans on my GMC long time technician just not familiar with brands but definitely do able
Can I ask if the 6L80 and 6L90 need a TCM reprogramming after only changing the stuck Check Balls and spacer plate ?
Hola Hiram! ¿Se puede lavar el Cuerpo de Valvulas y la Bomba con desengrasantes a base de agua o biodegradables?
You do a really good job on these…thank you. Plus you audio is good!
He is calling a snap ring when is a circlip relay if its got little holes on each end then its a circlip? which you can buy circlip pliers to help you remove or put them in?
I was taking some AT. units in School we worked in a 4L60,BMX-A,4F27E Are there any videos on Ford AT's.
Is there anything you can do to help prevent failure,like replacing fluid regularly?
Cl80 2015 gmc Seirra 4x4 do I have to remove the valve body before I remove the bell housing
Oh wow friction plates look identical to dirtbike / motorcycle clutch packs.
How do I know if I need 24248569 (17.948mm), 24248570 (17.961mm), or 24248571 (17.974mm) when ordering fluid pump rotor kits for a 6l80? I haven't gotten the ATSG manual yet, I was trying to order some of the parts I know I'll need/want along with the manual before I start the teardown. Is there a measuring technique for this outlined in the service manual?
Rebuilt a 2012 6L80 now I don’t have 6th gear Shifts hard and real quick, new convertor and pump.can U telll me what to do next
Now I know how much labor cost it takes, thank you
I have 2015 suburban rwd lt. In summer hot days it used to hard shift and on constant speed even on little uphill it was jerky as in wrong gear. All winter it was good. In summer changed fluids and filters twice didnt help tried adding additives make it shaky at idle in gear. So what causes over heating and hard shifing in summer. Do i need a new torque converter or rebuild? Winters ending so concerned to get it fixed. Thanks for any help i can get
Do you know if internally this is essentially the same as the 6l50? Online its been hard finding almost any information on the 6l50 despite being used for so long in so many cars
How about change the fluid once in a while.LOL thanks for your dedication Hiram
When you pulled that valve body I had to jump back and make sure I didn't miss anything. Is that normal now to have the whole valve body as a unit and not be half in the case with separator plates and gaskets?? By far the first one I've ever seen come apart that way. I've never rebuilt a 6spd before only 3-4spds. Then you spun it around and the from pump comes out with the bell housing!!! What kind of evil is going on here! Crazy! Now I gotta watch the whole damn video to see what else.
Awesome comment.
Hiram, hope you are well. my name is James I left a message for you when I looked up your shop online and noticed we were in the same city. I was hoping to setup an appointment with you and see if i have burned my 4L60E trans. in an 04 C1500 it still works and has only slipped on me once but in the summer it shifts rather hard. Also it consistently knocks after it finishes upshifting vibrates on downshifts no matter the temp/season
Please let me know if we can set something up
Where did you find the Orange Ed China gloves? They look durable
Hi, can you advise?
when I get listed on "D" it jumps up
1 gear. when I put "M" so the car starts.
Other speeds also go to "D", but with little gas slipped.
Gums in the gearbox are ok, solenoids (their resistance is ok)
the car has reached 60,000mil.
I gave a new oil. but with the air test, I do not move the basket for 1-2-3-4
only a few.
can you please give advice?
Hi! I like to watch your videos. Can you tell me please, what kind of camera you use? Make model
Where in Houston are you located? I’m needing my 6l80 rebuilt
Do you know why my 4T45e transmission leaks a lot after rebuild. They've replaced side pan, bottom pan and,axle seals almost 20 times now. Could it excess pressure ? Thank you
is there a specific kit you recommened to rebuild these 6l80s?? from the piston to the all the frictions??
anybody know? Pulled my transmission today now need to rebuild it. First time ever rebuilding a tranny
Circle D has kits
I have a question. low / reverse part (non-detachable) revolves only in one direction? and goes to light? can you give someone a video and spin it? PLEASE
With that much contamination combined with the complexity of the valve body, wouldn’t be best to just replace the whole valve body? Great video BTW 🤘🏻
Mr.Guiterrez would u make a video rebuild for a B4RA transmission please.Or if u have one already can u upload it thanks.
I have a 2011 z71 4x4 with the 6l80e it has a bad tcm bad torque converter I want to replace it with a 6l80e from a 14/15 silverado. My question is if it's compatible for my application
Hi, it seems that you don't repair any Toyota transmissions because I don't see any videos on Them.
What all has to be done to remove just the bell housing? I noticed you dropped the valve body and seals prior? Is all that needed to be removed to just do the bell housing?
you dont have to remove the pan to pull the Bell Housing just remove the 9 15mm bolts
RT
great job, I could do one myself now,just would have to use a camera to film the steps etc???
Question I have a built 6L80. I lost 456 gears in it. 123 and reverse work still. Any idea what could cause this?
Aisin has a factory in Indiana, half the company is owned by Toyota, and they also make furniture, ac’s, toilet paper and stuff like that
hello you advise?
on D, my car won't move. the M starts off but the 1st, 2st, 3st at full throttle clutch slips.
I changed the seal to 1,2,3,4. sealed to thcm, oil, filter. there are no wear parts in thcm. the pump seal is replaced. everything looks intact. the car has driven 60000mil.
the stator rings are replaced.
