Meat and potatoes only, showbiz belongs somewhere else, thanks bro.
You’ve made my Saturday night! So great to see you once again!
Wow, thank you!
@@AutomaticTransmission It's good to see a new vid. I keep going back and watching them again. Stay safe and hope things are going well.
What a great explanation of what is actually happening to the converters on these transmissions. As always Hiram does a great job. Keep them coming.
Hiram, so great to see you again man! Welcome back!
Hiram!!! The man. It’s great to see a new video from you. Best wishes to you and your family in these crazy times.
Much appreciated
I learned so much about transmissions just from watching your videos. I'm an Industrial Mechanic, and although I've worked on rather complex hydraulic equipment, they don't really compare to a compact transmission.
My sierra tranny is failing. I learned quite a bit today. Thank you.
It's good to see you're still alive & kicking.
Ohhhhhhhhhh mi amigo a la lejanía. Que alegría escucharte y verte de nuevo aquí en tu canal. Compartiendo tu conocimiento y experiencias. Gracias Hiram. Continúa. Saludos desde Venezuela.
Happy Easter, y'all...Hiram's back
Good to see new videos again! I rebuilt one of these 2 years ago on my own 2500 Suburban and spared no expense... it only lasted 36k miles before the convertor took the trans out again. I didnt have HP tuners and wish this video was around back then. But now I swapped a 4L80E and not going to have to deal with this fragile trans anymore.
Glad you're back. Nice work!
Hey, thanks!
Glad your back, your vids have saved our shop a lot of headaches.
Hiram, great to see you posting again. Wish your shop was closer to me, my CVT (RE0F10A) locked up while I was driving it and had to replace it with a junkyard unit.
It’s better to just replace the 6L80 converter with a 6L90 converter as it’s a much stronger converter than the weak 6L80 converter. I upgraded from the 6L80 converter in my suburban to a 6L90 converter and my transmission shifts as smooth as ice. I also upgraded to a larger trans cooler. I also deleted the AFM system completely.
How much did this run you? Thinking about this
@@jacksonevans9378 if you had it done at a shop they would charge you about 6 or 7 hours labour at about 100 bucks an hour plus the cost of a torque converter.
Converter prlly cost like 700 bucks .
Total would prlly be like 1500 bucks minimum at a shop
@@jacksonevans9378 which part the converter, cooler, AFM system delete or all of it combine?
@@joshuaraffensperger3592 converter
@@jacksonevans9378 $800-$900 if you do it yourself. $1200-$1500 if you have a shop do it.
Good to see you posting videos again, Hiram! Great video, I'll make the HP Tuner changes with my 2013 6L80 and hopefully avoid premature T/C failure. As always, excellent information and guidance.
Thanks, there's more to do than that on HPtuners to the 6L80E. I'll be posting a video on it soon.
@@AutomaticTransmission can we get a video on all changes i have a 2016 with almost 50k and i just got a hp tuner to fix my issues before it blows thanks awesome videos and details
@@AutomaticTransmissionwhere are you located?
He’s back! Whooot!
alive and kicking
Great to hear you had me worried. I found you looking up O1M rebuild videos. Great stuff!
My stock 2015 Yukon (5.3) has 135k miles on the original TC and trans. I just bought a GM Tow Package Torque converter (dual clutch like the ZL1/CTSV TC, just with 3 bolt holes instead of 6), to replace my stock single clutch TC as preventative maintenance. My trans still shifts like butter and has zero issues. I also bought a Sonnax Zip Kit, the trans go clutch select valves and a TECHM rebuild kit to put in as well. I have HP tuners and will stop the TCC slip 1-4, should get at least another 135k miles out of the TC doing this, we will see how the rest of the trans holds up. This was all about $900 all said and done with OEM trans fluid.
Where are you located? I’m about to go through the same thing and could use some
advice.
No problems after following this video.? I have a 2015 Denali 6l80e thinking of copying him
@@justinstatham6378 Kansas
@@tsahlee313 no issues at all, put about 15k miles on it since then, 3k miles of hard towing through Colorado hauling a camper to 12k feet elevation and back down. Zero problems except I did have to lock up the converter in 3rd and above when towing to keep temps down. Still never went above 200.
I'm so happy to see you back. I know these videos are a lot of work and they are very appreciated.
welcome back its so good to see you again.
WOW!!!!!! Hiram!!! Qué gusto! Saludos hombre!! Now on to the video!
Very interesting. I've heard good things about HP tuners for even viewing PIDs. I haven't had the opportunity to use it myself yet. I'm liking the fact I get to see some of the features and functions here. Generally not a fan at all when ppl tune, but it's understandable when a technician does it when they know what they're doing.
Thanks Cuba, It's a very powerful tool. Specially when you're trying to figure out air fuel ratio discrepancy. Paired with a wide band sensor and your scope of choice, you can quickly pinpoint issues with the issue you're trying to diagnose, fuel trims can be difficult to diagnose if you cant really see what you're looking at. It's an awesome tool, a good investment too.
In my case, instead of engineers trying to solve our industry transmission issues which are very obvious that never take care of, it's safe to say we can address the issues through this method.
Thank you for your comment, it's very valuable.
Good to see you back on here!
More to come!
@@AutomaticTransmission Hope so!! 😍🤩😃🤞👏
glad your back Hiram!!. i really enjoy your videos, i have learned a lot from you. you are the best on youtube. best wishes
Wow so glad to see you back. Love watching your videos. I would look back from time to time to see if you were putting out videos again. Hope you and your family are doing well. I look forward to more videos. I know it’s a lot of work. Thank you.
Dude, great to see you! no one like you anywhere on the AT's. so glad to see a new quality Vid....
Well explained info on the new era of chevy/ GM factory flaws! Keep up the good work Hiram!! Mr.Anderson - AndersonFam Transmission
Glad to see a new video from you!
I bought a HPTuner and disassembled DOD, E85 because the virtual sensor kept creating a positive feed back loop making the truck run lean. Then I disassembled the slip between 1-4 and increased pressure. Truck runs amazing and the power is fantastic and always ready. I didn’t buy the tuner for extra Hp, I just wanted to eliminate the BS systems.
Awesome, nice to see you again Hiram
Nice to see you back brother !! All them issues that’s why I’m glad I’m a tuner and I tune with hp tuners my self .
Right on, Send me the link to SEMA so I can post it on the next video.
Listen thank you for your kindness in transmissions this video help me on my truck good job brother
Oh damn awesome thought you were done! Welcome back!

We rebuild these all the time own a car lot always replace the pump the cover and bell housing gm part number on Amazon. Cheap. Never thought to use Hp tuners and look at converter lock I can't believe gm would grind on a tongue converter a factory one at that in 2nd. Thinks for the tip
Glad to see you are back with videos !! Very nice upgrades to those units. Thank you so much !

Por Fin! Hiram is back!
Got a video on 6L90? I just got a higher mileage ‘09 CTSV and really want to know what I can do to prolong the life of it was checking out the sonnax zip kit whatever I can do with the valve body/ trans tune to prolong the life of it. Changed fluid/filter immediately hadn’t been done in 50k..no metal..fluid was still red..pan magnet was very clean minimal material. Thanks! Love your content man
I'm a simple man, I see a new Hiram video, I click
Learning... Thank you for detail explanation....
When I got mine. I have hp tuners. Turned off DOD. And turned off converter lockup in all gears but 6th. And shortened the shift times up just a little. Haven't had any problems shifting since. I used to have shift flares bad.
wow, after 2 years, out of nowhere...
i really hope you see this comment. i have a 2011 avalanche 5.3 6 speed so 6l80 trans. my issue is under quick acceleration (needing to get on freeway, or pass a car) i notice trans will "stutter, grind, and RPM will red line without shifting to next gear, unless i let off accelerator and then ease back into pedal, i also have 205k miles on the truck. im really hoping that a new TCM (trans valve body) will fix the issue. after watching this vid now has me concerned that i may need to take to trans shop for 1-3 clutch plates bad... idk yet havent dropped pan yet to look for metal. im just doing the research to fix this in a one and done.. i have heard these are known as GM throw aways. i fell i can rebuild the tcm valve body but if it exceeds that and is more internal trans issue then ill be forced to take to shop. 1 shop told me that it would be 4k minimum for new that i cant rebuild, mind you this was just over the phone he never drove it, looked at it, or put a computer to it.. please help point me in the right direction or message me and we can talk 1 on 1.. please i need help
Woohoo! Welcome back!
glad to see your new video again:)

Woah been a long 2 years waiting for a new video. This is exciting
More to come!
I ended up going all sonax valves but left the previous builders transgo clutch select. But my transgo tcc valve stuck open and smoked my converter. But I know transgo is a great company when I pulled the tcc transgo valve it was stuck
Sounds logical. But what I've seen a lot is the other way around. The converters failing prematurely and debris sticking the valves, usually the compensator feed valve which it sticks very easily. I've had converters shuddering right off the bat before even delivering the vehicle to the customer, Sometimes after a week or 2. Some on the 10 day 300 mile check we ask our customers to bring back to recheck that everything is going smooth.
I do agree that Transgo probably need to update that and other valves adding lube grooves to make them a little more stable, specially where they added the extra material.
@@AutomaticTransmission yeah I found tcc control valve stuck put new pump and upgraded to sonnax tcc apply valve on the pump works great I’ve been running it for 600 miles so far . But the shudder for back see what I sent you and that help you if I’m out your way I will stop by and show you . But you can look back that will fix shudder
I just did one this week, it worked good. I'll post it later. It keeps the TCC right at 0 slip RPM's. I did the normal TCC tuning added your advice and did a complete trans tune on it. I'll go through the whole tune on the video. Maybe I understood wrong, once I upload it tell me what you think.
Thanks again.
Hey Hiram, great to see this video. Just inherited my late fathers truck and looking to make it reliable. Is the HP tuners portion something that can be done without changing TC and not using the kit? It’s only got 50k km and I’ve already used the range afm disabler. Will also be getting the cooler thermostat upgrade. It’s a 2018 Sierra. Thanks!
Excellent information.
DAMN, I WAS SWEATING JUST LOOKING at the PARTS😒
long time no see, thanks
Thank you too, I had a little breather so I thought of you guys.
Been extremely busy lately.
Love your videos and your g35. I've got a g35 I'm parting out. Motor blew, no title, good 6speed trans tho and everything else if you need one or know anyone. Cheap. In s.e. tennessee.
Welcome back
Thanks bro
Where is your shop located??
How can I get one of your 6L80 rebuilt units for my 2011 Silverado 1500 4wd
I know it makes since to apply pressure to the apply ramp but it actually does nothing . You want to make those changes to regulator gain moving gain up or down adds and subtracts pressure but very small increments. And regulator offset Is lock up pressure the more you add to to offset the harder it will lock up or engage. Helps with dragging converter . If if you want to check my advice creat a table in your scanner mirror you apply ramp table . Making changes to ramp table will show no change but when you make changes to your regulator gain again small changes you will see pressure changes positive or negative. Moving the regulator gain up actually removes pressure and that helps with shutter. Always again thanks for all the videos .
Awesome,
When you say regulator, what table should I look that under?
As you know these things are known for shudder issues. What I've been doing has worked great so far but the more information to add would be great.
This video only shows what I do to TCC issues. I actually do a full tune on some with some manuals I have.
It seems you're more experienced with tuning than I am. I do it as a hobby on my own vehicles, cams and stuff. And what I've learned so far to improve my transmissions at shop has really helped me a lot.
Any input you would like to share would be appreciated, not just for me but for others that have the capability of doing it as well.
Thanks bro.
@@AutomaticTransmission look under the apply ramp table it will have a regulator gain table normally set to 1.5 and a regulator offset table that’s under that one in PSI. So try one day after your done building make your changed then add a little to the regulator offset table you will se it make the converter apply harder and faster with out dragging. And regulator gain the more you add it actually goes backwards so it takes pressure away and actually helps the converter stay locked with out shuttering and great for higher stall converters .
Awesome, I'll try that on the next rebuild.
Thanks, I really appreciate that.
I'll try and post a video of it and give you credit for it.
@@AutomaticTransmission haha credit is all you . You’ve been a huge help I rebuild my 6l80 with all raybestos and Sonnax 3200 stall built by Britians parts in Houston by Robert who I’m sure you know . All the apply pistons plus pump and valve body I completely rebuilt it with sonnax and transgo . Yes it’s pretty amazing . God Bless
I have missed your videos
I just bought a 2013 Suburban 1500 4wd 5.3L. Can I use these exact tune specs on it or is this only for a replaced transmission with the new TransGo valves? Thanks
Very informative video. You seem like a very intelligent transmission mechanic. My question to you is this. My transmission is doing fine so far at 45,000 miles. What can i do to my 2017 silverado 1500 6 speed tranny to prevent a future failure without taking it out of the truck or removing the DOD ?
Have you guys seen any of the GMP Supermatic 6L80’s yet? I have one going into a g8 right now, just curious if you have seen any grenade yet.
Brother been missing your posts!!!
Sonnax claims to have a converter with an updated front cover to help with the deforming issue
Yes, they do.
Hello.
so wanted to see what you think.
2017 Chevrolet Express van extended.
6.0 I believe with 6l90e
When cold slowish goes in gear or moves forward. With a sudden moderate slam into what I believe is second gear ⚙️.
Then drives like normal if still driving like say from parked to a main road where there are no stops.
After stopping at stop. No forward movement. Unless light throttle is given ever quick but slow tapping of acceleration pedal will slowing moved forward.
Engine light on but says fuel system code. Related to someone trying to steal gas. Damaged something.
Not sure if it's related to drivability issue.
Currently waiting for warranty process.
The drivability issue came on suddenly. One week ago.
Has 87000miles.
Let me know what you think..
Wondering why the factory doesn't address these issues at manufacturing new units
Can you make the changes using HP Tuners without doing anything physical to the transmission?
If there's no issues with it yes you can. It will improve and make it last longer.
Dear sir, could you please advise. I have stock 6L80 on my 2011 chevy camaro SS. I found UPDATED Valve Body Spacer Plate w/ 8 Check Balls 10-Up. Can I use it on my stock car?
Hiram, great video. Especially the computer corrections. Which PTC converter do you recommend? 6L90 version? Do you update to the latest GM cal before making TCM adjustments? Thank you for sharing.
Just did a service on a 2017 5.3 6L90 with 100K miles. Never been serviced. Filter restricted. Small metal debris field in rear of lower section of pan (1/2 by 2") Trans still a little herky jerky so deleting the DOD and adjusting TC parameters is definitely needed.
AWESOME, your back. I'm in the automotive trade an I had learnt so much from your previous videos about transmissions! It's great to have you back!!!!! Also will these mods work on 6L90?
Yes, 6L45E, 6L50E, 6L80E and 6L90E.
What state are you in? I just installed a GM reman 6L80 in my 2016 Silverado and it has a shudder from 1 to 2 and 2 to 3. Torque slip acrual and desired are 500 rmps apart. Bad converter right from GM? I took to the dealer i bought it from and they said until the check engine light comes on they wont do anything. The original trans failed no warning or lights!
Question: Can the TCM torque converter lockup tuning be completed on a STOCK 6L80 ? Or does it need the transGO hardware installed first ? Thanks !
Yes I did it at 114k miles on my 08 Yukon Denali. I have 179k on it now and no issues. I also change my fluid on time though. Drive it like I stole it every chance I get😁
Hi sir, I have a 6l80e on Chevrolet Silverado 1500 2015, which springs should I use for the clutch select valve? The black ones or the original ones. Transgo 6L8 CS-TCC.
Valve body takes 8 check balls but this Third-generation. You said not to install black spring on the 4th and 5th generation.
My truck is third generation but it has 8 check balls in the Valve body. Sorry but I am a little confused here.
This great video. To this issue. I have shudder in downshift from 3 to 2 or from 2 to 1. I will follow your instructions regarding the hptuner. I hope this will solve my problem. I have a 2015 Tahoe 6l80 transmission. Using hptuner only will solve the problem ???
@Automatic Transmission14 Silverado.. Truck wont go past 12 mph when cold... reverse is ok. What do you think 106k Valve body kit throw in a Jasper? What level scan tool do I need to sync the TCM? Never drove hard DoD was turned off... Engine will rev high vehicle speed 12mph..
Ok, So here's my question. Do you or would you change the tune on a 2008 Chevy Silverado 2500HD (2wd) with a 6.0 LY6 engine with the 6L90 that doesn't have DOD. We are currently getting ready to rebuild the 6L90 that has puked. And want to upgrade EVERYTHING in this transmission since it down and we have the transmission out. Including replacing the OEM converter that seems to be one of the leading causes of problems with these 6L transmissions.
