trans tech of 45 years. built performance transmissions for racing for about 20 years.have done a lot of tuning in my time. this video vas extremely informative.and helpful thank you so much for taking the time to put this out .

[@KCDUBZ124]

I'm glad cleet plugged your channel Matt I'm very new to tuning and I appreciate the time you take to teach us how to tune

[@pigg82]

You are exactly what us tuning/hp tuners newbies need. Thank you, subscribed, and will be watching everything

[@stevensmith3291]

Would love to see an 8l90 video. Awesome stuff man keep it up

[@ArnoTrek]

I plan on buying HPtuner next week on my stock 14 5.3 for future mods and this trans tuning guide for annoying clunky shifts and extending trans life is a great starting point. Thanks again.

[@jaydubb71]

I used to disable Torque Management in my G8 with 100-200ms shift times. I broke SEVERAL driveshaft to rear diff flange bolts. It would chirp tire all the time BUT every now and then... SNAP... HUGE VIBRATIONS. I learns the hard way. LEAVE TORQUE MANAGEMENT ALONE! You're welcome...

[@NVETHIS]

Wow, wow, WOW!!! I recently did a front-end maintenance/replacement, 7.5 suspension lift with Coil-Overs (front/rear), kicker bars, and 35-inch tires. I did the gear/tire converter, but it's been running like straight garbage since. I watched this and its Super informative and goes in depth with explanations. I did the stock settings for 6L80 with Bluecat as explained in this video and the WOT for a stock Gen IV. All I can say is WOW! It is a night and day difference. It drives so much better now! Gained a new subscriber here! Thank you!

[@dreece2000]

If anyone does this to their truck with a 6l80 be warned it will make the truck work like its supposed to. What a night and day difference thanks for sharing this matt. So many different things I didnt know that many parameters was changed by the tire size. I cant thank you enough

[@tonyray518]

Brand new to tuning but your video is so clear and explaining so well im super confident in tuning my 2018 silverado. Thanks for the video man, i cant wait to dive in!

[@jtsperformanceautomarine]

Glad to see even an expert occasionally forget to disconnect the scanner before flashing 😅 Solid information man thank you for sharing this with us.

[@Straightshot75]

When you say disconnect, do you mean physically, or just stopping the scan and disconnecting from the scanner?

[@Straightshot75]

Love the video, and don't worry about the length of the video.

[@jtsperformanceautomarine]

After taking a data log with the scanner you have to click disconnect from vehicle before you can go back to the editor and write any changes. Do it a million times but still forget occasionally and have to flash back to the scanner to disconnect lol

Dude this is one of the most informative videos I've watched. Liked, saved and subbed.

[@ericharmer]

Great video again. I keep coming back to it as my xp grows and I have a more question that is answered by it.

[@dirtyred9225]

On the tire size dilemma, I just keep a tape measure handy. No tire has been true to size that I've seen yet and doing it this way has been correct every time on speedo.

[@Matt_Sanford]

It isn’t a dilemma. How I said I do it is the way I found to be correct, every single time. I have verified it via GPS on every vehicle that I’ve tuned since I realized it probably 11-12 years ago. So that was more of a tuning tip. You can choose to do it that way or not.

[@dirtyred9225]

@@Matt_Sanford I was just adding to your tip as the difference in actual size vs advertised sizes differs from brand and size. Some "35s" are 33.5 and some are 34.5 and grabbing a tape takes all guess work and calculators out of the question.

[@lsxjunkie]

Great video! Love you content and ability to dumb something's down and also take it deeper into the psi presets and torque management. No psi adjustments on the shift psi tables? Looking forward to more videos on trans tuning. How about a quick video on scaling a set of say ID1300s or 1050s

[@ericharmer]

This video was transformative for me. Ive been struggling with my 6L90 for years, and after using this video as a real-time instuction guide and then doing A/B tests I feel I have a much more solid grasp on the tuning process and the car has never been more fun to drive. I only wish this video had come along years ago! Thank you, sir.

[@blackchallenger]

Great content! This helped me so much. Stoked for the rest of the Gen V stuff

[@Labergemusic]

I have a 6l90 + HPTuners so this is gonna be a good one for me. Edit: I'm 3 minutes in and boy am I glad I got to this video before I started really figuring stuff out. Edit 2: woohoo I went for my first drive. Got some throttle response stuff to figure out and maybe more tire size adjustments. Good stuff, I'll eventually watch more of the video to see what I might want.

[@MJL1776]

How did the tuning go with the 6l90? I'm thinking of getting this for my truck but video is on 6l80 just curious is everything is the same?

[@Labergemusic]

@@MJL1776 I haven't gotten far enough yet. I read my PCM, downloaded the tune, but it didn't show any of the transmission settings you see after like 4 mins in. I'm going to assume that my trans isn't reading, or I'm missing something. So, not far yet.

[@Labergemusic]

not that anyone cares but I found the missing 12v wire and my trans read perfectly. it needs power after all.

[@MJL1776]

@@Labergemusic how did it turn out for u? Did everything from 6l80 video basically the same for the 6l90?

[@Labergemusic]

@@MJL1776 Hey man, just went for my first drive. Yes everything from the video applies to the 6l90 transmission. I have a lot of tweaks to do as my gas pedal was swapped and throttle is weird but I'll tell ya those shifts are solid. A light thunk into gear you can tell the slip is gone. If you're putting a gen4 in your car, you're going to want to ground two yellow wires (yellow and yellow black). One is the starter relay control and the other is the powertrain relay control. If you don't either the engine won't fire or the trans will be in limp mode. Ask me how I know ;) Good luck!

[@squarebodyseth5986]

Runs amazing, little quick to downshift but a little adjusting to bluecat and it'll be good.

[@squarebodyseth5986]

Might be nice for towing I'll have to see how I like it with the exhaust back on it.

[@nikhayes3396]

Hey... Did I talk to you on the phone a few years ago. I bought a wiring harness from a guy and he had me call a guy named Matt in florida and I sent you the computers off of my LS engine. Your voice sound familiar. I still have that engine with very little time on it, I had a joker help me mount it in a W4500 sweeper truck, and the guy made me "custom" motor mounts that broke right away. So its just been sitting. After Covid killed my street sweeping business. Quite sure you are the guy that tuned my ecu and tcu

i used blue cat for my truck norris cammed 2011 2500HD with a 6L90, drives really good under normal circumstances, 1-2 and 2-3 WOT shits are fine, 3-4 WOT bounces off the rev limit and never shifts. if i let off slightly it will then shift.

[@chusunderworld793]

can you explain more with the gen 4 and gen 5? are we talking about the generation of silverado or the transmission?

[@fildavis118]

Super informative videos! Thanks!

[@lordoftheturps9337]

How much do you charge to tune?

[@JerseyFrank007]

Excellent content! Question.... What about the purge enable function? Us guys who add to the clutch stack up on the 35r and 456 clutch packs....we get kinda tight on tolerances. Gm hard wired a clutch purge to happen on every new drive cycle just after the 2-3shift to quickly apply the 456 clutches assuming to purge air (?). Well that causes a small "bump" or bindup which totally sucks. So disabling the feature prevents this function. Thoughts on this solution??

[@Matt_Sanford]

I never recommend adding to clutch height but you will find that making oncoming and off going pressure changes as well as adjusting minimum volume can help to resolve your issue.

[@JerseyFrank007]

@@Matt_Sanford Interesting.... Thanks for the perspective.

[@chanceshaw5001]

@@Matt_Sanford I wasn’t sure how else to tag you, so ignore that this is under another comment. The ONLY “complaint” that I have about these videos, is for example at around 32:00, you explain that you don’t typically change it but not exactly what the shift inertia is. Ps this coming from someone with no knowledge, I.E. I’m not sure if it changes how hard it shifts based on speed or throttle position or what. I say ‘how hard it shifts’ because you mentioned it’ll be more ‘rowdy’ with increasing these Other than that specific “complaint”, these are some AWESOME videos and I love that you’re putting them out there

[@boxoftj1]

In semi trucks, I know actual tire diameter is not the driven tire diameter because of just normal tire flex. I know my actual land speed is different when I'm empty versus fully loaded.

[@macklyons6970]

Thanks for the video.

[@mckeemarkings]

Thanks Matt. I've been dealing with a Gen4/6L90 in a swap for 6 years. Part throttle 2/3 noses over but WOT seems find. Engine and trans are completely stock. I've struggled to figure it out. Watched the video multiple times and am just not sure if it's an oncoming pressure issue or TM. Seems like TM but nothing I do seems to help.

[@davidstruckoff]

Hey Matt, great video and it's much appreciated for the help, advice. When you reference Gen4/5 tucks, what model years are those. I googled, and its showing compeltly different then what I'm understanding. I have a 2014 silverado, trying to figure out what Gen it is so I can follow along with your recommendations. Also, I put in Transgo SK and TCC kit along with a Circle D Torque converter stock stall. Would this setup still be considered "stock". Stock engine, stock exhaust.

[@leftyeh6495]

I recognize you from Cleets channel, but I'm only here because my 6l90 too a dump and I need to know how to tune for the new one to not trash the converter.

[@wiskyd]

Love your in depth videos. Have you tuned a 6L80 with mods? I have the sonnax zip kit, billet pistons, and transgo kit for the pump.

[@1fastbuggy502]

Do you do remote tuning ? Or can I send you my trans file to get retuned. No help here in Canada. H2 Hummer with heads and cam. Installed a 4L80 with PCM wiring adapter.

[@tonyray518]

I went from knowing nothing at all to a fully tuned truck in the matter of a few days by watching videos waiting on my tuner to come in, literally no joke. But it was intimidating until got it flashed the first time turning off the DOD only just to make sure everything was going right!

[@Richard-lw9cd]

I noticed on your first drive the desired slip is showing on the scanner as 4.5 rpm even though you zeroed everything out. Any idea where that desired 4.5 rpm is coming from? I have the same truck in 2017 model and it is showing 4.5 as well after zeroing everything out.

[@Matt_Sanford]

That’s hidden parameters that HPTuners hasn’t defined. I haven’t had it cause any issues though but yes that’s not something we can eliminate at the moment until someone can find it in the binary file and add it to HPTuners or add it into user defined parameters.

[@Richard-lw9cd]

Thanks for the explanation.

[@treybadd]

You sure about the TCC apply ramp rate? It says " this is the apply pressure RATE for the TCC...Its a rate, it will be faster with a smaller number. Siu automotive tested this also. He increased it be 30% and it had a slower time with less pressure. Lots of conflicting info on that chart for sure.

[@sekouchill]

What happens if you put a stall higher in your trans tune than you actually have in the car?

[@scottmorris8821]

Matt, does this get rid of the “pop” these trucks do when shifting at or near WOT?

[@dougkurtock9911]

Great video, thanks for sharing! Any reason to keep the TCC unlocked in the WOT tables?

Most of the time, the truck perform better at WOT when unlocked.

[@cpwood2888]

would I lower the oncoming pressures and increase the oncoming volume to stop a shift bind? 2-3 clutches are too tight when rebuilt(guess). I'm getting close by increasing the volume but the reset causes terrible flares until the adaptives start kicking in. About a week or 2 later she starts to shift harder. I never liked that it had to flare until the adaptives took over but what you said at the end made perfect sense about the adaptives telling you "no dummy that doesn't work".

[@Matt_Sanford]

The trick to getting one not to bind is to watch the datalog and determine which part of the shift is causing the bind. If the flare is bad and then it binds after the flare you would increase Oncoming and decrease Offgoing. If it binds then flares, you would decrease Oncoming and increase off going. This is actually the reason why I don’t like clutch height being altered from factory but you should be able to get it dialed 👍

[@cpwood2888]

If I set it back to factory settings it doesn't flare that i can tell. The shift is violent and the final shift time is 75 mil sec. I then understood lowering oncoming volume would reduce flare so tried increasing until it started to flare. the adaptives then slowly bring it back to hitting like mike tyson. I tried lowering the oncoming pressure and it seems to help little by little but unsure if I'm doing something terrible to the internals. @@Matt_Sanford

[@cpwood2888]

The shop swears up and down they set it to spec but I've exhausted my tolerance and probably going to take it in and make them verify the clearance. the stock tune file binds which 2-3 flares more often than not.@@Matt_Sanford

[@carguysshop287]

So tuning the slip speed on the torque converter down to a minimum…. Will this fix the The 8 and 10 speed transmission converter shutter? TSB says the fluid exchange fixes it but I’ve seen many that the shutter comes back

[@roderickvinson3425]

Yes used it on several 8 sp that where shuddering so bad one flash like a new transmission

[@wizzoevo8103]

Is that half inch of tire diameter only for correct mph? Does that little bit change shift characteristics to the point where you will feel a difference?

[@Matt_Sanford]

Yes it’s to correct mph. No it won’t change shift characteristics whatsoever.

[@treybadd]

Is disabling lockup in 1-4 a good idea or is it better to lockup and command no slip?

[@Matt_Sanford]

Just depends on the application. Most applications I set them up to lock up in 4th and above with no commanded slip.

[@treybadd]

@@Matt_Sanford daily driver stock 6.2 2012. Denali. Trans just rebuilt with sk6l80 and sl8-cs-tcc kits from transgo and they supplied a precision billet converter. Occasional towing and spirited driving. I haven’t used hptuners yet. Im still in the learning all I can phase. Did you watch the video series SIU automotive put out? The ones where he installed transducers in the valve body of a 6L80 then tested on a dyno and experimented with how different parameters actually change things? It’s pretty cool.

i have a 2014 with the same OS and triple disk but with a tsp stage 2 cam and 33.5" tires and 6" lift. i have better lockup leaving the offset and regulator gain stock. going to 1.5 and 90 in 6th it shudders horrible. allegedly gain and offset is divided which would make stock 70 pounds and the 1.5 and 90 makes 50. ive also heard the apply ramp is actually apply time. maybe i have something misunderstood?

[@paulcondie2520]

Where are you located? Thanks

[@BigEbikesports]

Putting in 0 slip causes the TCC to shudder/fishbite worse and will eventually destroy the clutch faster, they are designed to slip but poorly designed, flawed from the factory. GM did this more on Gen V to meet mpg with the EPA. the 3 rpm minimum slip on AC creates a lot of shudder and issues. The oem torque converters are defective from the factory because they do not have enough area of friction and warp from heat in their design. The only fix is to replace torque converter with a billet converter that resolves this area overheating and friction. Also from 2014 6sp and 8sp trans have a built in cooler line thermostat causing the transmissions to run at 195* F before opening. You can flip the pill and spring inside to make the cooler lines flow all the time. Set all your slip rpms to 20, only time you would put 0 is if you have a tripple disk converter but you will also have to change other parameters to get it to stay locked. Some GM operating systems as we have found out in HP tuners will not keep the converter locked. Working in a transmission shop and tuning with Hp tuners I have seen a lot worse issues with people trying to 0 these slip tables out. It will make your factory junk torque converter grenade faster...

[@frankm4611]

I ate two circle Ds on mine before I went back to an upgraded stock one. Sucks cause I’m pushing a 6.2 l86 and a whipple. So it leaves a ton on the table. Trans is fully build to hold 800. And now it feels like it’s about to finish this converter off after a year. The amount of time, money and research I have into this trans is depressing. It’s smiles not miles right.

[@BigEbikesports]

@@frankm4611 Gm built one of the best engines in the gen V motors but their transmissions suck ass lol. I am currently running a circle D twin disk in my L83, I keep 20 rpms slip in every gear and so far no problems at last oil change at 80k miles.

[@Matt_Sanford]

They still slip with the setting set it 0 slip. It just has the ECM PWMing the converter to attempt to maintain lock versus chasing a higher rpm slip. I have literally tuned over 10,000 6L80es this way as I travel to transmission shops in the morning and tune all of the 6L80s. Of ALL of the years of working with transmission shops and converter builders… you are the ONLY one that has ever made that statement. I have personally put over 500k miles on my own personal 6L80es with TCC slip set to zero and those trucks still have the factory torque converters and transmissions.

[@frankm4611]

For me, it hasn’t mattered either with some slip or zero slip. I will say that the video helped with the shifting a ton. Can’t thank you enough for that. It was good before but now it feels like it’s putting more power down. Best time on my draggy was 5.5 0-60 now I would expect it to be much closer to 5.25. But my converters…. I’ve tried every thing I can get my hands on. Every video I could find that makes sense. Paid for books and even a few “experts” still have bad luck with the tcc. Has all the hardware goodies short of a dedicated drag truck too. Even with this video I have tables that don’t match with yours and all the others and so I have to make compromises or estimate what it would be, with my fingers crossed. But again, I’ll keep watching, this video and the burn-out one helped a lot. Thanks

[@Labergemusic]

So I got around to trying bluecat and when I did the tune the car went straight for 6th gear no matter what I was doing lol. Clearly I messed something up hahaha I had a feeling the numbers I was adding to the table didn't add up but I'll try again later. It's easy to write the old tune anyways.

[@tonyray518]

Would i have to do anything different if I have dual exhaust with flowmaster super 10 and 3rd cat delete? Also planning on doing CAI and speed engineering longtubes with the 6.2 intake swap.

[@BlumpkinReciever]

So i built a 408 stroker for my 2013 Silverado 4x4. Has stage 2 btr truck cam, ported 823 heads, cai, and long tubes and full exhuast with no cats. Ive got the tune on the motor pretty good but would like to smooth out the shifting. I chose the cam so i could use the stock converter and maintain my lower rpm torque for towing. Aside from zeroing out tcc tables do you think im going to have to use the blue cat software as well or do you think just the first step will help out? Very novice at this tuning stuff so any help is greatly appreciated.

Absolutely. That always needs to be step #1.
