Welcome back! We are finally covering the 6L80 Thermal Bypass Mods. There are 4 unique mods that we will be covering in this video including the updated GM Thermal Bypass, the Pill flip, Drill and Tap, and Super Solutions retrofit.
Important note for transmission fluid level check:
I contacted Superior Transmissions and the said the proper way to check the fill level with their modification installed is with the truck running and the engine at operating temperature. For me, the engine operating temperature is around 210F. This is different than the procedures found in the GM truck owners manual. Please contact Superior Transmissions to clarify the correct procedure for your specific vehicle.

I have a 2017 Sierra crew cab 4x4 with about 35k miles on it. Will definitely do the update to hopefully give it a longer life. I may replace the o-rings on the lines at the same time for a safer measure. I have heard of times where reusing old o-rings may not seal correctly leading to leaking.

Currently in the process of doing this upgrade. I live in rusty NH. I was able to get my old thermostat out by doing some PB blaster after I got the snap ring out. Let it sit for like 30min. Tapped the top with a hammer and punch. Then I used some map gas for about a minute. The thermostat slowly pushed itself up and shot out like two feet into the air, so be careful.

Nice video. Just did my STL010 install. The front driveshaft blocks access, so I removed the 13mm bolt first to separate the block from the case and then could flex the pipes a bit to get good access to the 10mm bolt and pull out the pipes. The old innards were not coming out of the block so as someone else said, you can use a screwdriver in the upper side hole to get the old piston moving up and out. Reinstalled, used a new gasket, no leaks. This is one of the must does for these transmissions. The other being to reprogram (e.g. hp tuners and vcm suite) to prevent torque lockup in 1 through 4 and 0 rpm slip in 5 and 6.

Thanks for this information. I watched this vid several times this past week in anticipation of doing this to my 2014 4WD Silverado after the upcoming easter holiday. None of the local mechanics wanted to touch it. It's a small town so there's only a few. The truck also needs the transmission fluid and filter changed. It's cold where we live and I don't drive this much - 48K miles on the truck - but the past two times I drove it to town it started to wobble for a few seconds when shifting after I hit the highway. I thought it might be tire related but after doing some research I found out it's likely the torque converter. At any rate, I had to order everything including the tranny fluid. I plan to install the kit first and then drain the pan and as much fluid as I can before I remove it and change the filter. I also ordered a replacement pan with a drain plug. I'm hoping changing the fluid and filter fixes the torque converter wobble. And I assume the bypass kit will fix the high operating temperature.

@Go69 2 жыл бұрын

The ONLY thing that is going to save your 6L80E transmission is to remove the factory GM TRASH torque converter and replace it with an after-market, welded together inside, billet torque converter. Otherwise.... if you don't do that... there is NOTHING on Gods green earth that is going to prevent torque converter/transmission failure. We build MORE of these units every single day, than any other transmission. I'll give you a hint.. It's not the heat that kills the GM converters.. Cut one open and you will see immediately why they fail. It's because GM set them up at the factory to fail... to generate more $$ for themselves. Every unit we rebuild, we install our own by-pass valve that we manufacture here at our shop along with a Precision BILLET torque converter. For those of you that want to do this thermostatic block mod-I sell the valve for $5.00 + shipping. You can install it in under 30 minutes. It will guarantee that ALL fluid will go out to the cooler, and then back to the transmission, with none of the hot fluid being recirculated. It will NOT stop your GM torque converter from failing though.. he gives GREAT information-SWAP OUT THE GM torque converter! Do it NOW if you have not already done it! Or if it's not too late? We have FAILED 6L80's coming in as early as 60K miles.. with many in the 80K mile range, and a lot in the 120K range.. If you wait to remove the GM converter-you may come to regret that decision. To get the thermostat OUT of the aluminum housing-come in at a 90 degree angle with SIDE CUTTERS and squeeze them such that the jaws are bitting into the nipple in the center, and then push the handles down against the thermostat body, thereby lifting the plug out of the housing. Just be sure the sharp jaws bite into the nipple on the plug, and then it will come right out. It does not hurt to use a little WD-40 to get down to the O-ring before prying it out.. But even without the WD, it will still pop right out with the side cutter sharp jaws biting the center nipple.

@Go69 2 жыл бұрын

@@bendino9016 Are you sure you have the 6L80 or 6L90? It was still possible to have the 4L60E in 2011-IF you have a 4.8L engine. If you really got 225K miles-then rejoice and be happy as that seems to be a pretty rare occurrence. Not impossible, but fairly rare. Keep in mind as a shop we ONLY see the ones that fail, and most of those are coming in as early as 60K miles, with the average being between 115K-125K, and sometimes we will see them as high as 175K... But... there must be a bunch of them out there that are doing better mileage wise... but we don't see them.

A late entry, but maybe it will help someone glancing through that has seized internals in the housing. If you look on side of housing there is an allen screw. When removed it reveals a port where you see thermostat spring. You can use a small flat head to pry internals upward. Just keep hand over top cause internals can pop out suddenly.

First off, thanks for making and sharing this video! GM's replacement valve (86774933) had smaller ports for the hardlines than the valve on my 2020 WT, but the hardline fittings were the same style (no retaining clips). The ports for the hardlines on my valve appeared 2mm larger in diameter. You can swap the internals between GM's replacement valve and the one I had, but I ended up going the Superior internals route instead. The valve on my 6L80 was not stamped with a 70. Also, the o-rings for the hardlines are critical since GM just retains the hardlines in with the metal bracket you mention. If you accidentally mess one up like I did, you'll leak transmission fluid like a sieve and be unable to drive the vehicle. I couldn't find the OEM part number for the o-rings so I just went with what appeared to fit (and was temperature rated), but adding teflon tape around the hardline lip (especially in the inlet port line) works well for a makeshift gasket.

I am going to run the trans as long as it is working good but after that I will be changing my torque converter to the 8L90 one and installing the upgrade kit made by Sonnax. That kit has very good reviews and from what I have read and also talked to others about it the claims are that it makes that trans almost bullet proof. I have replaced a lot of things on this truck but instead of replacing with oem parts I have gone with all upgrades especially on things that are known to be issues with these trucks.

I used the Superior Solutions kit because my 2014 Sierra 1500 has the first design valve with the clips and I didn't want to replace the lines. Before doing the modification the trans temp ran at 190 to 195 with no load on the truck. After the modification it runs at 150 with no load and I just got back from a camping trip towing a 24' camper. Going down the road at a steady speed with the trans in manual 5 and using the tow mode the temp stayed at 170. The highest it got was 180 while going through towns in traffic. Even if you don't load the truck or tow with it, it's worth the investment. I just wish you could purchase the kit directly from Superior Solutions. I was able to find an actual transmission shop online to make my purchase because I've had bad experiences with E Bay.

Cliff-thanks for this video. I went with the Sure Cool STL010 and it works as advertised. I installed this yesterday on my 2014 Silverado LTZ. Prior to this install, my transmission routinely ran at 192 degrees on the highway; I just returned from a 50 mile round trip and it ran between 144 and 149 degrees on the interstate at 70 mph (outside temperature in the low 80’s); highest reading in stop and go traffic in the city was 158 degrees. One word of caution for those with the original bypass with the wire clips like Cliff shows in the video; pay close attention to the orientation of the clips when you remove them; they only go on one way and if you don’t get it right, the lines will blow off the bypass and you will have a mess in your driveway (learned that lesson the hard way). Other than that one issue, very easy install and I am hoping it will make my transmission last much longer.

I have done the "pill flip" on my 2017 6L80. I'm not sure if I understood your term "bypass is always closed" correctly. My understanding is, when flipping the pill, the bypass is aways opened, allowing the transmission fluid to flow to the radiator cooler all the time, with no shut off. This will allow your transmission to run much like the older generation transmission 4L60. My truck transmission now runs much cooler (120-155 deg F) all the time, even when I go from 2000' elevation up to Mt Mitchell @ 6684'. HEAT KILLS TRANSMISSION FLUID, which in-turn, will wear out your transmission. Thanks for the video, it's very informative & I hope that I didn't post incorrect info.

When you remove it I’d use a 10mm socket with an extension place the socket over the center of the bypass Make sure everything is flat and square on the table, give it a good solid tap with a hammer a couple of times and that should break it loose. With the good pair of needle nose pliers or lien men’s pliers that bypass should come right out w/no problems! I had a similar situation when rebuilding an old Harley engine trying to remove an old woodruff key that was fused in tight and when I tapped it a couple of times w/the hammer it popped right out!!! Better luck next time!!! Great video very helpful! I need to do the same thing on my 2009ltz Silverado. I love this stuff! TY

Or an air compressor blow off gun with the rubber tip on it and jam it in the higher port. Shop towel in your hand over the part so it doesn't shoot into low earth orbit. That's how you free a really stuck brake piston. May have to plug the lower port if the check allows reverse flow. Also that drilling at the top of the cavity can very well tear an o ring on install and cause leaks now or later. Not internet BS, I've got 5 years of hydraulic manifold design in the books and I've seen it a lot. Either way thanks for the video. I didn't have mine apart and wanted to see the cartridge assembly.

Thank you for the shout out on our very unique Sure~Cool® systems, nice video, thank you! Superior’s TransLab Engineered Sure~Cool® systems technology is patent and patent pending. Our Properitary designs STL009 / STL020 (ford types) and the STL010 for GM6L80/8L90/ L5P Allison uses a dynamically active Lube~Loop™ that keeps the bypass full flowing / open on startup, and still provides a safety bypass system that will Lube~Loop™ back to the parts and internals. You plug it, or Flip a pellet, what you got? A nightmare if the system ever needs to “kick the Bypass on” when needed in cold temps or any restriction to flow from the coolers and lines… our system uses the viscosity (thickness of ATF / Oil ) when extreme cold temps experienced to unseat the ball and allow bypass oil back into the transmission until flow rates stabilize and resistance to flow is overcome.

@@superiortransmissionpartsi5357 I just installed your kit today and rode around town this cooler evening. I was averaging 170’ish with the GM 150’ thermostat and hit 144’ this evening on my quick test with your kit. Hoping it stays this way tomorrow. Quick question: If my radiator is running 190’ from the engine heat and my tranny fluid is ‘being cooled’ by the radiator, won’t the engine heat conductively increase the tranny temp on longer runs?? Somewhat of a backwards way to look at this issue but I’m not positive that this can’t happen. Thoughts?

@superiortransmissionpartsi5357 Жыл бұрын

@@Sax6thAve123 you are correct, on vehicles with the in tank (radiator) trans cooler are actually a heat exchanger. It dissipates heat to the cooler side. OR warmth to the colder side (In colder temps) and in cold climates acts as a pre-heater to the transmission atf passing thru the heat exchanger/ in tank cooler. In hot weather the trans cooler will run about 175 or lower as the secondary air to air cooler is now cooling both, mainly the Transmission and what I call scrubbing off the the difference of temp from eng vs transmission. Also the air to air cooler needs to be 2.5 to 3 x larger in sq. Area so you have better heat dissipation thru the fins or plates of the external cooler vs. a heat exchanger via the tank.

The transmission went on my 2013 Sierra at ~184,000 miles. The trans was slipping, and then overheated within 3 miles of where I was taking it. The trans was rebuilt, the torque converter was replaced, the TOC lines were replaced, the radiator was replaced and so was the external TOC. I haven't had a transmission go in over 30 years so it was a shock when it happened. I am religious about changing trans fluid every 40,000 miles, but even that didn't help.

What a joke. It definitely brought my temperatures down to 125-150 degrees but I think my internals took too much damage and so now the temperatures fluctuate depending on the temperature outside. If it's cold, it runs great. If it's hot, it kinda struggles. I also installed a Mishimoto Trans-Cooler and honestly I believe that's the only thing keeping my transmission from blowing.
