@@kevinlister5424 I’m just here to help 🤙🏽🤙🏽. I’ve had people say they can do it on car! I’m glad it worked for you. Your transmission will thank you and so will your check book. Have a great weekend!

@@Jason-ht6ze you have a 6 speed but it’s the part STL010. The process is very similar

Directly from their website superiortransmission.com/product/superior-stl010/

Odd you are here then

@jaycastillo9313 video popped up in the feed(which is what you want, right?!)...took a brief look, jotted a note.

Until the pill detent fails and ends up inside your transmission yea it works but it’s playing roulette

@zacharycrawfski2276 tje engineering of the part won't allow that

@@everydaydadfixinit4803 seemed pretty poorly manufactured to me in my opinion definitely looks like it could come loose

Yes. I believe others have commented that they have done it this way successfully. I personally have never attempted.

@@jaycastillo9313 Thanks for the reply. Great video btw. Also wondering. Have you ever just removed the tstat block completely and attached lines directly to trans.

@@IS-217 I’m not sure there is a way to do that honestly.

There’s always a risk but it’s slim. More risk of a blockage/restriction than a freezup. I live in Iowa and I have driven my truck when the windchill is -55 degrees and all was good. I’ve never personally had an issue. My truck is equipped with an active shutter which may help reduce the chance of a freeze up condition.

Lube with what

There is no waiting for the valve to open. The actual procedure requires you to get to 194 degrees Fahrenheit to open the valve then check it at operating temp of 115. Now the vavle is gone so just get it to 95-115 degrees (GM recommendation) and pull the 10mm plug (8 speed) until the fluid stops running out and torque or get 95-115 and check dipstick (6 speed)

@@jaycastillo9313 you sir are a great man!!!! Thanks so much. Cheers from central Canada!!! 👍👍👍

@@jaybilawchuk2225 🤙🏽🤙🏽make sure the engine is running when you check the transmission fluid. 6 or 8 speed both.

⁠@@jaycastillo9313 yep. That’s how I do it. All good. I had a check engine light with code PO711 for an transmission temp sensor fault happen yesterday, so I’m scared. lol. I cleared it and have been driving and it hasn’t come on again yet but will see. I have no idea what kind of job that would be to change. lol.

@@jaybilawchuk2225 I did it on my 8 speed! It’s just the temp sensor in the transmission. You just drop the pan. I think exhaust has to be loosened on both sides to get on cover clearance. Then replace the harness, the temp sensor is part of the harness and is not serviceable.

Harder to get the torque wrench in after but definitely doable! Every second helps when it’s your own vehicle though! Not getting paid to work on them, are we? Thanks!!

looks like your a gm tech, me too. 5 years with gm, on my way to WCT

i dont think i ever torqued the thermostat blocks in my life haha SHIP IT@@jaycastillo9313

@@jaycastillo9313 al hacer el bypass tienes que reprogramar la computadora o se queda igual ??

Love to hear that. The vehicles I hate working on the most are my own, I lose money on them!!

@@jaycastillo9313 yeah just do everything he did just kept it bolted to the transmission. Just took alittle hook to get the old spring out. Then put the new stuff in. Very easy

From the Chevrolet parts department at the dealership I work at

Superior Transmission website has it listed “NOW FOR 2016 & up 8L90” so I’d imagine that it would. Procedure would be slightly different but not much.

@@jaycastillo9313 Thank you. I appreciate it.

Yeah, let us know! Wouldn’t hurt to have the cooler flushed . Just to make sure you’re getting good flow. Of all the transmissions we’ve replaced for this issue I’ve only seen 1 require the cooler replaced for no flow. But it’s possible.

@@jaycastillo9313 I’ve replaced the radiator fluid, radiator thermostat, radiator temp sensor, and lower radiator hose recently after buying this truck because the stupid dealership was “kind” enough to drop it off at my doorstep 3 hours away. Long story short when they got to my house there was no coolant due to a leak in the lower hose. Ever since I fixed those things I haven’t had any issues 15k miles. Engine temperatures are still good. AC/Heater works fine. Do you think it’s possible that there’s still lack of coolant flow in the radiator that’s causing my transmission to overheat given all of that information?

Installed and took for a 50 minute test drive. First half of the drive was on the highway 55mph and second half was in city 35-40mph. Still climbed up to 220 but took a lot longer than before. Mechanic claims to have flushed the radiator already. I’ll be picking up a tru cool 40k radiator cooler soon.

they are not related, only thing is they are inside the same case but seperate coolers@@parsingh559

if it still gets hot your cooler is probably plugged, anytime we do converters or trans replacements we flush the cooler@@parsingh559

Nope, not at all. Just make sure to check the level when you’re done. On the 6L you will have a dipstick and you use do not use the fluid in the video. You use Dexron VI .

Awesome thank you. I’m hoping this works so I can avoid all the problems I’ve seen about overheats

@@Chris-hk6np I hope so as well. Good luck!

12650609 (aluminum lines) 23277649 (steel lines)

Awesome, thank you!

Did you learn this through personal experience or did you read about it online? I have the same engine and I just purchased this thing. Don’t tell me it won’t work 😭

@@parsingh559 On any extended trip, it will NOT cool your transmission fluid lower than your radiator temperature with that truck. Without an auxiliary cooler (outside the radiator), the coldest the transmission fluid can get is the radiator temperature, which is about 195F. So if you're looking for something down in the 160F range, it won't do that with that engine. And yes, I observed this because I own the truck that did it. I looked up why and confirmed that with an internet search, it does not have an auxiliary cooler. You can still put it in, and your temps will be lower on short trips as the transmission is warming up, but if you're out for a while, the coolant temp is going to be the bottom limit on transmission fluid temp. To get the full benefit, you have to ADD an auxiliary cooler after the radiator. You can thank GM for cheaping out on this engine.

@@gssmith1986 thanks sir. Have you done anything else to keep it cool? You think regrading the diff will help?

@@gssmith1986 yo what transmission auxiliary cooler did you install? Part numbers would be greatly appreciated. Thanks

You need to take the front grill off the truck and measure the location where it would fit and then pick one of the aftermarket brands. They are dirt cheap and depending on how elaborate you want to get mounting it, pretty easy.@@parsingh559

Have definitely never seen this and I have seen a ton of these things! Will post a part number for the entire assembly just in case. Thanks for your input! We’re all just here trying to save a buck and help each other out 🤙🏽

If you’re using the stl010 just simply hook the flush machine up inline and it will go. on vehicles that don’t have it deleted we disconnect the lines. Start engine, drain 3 quarts into a bucket. Then fill 3. You do this 4 times. On the fifth time you do 4 quarts. This equals 16 quarts. Then I flush the lines and top off fluid as needed. Obviously a lot harder on an 8 speed v a 6 speed.

And I know that sounds very unprofessional but that’s a actual GM procedure 😂. They even sent dealers a bucket will markings on it. They also send two adapters. One for each transmission (6&8) with hoses attached to each.

@@jaycastillo9313 thanks for response man! I plan on using a little hand pump to do this in my garage so I’ll take any advice I can get 😂

@@nolovenoah742 if you’re doing it at home I suggest getting someone to help you just turn the engine on and off. Makes it a lot easier, don’t want to lose too much fluid. If you do it alone, listen for the pump starting to whine. Turn it off as soon as you hear that and that’s about 3 to 4 quarts. Hope this helps!

@@jaycastillo9313 absolutely helps. I’ll have the old lady with me. It may be a stupid question but of course, after I do the bypass- where will the fluid drain from as I do the flush? Still check plug?

Yeah, part numbers change like you change your underwear. You can check again in a year and the one you just put on might charge numbers. You can see parts superseded to a new number many many times over. Doesn’t mean the pet changed, usually just the number.

No problem! Any questions let me know! Be glad to help

@@jaycastillo9313 Yes I like how detail you are in well spoken thank you again

Everyone says it works just as good and it’s free! The STL010 will bypass in the event of a freeze up or blockage in the cooler or lines. That’s the advantage going that route. Hope this helps!

@@jaycastillo9313 thanks for that , next fix is a catch can .

Thank you!

I had previously. So at this stage I just topped off what I had lost.

Will this work for a 2015 silverado?

Same here but a 2016 Sierra Denali. Very easy and used a regular socket wrench.

I was able to use a 3/8 Torque wrench with a short extension over the top of the driveshaft no problem. It fit perfectly between the exhaust and drive-shaft. It was his method and a great how to video. But, I agree. The removal of the drive shaft was unnecessary.

I installed it on mine and made it worse not sure what to do now 😢

@@Pelonskis Worse how? Hotter?

I’m not sure if the part number is the same on the new body style. But I do know they kept the TBV at 194 on the 8 speeds ONLY even the 10 speeds are at 130 degrees now. Definitely something to look into. If it were mine I’d do some research on their website.

I did it on my 2019 (new gen truck). It fits as long as you have the 8 speed.

I think just the pellet (thermostat) inside the housing is the o Lu thing that’s technically updated. So the housing you’re going to buy and the housing you have are probably the exact same. Personally I’d just use the STL010 or the updated thermal bypass. Both just seems like more $$

Yes, I think at this point GM is recommending injector replacement. They say ALL injectors but I’ve been doing the ones that set DTCs.

@@jaycastillo9313 thanks very much for such a quick response, but what’s a DTC ? Thanks

@@duffmeister6480 diagnostic trouble code. Just a code sorry for the confusion.

Hi Jay. My local gmc dealer service wants to replace my wire harness related to the fuel pump pressure sender. Based on TSB 20-NA-197 that recommends changing the connector, it could cause DTC P026D injection quantity too high. And it’s not covered under warranty. The bulletin says 1 hour, they want 2 hours @ $200 plus the part. Shouldn’t they provide visual and technical proof of damage or corrosion to validate this repair ? 2019 Canyon 2.8 Duramax. Thanks very much for your assistance.

Nope. Did them when I bought it. Pushrods where bent as well. Turned off AFM with HP Tuners, haven’t had a problem since.
