Here is the part number off the GM site. Contact a local dealer to see if they can get you one.

Otherwise you could contact a torque converter company and see if they can match you up with a converter that is just like the stock 6L90e. Summit racing, JEGS, Circle D converters may all have what you want.

Yes you can replace the junk 6L80e converter with a better stronger 6L90e converter. I did this yesterday 11/27/2021 on my 2017 Silverado 1500 2wd with 78k miles on it. It took a buddy and I about 6 hours to do it. I developed a shutter and bucking so I ordered the 6L90e converter, a gasket/seal kit and got the trans fluid. we dropped the transmission out, pulled the transmission apart because the 6L80e converter ****** it’s guts out into the trans, metal shavings everywhere so we just wanted to flush it and make sure everything was ok which thankfully it was. The 6L90e converter is a little bigger In physical size and it has 6 bolt holes but you will still only use 3 bolts to the flywheel unless you spend the money and extra time to replace the flywheel as well which isn’t needed unless you are adding lots of HP as well with other mods.

I only have about 150 miles with the new converter but it seems better and the shifts feel better then they ever have.

I’m in California my converter came from Reno Nevada I had it in 2 days and my local trans shop had the gasket/seal kit and fluid in stock.

I believe new, honesty not sure my buddy works at the dealer and he ordered it in for me. I did pay a $100 core charge and am unfortunately not able to get the money back for core because my core isnt the same as the one I purchased if that makes sense. Which I knew that when I ordered it.  But from my understanding that is normal anywhere you buy one from.

i think the oe 6l80 converter is fine , as long as you reprogram the tcc functions in the tcm.  GM meeting MPG  goals and emmissions ratings is almost a death sentence before you get 100K miles on a 6l80

I had one in mine for a short time.  It didn't give me any performance gaines at all.  It's felt like a stock 6l80 converter and even when I tried to stall it up on the brake it didn't seem to stall any higher.  I don't have any logs to prove that it didn't simply because I don't 4x4 lunch my truck alot.

 

When my trans went out I just let them put in a similar stock stall converter that they had in stock and would warranty.  Mine went out last year and parts where hard to get and I need my truck back fast.

 

But yes it does work.  You just use three of the 6 holes to bolt it up.

      There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.

      Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By xdieselmechanic · Posted

      Forgot to mention that this started after changing the oil I use mobile 1 full syn with mobile one filter but I did add pro lube additive and was the first time doing so and is making me wonder just can't see why that would matter

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By xdieselmechanic · Posted

      I apologize for long post put going to try to explain everything. Parts replaced so far: Cam sensor Crank sensor Cam phaser valve Cam phaser solenoid Fuel pump Maf 1 injector Pcm Pdm   So about 2 weeks ago coming off the highway my 2007 yukon xl with the 6.2 stalled and would restart. Had unit towed back to house and I messed around with relays and unit started. Drove it the next day and same thing. Had it towed again. Scanned unit and had code p0300 with misfire data showing mainly cylinder 7 but I know that won't cause a no start. Measure fuel pressure and found only 42 psi replaced pump to have unit stall again and not restart. This time I stayed on back roads and just waited for it to restart about 30 to 60 min. During this time I found I have no injector pulse but have good power at injectors. Started unplugging 1 injector at a time and found when unplugging cylinder 7 pulse came back so i changed injecto and same issue. Turns out unit just happen to ready to start at that time. Scanned into unit and found no reason for the pcm to take away injector pulse so I replaced the pcm and same issue. I figured timing sesnor controlled the injector pulse so I replaced both sensors and while I had the water pump of i replaced the vvt components while i was in there. Read multiple people have luck chaging the maf for this issue so I changed it. Unit still stalls to this day and loses injector pulse on the ground side when it does. Have noticed watching the live data the pcm is request injectors to fire via injector pwm value. I have redone the ground wires at the left bottom of the block knowing this was the ground location for the pcm but still no luck. I am a mechanic by trade but this is having me pull my hair out. If anyone has something to have me check I will gladly im not much of a parts thrower but im about to load the cannon

      auto mechanical driver's door unlock without pressing button? [2026 Silv. 1500 WT 4WD RC SB 2.7L]

      By newdude · Posted

      Actually.  Wait.   I just re-read your original post.  Are you talking from INSIDE the truck you have to hit unlock?  Or from the key fob?  I had assumed from the key fob.   IF you are talking the inside unlock button, I assume you are shifting to park and its not unlocking the doors?  If so, that is changed via the settings page in the radio.  Go to SETTINGS, then VEHICLE and then it should be under LOCKS or DOOR LOCKS or something like that.
