So I had a converter built for my old Dodge, and got talking 6L90e because I was driving my truck. 

 

He asked how many transmissions I've had done, and I'm like none?  He asked how many miles, and I told him 230k.  He told me I was an all time record for miles on a 6l90e that he has ever heard, most didn’t make 100k...told me the converters usually burn up which takes out the trans.  He did tell me my frequent fluid/filter changes probably help (I also have an extra cooler).

 

So what is the life expectation of a 6l90e?

Hard to say really but I've seen plenty at that 200k+ miles.

 

In fact I just tuned a 2011 truck with a 6L80 with 202k with the original transmission still. He wanted it tuned, so I did it even with that mileage in hopes of getting more life from it.

 

My work has had 2 big box trucks that made it over 150k on the stock transmission and those truck were always loaded to 10,000lbs easy every day. So I'd say if you get 200k on any stock transmission, you got your moneys worth on these trucks. Different trucks with a diesel that run an eaton, allison or heavy duty like that should see way more miles.

181K on mine. Shifts great. I run it colder and do frequent fluid changes. I'm happy. Shifts nicer than any of my TH-350's or TH700-R's. About the same as the 4T65E in the Buick.

ZERO problems with mine either (2012 GMC 2500), and I've been hauling a 3,200 lb camper all over Alaska, Canada, and the entire western US.

Tin foil hat time.

 

6L80/90 from 2007-2013 and 6L90 on 2014 HD seem to last pretty good.  Something changed starting 2014 6L80 and 2015 6L90 which my guess is post-bankruptcy blues and there were some changes or cost cuts made to components on these.  We almost never did 6L80/90 internal work on those older ones, but the newer ones even into 2020 trucks?  Plenty of them have been opened up.

Interesting, maybe he was making a blanket statement for all of them when he was thinking just newer ones?

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.

      Needing this part.

      I'm sure if you went to a junkyard where you go in and pull the part off the truck yourself, not a used part place where they do it for you, you can get that part on it's own.  Depending on if and what else you would be buying, and time of day, they might even just skip over adding it as a item to the bill.
