I have a 2017 GMC Sierra 5.3 with the 6L80E. Needless to say my transmission is shot on it already. Unfortunately I am out of warranty so all cost will be coming out of pocket. I’ve shopped around locally and all shops range from $3,000-$7,200 to rebuild mine.(Tucson,Arizona) so I started looking for some remanufactured transmissions online. I would like some opinions and some sites you have used before. Street smart transmissions/ Best Buy Transmissions/ GM factory remanufactured.

Did you buy the truck new? Go to the dealership and ask them to see if GM can give you a discount on the price for being a loyal customer.

I had not thought about that. I was planning on going tomorrow as today is Labor Day and everything was closed but I will for sure try tomorrow thanks.

I have a 2017 Silverado with 142k and am shopping for transmissions. Mine is still drives, but exhibits the rumble strip vibrations randomly and the general clunky shifting has gotten worse.  I got a quote from a local (Rochester, NY) Chevy dealer today. They quoted $4875.00+tax for a GM replacement transmission. It comes with a 36 month, 100k warranty. Two day turnaround.

 

Not really to bad, but these things should go more than 140k before falling apart.

 

Two buddies with 2016 Silverado's both had transmissions go right around 125k. They used a local garage and found rebuilt transmissions on-line. They spent almost 4k.

 

Has anyone got over 150k on one of these 6-speeds?

You've done the trans flush with the new fluid right?

I was @ 122,000 and my 2015 6L80 trans went out and the dealer I bought it from, used, got Gm to pay $2000 on the replacement.  Same warrenty as above. It now has another 92,000 and it’s been fine. I did get it reprogrammed shortly after replacement. 
 

 I would def go ask the dealer.

Just saw one on Precision Transmission's youtube video with 154K and the fluid was brown.

 

The reason these things don't last in your K2s is because of the transmission thermostat.  "Flip the Pill" and they will last 2 to 3 times as long like the older 900s.  We've seen them go 300-400K miles.  Change the fluid every 40K miles  or so.

Dealer warranty is the best. Others are 1 year 12 k I think.

I went Dealer for my 93. Installed myself. No affect on the warranty back then. 

Ask questions how they rebuild the trans. Most just do clutches, seals. I was told GM remans get all parts that don't meet spec replaced.

Maybe dumb question here. What do you mean by flip the pill?

I'm right at 150K and works like a dream. Cadillac Luke is close to 200K on his. So yes....

Trans has a thermostat. It has a pill under the plug. Flipping over bypasses the thermostat so it is on the trans cooler all the time just like every transmission built before 2014. Here's another option many like that does the same thing but with a pressure relief. The pill flip it free however. Well it cost you some time. 😉 You tubes on the flip posted dozens of times on this site.

I got 167K on mine.  Bought it with used 101k miles on it bone stock 6.2 L86.  Heads, cam and full bolt-ons done by 125K.  Big tires and burnout and she is still doing good.  Doesn't mean it won't let go tomorrow.  But for now I sleep good at night.

That's the kind of mileage we should all expect from one of these transmissions!

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
