2016 Transmission Issues

I have a 2016 Suburban LTZ with just shy of 100k miles on it.  I bought it used with 40k miles on it.  I've never towed anything heavier than a riding lawn mower, but I'm having transmission issues.  The last couple of months it has been shifting hard, especially in low gears.  When I use manual shift I can control it just fine with no hard shifting problems.  Dealer told me I either need to replace the torque converter ($1,500 with labor) or rebuild the transmission ($4,500 with labor).  I chose to reset the ECM and replace the fluid instead, but that didn't solve my problem.  Has anyone else had this problem?  I don't want to spend $1,500 on the torque converter if that isn't going to solve my problem, and I don't want to rebuild the transmission if all I need is a new torque converter.  

 

Side question--a friend told me if the transmission is toast, the engine isn't far behind.  Thoughts on that?

I just bought a 2015 LTZ that well cared for and I got a bumper to bumper for 3 yr/ 36k and it had 97k on the odometer. I would suggest getting a extended warranty for it! If it was the Torque converter you would be getting codes. Get another opinion. I think Chevy has 0% offerings for the extended warranty as well. The LTZ has tons of electronic stuff so if you're going to keep it you should get the warranty or trade it in as soon as possible, just my 2 cents FWIW.

Nope.  I think it was 60k miles.  

You are correct.  5 years/60,000 miles for the powertrain warranty.  The rest of the factory warranties apply as follows:

 

Bumper to bumper is 3 years/36,000 miles.

Corrosion protection 3 years/36,000 miles.

 

Rust-through protection 6 years/100,000 miles.

It's a common problem with this transmissions on Suburbans and Tahoe, I had a fleet of 5 Suburbans and replaced transmissions on all of them at various mileage (as early as 50K miles but also had one failing at 185K miles) So it all comes to luck in the end...

      Wow I'm in a pickle. (Broke down truck) and a story.

      I have an old dental chair in my shop. Something I got for free and apparently it has more than scrap value? People collect them although mine isn't restored or anything. It's visually interesting (1930's Ritter) which is why I like it. And it IS decently comfortable if you kick back.   When a good buddy of mine saw it he said, let me guess, Atlas. It's a conversation piece? As in, you ask the questions, they do the talking?   Where do you hide the jar of teeth?   I would never.

      OCI, not when but why?

      Are we talking about the same thing, though? The 7 versus 3 wear metals was from Lakespeed's 3.0-specific oil brand comparison test between AcDelco oil and Mobil ESP. The filter remains a constant so whatever excess particles the AcDelco oil is producing aren't being filtered out.   I'm assuming there's a parallel comparison to be made; IF the filter can filter down those particles, engine life increases, and your graph makes the case that a better filter (lower micron rating) can increase engine life. Introducing fewer particles AND filtering those particles with higher efficiency is the best of all worlds. Good oil, good filter.   Where we may disagree is the "baseline relative engine life". I'm more apt to believe the base engine life value is 200k+ on very average oil and filters, "bulk oil of unknown brand and white-label generic fleet-grade filter, Jiffy Lube"   Going from a 10 micron filter to a 5 micron filter should boost a base 200k to 275k in a vacuum as a single factor alone.   Here's the whatabout: How does regularly changing the oil and filter ahead of recommended schedule influence baseline engine life? Most people aren't going to science the heck out of this stuff or ask about Micron ratings, HTHS, or wear comparison tests at Jiffy Lube. Most of the Jiffy lube techs would say they need to call their tech support line to even try to get an answer.   --   Because we love anecdotes here, when I was fishing for 4.3 parts at a local yard this weekend, ALL of the 4.3 vehicles had well over 200k. I love looking at odometers of junked vehicles. How far did THIS go before landing at the crusher? The ones that still had engines weren't seized. None of them were vehicles I'd consider were Amsoil queens, in fact most of them had some kind of service cling-sticker in the corner of the windshield indicating it probably had very average maintenance services. Even the fresh parts rigs- I'm not sure taking an S/T series to 400k has much value considering the running value of those vehicles was probably somewhere around $1,000. 25+ years is a good run on time alone.   The intake manifold I salvaged had clean and bright pool areas. As expected, I found the fuel lines in the manifold rubbed through, just like mine. I'm guessing the lines on that donor truck started leaking, the truck started running rough, and its owner said that's enough I'm unwilling or can't take it out of service for several days, or spend $1000+ to repair it at a shop, it's simply time for a newer more reliable vehicle (or, more than likely, this is the 2nd, 3rd time this has happened in the truck's lifetime). While I don't count on my Blazer for reliability, the thought of giving it away for parts at certain points during my adventure, and being mentally free from its needs has has crossed my mind. I'd be losing $1500 or so, but I can only make more money; not time.
