Picked up the new ride earlier today.

Thanks for the link to the article. After reading it, no worries with getting the 3.0L AT4.

A few days ago, I've test drove a 2026 AT4 with the 3.0L diesel and was impressed at how quick it moves due to the insane 495 ft-lbs of torque, and hardly heard any engine noise. Earlier today, I traded in my 2020 6.2L TB for it. I pickup my new ride later this week. This is my first diesel powered vehicle and I look forward to the experience of owning one.

Looking at trading in my current ride a 2020 Trailboss with the 6.2L for an 2026 AT4 with the 3.0 Duramax. From what I heard that the 3.0 Duramax is a very good engine. Just wondering from others who have similar trucks with this engine - pro's and con's. Thanks

Yes, that's the option I just decided to go with...keep the truck. I just received the DFM Disabler earlier today. Now I'll need to figure out the oil to use for future oil changes as I just had an oil change done by my dealer (using 0W20) when the recall was announced.

Not a fan of the 2.7L's as the idea of a very small engine in a full-size truck is very unusual to me. However, they do make decent power for an engine of that size. I'd probably go for the 3.0L.

I didn't think much of that option as I figured it would be really expensive to buy a new truck outright with no deposit or trade in. At least if the new breaks down, then you would still have the good-ole T1XX available for use.

My situation is similar as my powertrain warranty expires in a few months, plus I finished paying off my loan last year. So I'm exploring options 1 and 2 and so appear to be leaning towards option 1 as through 5 years of ownership the engine has been solid - no issues.

As a result of the recall issued by GM on the 6.2 in which 2019's thru to early 2021's that were not involved, I'm curious if the options stated below are being considered by these particular group of owners which I'm a part of as I have a 2020. Keep the truck and implement modifications such as a DFM disable/delete and using a different viscosity of oil. Trade in the truck for a new one equipped with a different engine such as the 3.0L or 5.3L, or go for a HD version. Trade in the truck for a new one from another manufacturer.

Hmmm....a little bittersweet for me as I have a 2020 with the 6.2L which surprisingly is not on the recall list. I would have thought they go back to 2019. I have a scheduled oil change tomorrow at my GM dealer so I'll ask if I should be concerned with this recall. I suspect anyone with a 6.2 who is not involved in this recall will want to keep tabs on this development.

This mod I find interesting to do based on the positive feedback. So this DSSV mod on the TB's and AT4's would lower the truck's gross weight and towing capacity ratings due to the softer suspension setup. Thus would it be safe to say that the revised ratings be similar to that for the ZR2 / AT4X?

Installed a Borla Catback Exhaust for the 6.2L. I bought the kit from a local GM dealer.

With lease costs being that high, would it not be better to purchase a new or used vehicle.

Granted the cost of using premium fuel is a bit of a PITA here in Southern Ontario. Comparing the cost of premium (6.2L) vs regular (5.3L) for a typical fill up is roughly a $25-$35 difference which isn't too bad. A full tank for me averages about two weeks as most of my driving is local with some out of town trips. I've been working on reducing my fuel costs by using credit cards that give me a discount at the pump, and doing various upgrades to my truck. I just upgraded to GM Spec Borla Catback Exhaust that so far has increased my fuel range. A cold air intake is next on the list. Now on the extreme side of things I've been getting offers from my local GM dealers to trade this truck for a new 2024, thus if I went that route then I would go for a 3.0L Duramax (ZR2, AT4, or High Country).

Getting back to the topic of this thread, I went from a 2017 Silverado Midnight Edition SLT Crew Cab (5.3L) to a 2020 LT Trail Boss Crew Cab with the 6.2L and the biggest difference to me was the size of the new truck vs the old one....simply put its big! I've attached a picture to show the difference. I had some reservations with the 6.2L but after talking to other owners of these trucks and SUV's equipped with this engine, I came to the same conclusion as them as this is the best engine by far in a GM 1500 series truck and will never go back to the 5.3L. As it stand now, these T1XX trucks are the best ones GM has made so far, curious to see what the next generation of these trucks will be like.
