There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed. International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant. That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways. International also put the plant up for sale some time ago. This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life. The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced. They were manufactured in International's Springfield plant along with the IH MV series initially. When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck. This was before VW bought Navistar out, after that happened no more was said. Draw your own conclusions... About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves. The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has. GM views this as a desirable feature that differentiates their truck from the competition. A gasoline engine option is also expected. As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time. I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers. Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

Fuel mileage? That's all how you use your right foot. Exhaust will give you sound. Stock exhaust 5.3 is 2.75" diameter piping. If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback. I had one on my 2019 old body 5.3 and it was just perfect. Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode. Corsa bumps their catback to 3in diameter.

First brands was the holding company that owned Champion Labs and Fram, + many other auto parts companies. Those brands are not making filters anymore. Premium Guard Inc. (PGI) acquired the intellectual property for both FRAM and Champion Labs. Premium Guard is a similar company as Champion Labs was.

My info is right from stuff we got from GM for the "A" and "B" and what they replace based on the old Duraguard (blue non "R" filters) and Ultraguard Gold (black "UPFXXR" filters) which are now gone as a result of the First Brands issue.

It was this video where I saw there are now 3 different supplier and one of them is a value model.

So far they are all ones "not to stay away from"? I haven't cut any open yet though to compare A and B style. As for what they replace: B = regular "blue" Duraguard A = The "black" Ultraguard Gold. So like UPF63R is now the PF63A. C = That I can tell, alternate supplier or same supplier but alternate model being used. Right now on like PF63 for example though, the "B" is on backorder again so we are using the "A" for both PF63 and UPF63R usage. Same with PF64s, the B is backordered, so we are using A. PF66, the most recent case we got were actually from SAIC-GM from China (GM ETurbo engines so 1.0, 1.2 and 1.3 turbo 3 cylinder). They look like engine assembly plant filters to me which even for US products have different labeling on the cans. These ones are blue with the SAIC-GM logo on them.

I'm still unclear on the multi-supplier A/B/C filter designations, as they all supposedly come from different suppliers now. A = OE, which replaces "blue" AcDelco filters of yesteryear? B = ? C = ? One is supposed to be their value line/ budget friendly. We need to know which ones to stay away from.

The video for the Ford 7.3 tear down is up. He's not a fan of the oil pump design. This one died from the known cam/lifter failure issue. For some reason this site is not letting me embed a link but here it is to copy/paste: https://youtu.be/4Memby-jB9I?si=SmK1VuBgZ7UgsZCz

Thanks everyone and especially Newdude for taking the time to explain the story in detail. I am now much more confident about what I’m ordering.

Thank you for the website reference. It helped a lot, now I can see that there are some other warranties applied to my truck, Thanks again.

Thank you, I took my truck and fortunately it was covered. I am not sure why the guy said it was not. Everything is good, thanks again.

Just was clarifying as a lot has happened in the last 12 years in the filter business Definitely wasn't questioning your impression of the new filters as they are definitely of a better construction it seems vs. the blue ones. We did see a couple of the PF48A's and PF64A/B leak though at the seam where the can and the baseplate mate up. Right out of the box too. So I don't know if it was a bad batch that slipped through or what. 48A would be on like 07-14 LS V8 engines, 64A/B would be like 2018-current Chevy Equinox.

I’m have Magnaflow. Good low note, not loud. However, with aftermarket y pipe and cats, and aftermarket engine, I am surprised you didn’t already do headers. Stock type manifold? That will change the exhaust note a lot to any downstream piece.

Jeeze, get it right next time please!

My '22 had the issue. I fixed it in 10 minutes. Basically involves removing the two bolts holding the plastic assembly around the steering column to access the switch. Take a zip tie and zip tie the switch so it makes contact and doesn't send "shift to park" messages. Replace the trim panels. I actually did my repair in the parking lot of Home Depot, only because I had to pick up a package of zip ties. There are a number of videos on YouTube...

did update day before yesterday, now the push to talk does work to make call, any thoughts

If your Bak Revolver X4S is less than 5 years old, reach out to their customer support team. Email: [email protected] Send them pics of the issue along with the serial number and proof of purchase. As long as it's within warranty they will ship you a new one. I love my Revolver X4S but my shoulders needed something that was easier to open and close. Just "upgraded" to the MX4 EZ-Lift. I'll put a write up together and post it; I'm very happy with it so far.

OK...so I was partially correct. It's not Champion but Premium Guard who is now making the filters for GM. I stand by everything else though.

Anyone who would be willing to help can't because you left off the last 6 of the VIN. Besides that point. You yourself can answer your own question HERE - GM Recall Information | Chevy account | Chevrolet Put your whole VIN in and it will show you all active and expired warranties and coverages.

Correct. Supplier changes because of the First Brands bankruptcy. From First Brands (Fram) to Premium Guard. Champ Labs hasn't "made" filters for almost 12 years. They got bought by Fram in 2014, and then Fram got bought by First Brands in 2019. First Brands no longer makes oil filters as a result of the bankruptcy. Fram fixed and improved the eCore design that Champ made a long time ago that many people didn't care for. So Champ branded filters for the last 12 years are made by Fram using their old design, and then using the new design that was created under Fram. Premium Guard bought the assets from First Brands mid this year. Oil filters, wipers, air and cabin filters, and respective brand names. Premium Guard makes a lot of private label filters including Napa Gold, Carquest, and others. Their main filter supply flow comes from Vietnam Advanced Filtration Inc. Premium Guard Inc.

The blue filters were made by First Brands for AC/DELCO and they went bankrupt. The replacements are now being manufactured by Champion and they are labeled PF63A/PF66A etc. Perfectly fine to use. Interestingly, I just picked up a PF66A for my LM2 Duramax and it is definitely heavier and feels more robust than the blue PF66 ever did. The new one is also painted black. The box had the genuine GM hologram on it, so it's the right one.

i just looked at the N232395310 and it shows your truck is covered, i don't think the vin matters
