The GM part # is 84016022. I purchased this just after buying the Silverado in 16. I'ts not cheap by any means at $432.15 although it's the only CAI that will not have the Service Manager questioning you if you have a motor or ECM issue. It also doesn't need any special programming although I'm sure it could benefit from a tune. There is a GM sticker that comes with the kit that is legal in all 50 states plus has a C.A.R.B. #. I can say that it gives me around 2mpg better in the city and about the same on the road. The other thing that surprised me was under full throttle from a stop when it hits second gear it does chirp the tires...which it would do before I installed it. I bought mine from Suburban Chevrolet, "www.trunkmonkeyparts.com".

Perhaps this is what GM wants, to be like mopar. Create parts that should have been stock on the truck, and charge twice the price and profit more. 

 

Either way its it’s kind of disappointing to see no real substantial change on the powertrain figures. But then again, if the 5.3 is doing great in terms of durability and performance, there’s no need to change it. My guess is GM is trying to really nail the MPG area to be competitive with Ford.

1. Yep, that how upselling works.

 

Point 2; They don't have to do much as none of the Ford engines appear to be able to meet what the GM engines can do mileage wise in the real world. I see lot's of guys post their numbers on Facebook truck groups & all the ecoboost engines are getting much worse than I do with my 5.3.

I don't so much care about the HP ratings.  They seem fine.  I'm much more curious about the MPG especially with the 10spd.  I'm a little disappointed to find out the 10spd won't be paired with the 5.3 especially in the Boss Trim.

What??? It doesn't even replace the intake tube which is a key component to intake upgrades. Might want to hit up GM and let them know they just need an intake to gain 2mpg, could be well worth their time and sales advertising 2mpg better from just an intake... Maybe you can get a cut of the profits as I am sure that will drive sales!

With nearly a 500lb diet and two more gears I bet the reduction in 6.2L torque will be noticeable and was probably done to boost MPG. Also possible that the torque reduction was necessity to keep the 10speed within it operating limits when towing heavy loads.

500 lbs is nothing.  insignificant.  Maybe good for 1/4 of a MPG fuel economy.  If even that.

Everything I have read out there says 100lbs is generally good for about 1% in MPG give or take as a rule of thumb. So 500 lbs on a 5500 lbs truck is 11% in weight loss, not exactly "insignificant". Going by the rule of thumb noted above if the current truck gets 23 mpg then a 500 lbs saving can get it just over 1mpg back, or lets just say a round 24 mpg or 1mpg. That is just in weight, then you have aerodynamic savings from reduced drag that could be off set some by larger tires/wheels, ect. Either way 500 lbs isn't insignificant at all. In drag racing the rule of thumb is 100lbs equals roughly 1/10th in the 1/4 mile, so 500 lbs is again not insignificant but can be off set by taller tires, more unsprung weight, ect. Either way, it is pretty big and will have an impact (not to mention helping tow ratings and reducing wear and tear)...

Sorry to get back weeks later although I thought I show the "new" intake tube.

      primary drive belt tensioner

      By Deadwood · Posted

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      By swathdiver · Posted

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
