I am at 3169 miles and only drove about 320 of those with AFM activated, of those 320 miles it was in V4 mode for maybe 20 miles max. First oil change was right at 2K miles and if it matters I run a RXP dual can setup. Not sure where the VLOM filter is but guess I better find out! The Range works great...felt weird putting it in Drive, not L and hitting the button until I got to L7...went to dinner and it worked perfectly!

Hey, did not know you were buying a Range, could have sold you mine that set off CEL's in my 14 on a weekly basis. Not to rain on your parade, actually snowing in Seattle right now, but you will not be able to get any notices from OnStar, or be able to do  anything else with your OBD II port. Probably not a big deal, but I found out after the fact.

I haven’t gotten 1 thing from OnStar. I hit the button on day 1 to ask them to turn off the Infotainment demo mode...never heard from them again. I did a lot of reading and the earlier Range units had some problems but after several inputs from members currently using them I went ahead and ordered one. If I need the port for some reason I’ll pull it out and put it back when done.

When it worked it was great, not sure about current versions, but first runs also has a bad habit of draining battery over the course of a couple of days if you did not start/drive your truck. I thought the best part was the cool blue/white glow that the lights emit, kind of like driving in an X-Files episode, without the abduction or probing part....

According to them (tech support) they fixed the battery issue too. All version 8 and above no longer drain the battery. They do recommend if you’re storing your vehicle to remove it because it does pull a tiny draw on the battery, I was told the older units used to keep a module “awake” and that module kept others active. We will see...got my tax money back so I just did it, wasn’t expecting a return from IRS. I have the Alien green glow..

Order of my upgrades):

  1. K&N filter swap (day 1)
  2. Flowmaster Force II stainless cat-back dual exhaust with Super 50 muffler (no flapper)
  3. Range AFM Disabler - Removed (trouble codes, no start, battery drain and having to remember to remove it)
  4. SCT X4 tuner - discovered it didn't have AFM disable without more $$$ for a custom tune.  No 5.3L tune.  Windows install issues.  Returned for refund
  5. Diablosport Intune i3 tuner disabled the V4 mode.

 

NOTE:  I have the original single exhaust and a fresh Borla muffler in the garage attic if I decide to chuck it all and return close to stock.

I love the sound of flowmaster but have swapped out way too many do to rust.  Borla is the way to go.  And pay diablew.com to send you a custom tune for that i3.  Its $150 and you wont even recognize the truck when you upload it.

My Flowmaster system is 409 stainless.  Not as rust resistant as 304 but more resistant than aluminized steel.

That's exactly why it'll rust.  409 is barely a step above aluminized steel.  409 is prone to rust especially in colder states where salt is used.  I replaced 3 rusted out flowmasters (one aluminized and two 409 ss) before I finally gave up.  If you don't live in a colder state you're probably ok.  If you do It'll be rusted out within 5 years.  Borla and Magnaflow both use 304 ss.  They're also flow thru design, which IMO sounds a bit better than baffled. Just my 2 cents.  But if you do find yourself replacing that Flowmaster I'd take advantage of that Borla in your attic.  Like I said above I was a bit disappointed at first, but now that its broke in it sounds awesome.

When I did mine I was looking only for sound. That V8 needed a wake up! Anyway I just replaced the muffler with a Flowmaster 50 Series, clamped the flapper open and using the Range.

      What have you done to your K2 today?

      By mysery1 · Posted

      I have a 2018 Silverado Custom with 156k on the odometer. In the last month I've replaced the plugs, wires and the driver side engine mount. My wife just returned from a trip of about 1500 miles and told me the brakes are making a grinding noise when applied. I drove it and looked it over and this is what I found with the driver's side rear rotor.   I'm going to order new pads and check about having the rotor resurfaced. Hopefully this is easier than the last 2 jobs.   Peace

      5.3 / 6.2 valve covers / oil burning

      By FiLo · Posted

      Any update if the new valve cover help with the oil consumption?  I have a 2014 GMC sierra and my truck is consuming a lot of oil so I’m wondering if replacing the driver side valve cover will stop some of the oil consumption. Thanks

      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.
