Still researching 1/2 tons. I really want the AT4, but the more I read the more I question.

1. Is the 2019-2020 5.3 still prone to weak lifters?

2. Does the ten speed transmissions still have shifting issues like the 8 speed?

3. Most importantly, how bad is the brake issue? Have read that the brakes can go? Thought I read that it might be a computer problem? Have many or any 2020's had problems or has this been resolved?

4. Whats the highest mileage DFM 5.3 (2019-2020)?

5. Does the switch on the dash that releases the tail gate automatically shut while the truck is in motion? I could definitely see me reaching for my 4-ways/flashers and accidentally hitting the tail gate release.

6. No one can still answer if the key fob can be turned off so i can stashed it in the bed without having someone be able to open the doors, start the truck and drive away? posted this before ?

Is anyone could shed light on ANY of these that would be great. thanks

1. I haven't heard if 5.3's having a lifter problem. It's the 6.2 that I've always heard had the lifter issues

 

2. No the 10-speed is amazing

 

3. Mostly I've only seen the brake line monitor counting down to fast. The other things I've seen have all been computer issues. The recall that's out there is for the previous generation

 

4. Do you mean fuel mileage or miles driven?

 

5. If the truck is in gear it won't release the tailgate

 

6. I have not seen any setting that would "turn off" the key fobs. Also, wouldn't you need them active to open the tailgate since it's push button release?

2.  still?  Have you seen a post about shifting issues in the 10speed?  I have not.

6.  I supposed you could remove the battery from the fob and tape it up under the lip of the bed.  Then put the battery back in when you need to use the stashed fob.

I wrap a spare fob in aluminum foil and stash it somewhere outside. has worked in every vehicle with a proximity fob. I haven't seen any options to "turn off" a fob.

Why would you want to stash the whole fob on your truck and not just the second door key...  Another technological invention overcomplicating simple things like a physical key. There are probably apps and stuff for you young pups to unlock your truck by your phone, until your out of the service area like rural Canada. Funny how Ford has had keyless entry since 1995. They must have a hell of a patent on that one...

GM has had key pad access available as an accessory for quite some time.

Because I do alot of whitewater kayaking and rafting, I always (well most kayakers) just hide their keys in/around their vehicle when they are on the water instead of risking losing or ruining a key fob. 

 

Can you start the truck with just the key itself or do you still need the key fob?

 

if you are insinuating that I am young pup,,, THANKS, pushing fifty, more along the lines of "great googly moogly, these young whipper snappers and their new fangled technology,,,,"?

4. Do you mean fuel mileage or miles driven? total miles driven

If there's a 19 with DFM much over 30k miles is be pretty surprised. I mean if that's the case they must live in their truck lol. The DFM engineers are new for 19 so longevity with the DFM is still anyone's guess...

Why wrap it in foil? For less than $7 you can get an RF blocker pouch you can use on a cell phone or to block signals from a keyfob; Glue attach or hide it in a storage location and it is shielded from the weather and can rapidly be accessed.

I do a lot of bank fishing and don't like carrying my keys with me in case I'm a bonehead and somehow inadvertently pull them out of my pocket and drop them somewhere along the bank. On my previous trucks I'd just throw the keys up under the rubber bed mat and leave it at that but with the 2019's FOB I was worried like you if leaving it in the bed would be a problem. I started placing them in the gas door area and found that in order to activate the buttons on the door handles to unlock the truck you had to have the FOB in hand. Not sure if its a motion thing but it seems that the truck may be able to sense if the FOB has been in motion (proximity sensor?) before it will allow an unlock. In any case I picked up a 3M hook at Lowes and stuck it in the top of the gas door well for simplicity and now just hang them on the hook.

Because for less than .02, I can use foil and it’s a just as effective faraday cage. And it works. Plus it’s readily available. 
 

 

to be a little more clear, I generally remove the little metal door key from whatever fob, hid the metal key in a magnetic hide-a-key on the outside. Then stash the foil-wrapped  fob in the cab. It works.

I have a custom so I do not have the keyless entry, but my wife's grand cherokee does.  Not sure if the GM vehicles are the same, but her mirror lights will flash when you are close enough to unlock.  Only noticed because I was washing it with the fob in my pocket and the lights kept flashing.  If GMs do this, it could give you an indication of where you could hide it.

      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.
