Agreed.  There is planned obsolescence in every mass produced, manufactured item.  GM is just telling you the parameters they shoot for in the design so that it will last long enough to where they don't have to cover it under warranty. :)

 

And how long is that warranty? 

5 years or 60K miles!

About how long people finance, right?

Mine with the 6.2 stays around 130° to 148°

If I am not mistaken, 185 F is the operating temperature of the transmission.  For those of you below 150, I wonder if your transmission has had time to fully come up to operating temperature.  Mine w

You guys talk like these trucks dont last lol.  Ive seen a few with 200k+ miles on this gen's platform at work.  With how many sell, you are going to see a good amount of issues arise, and with todays world, word gets around a lot quicker than in past times so it sounds a lot worst than it realistically is.

Couldn't help myself.

 

Failures as you say are less common than successes. If not GM would be out of business, right?

 

That said failures occur and most failures are self inflicted. Not that the set up isn't already there but really?

 

If a part is going to fail because of heat treat, dimensional or design issue, that happens pretty darn quick. Last round of lifters failures happened between 500 and 5000 miles. Heat treat. Now blow out of proportion. If you have a failure past say 20K then you have a maintenance or other related issue, like lubrication. More common that you think.

 

Forum like this???? Yes...only the failures come here...NOT. And we try to let others know what has worked and what has failed in prevention. Problem is???? Yea... There is that and this ain't that. No false flags here sir.

So, my 130 degrees range, is after an hour drive up to the Adirondack mountains, overall about 1200 feet of increase in elevation, some hills, some flat spots.  Still stays at 130.  2020 AT4, 5.3 with 10 speed.  Towing my sled trailer, on same trip, maybe 140s.  My old 2014, with the 6 speed, I could fry an egg on it, mainly because of the thermostat in it, 195-210 all day long.....

Sorry to be clueless, but how do you tell the temp of your trans?  Is that something that comes standard that I’m just not aware of, or does that only come with certain options of towing package.

Lot's of WE and ALLOW.

And how did that work out for their customers? 

 

Investor owned and driven companies such as GM are all about $$.  Engineers may set the spec's but the bean counters are required to seek out the lowest prices on parts and services.  And like almost everything made by a low bidder, short cuts are taken and lower quality additives are used to meet the low price of the bid.  

 

The goal it to make it last the warranty period, after that its the customers problem.

You can check your transmission temperature by navigating through your digital screen on your instrument cluster via your steering wheels controls.  If you don't have that option, you can check your actual transmission temp gauge on your instrument cluster.

Thanks. Found it.  Running at about 130.

Im curious if you guys with low temps are just cruising at low rpm's. Soon as i start actually driving and keeping high rpm's my tranny temp sits around 180-215 depending and fluctuates up and down, but normal cruising it maxed 178-180.

Its not necessarily a matter of low rpm so much as load.  Going 50 mph at 2,000 rpms is much easier on a transmission than 70 mph at 2,000 rpms due to kinetic forces, or loads, such as wind.  The load on the transmission is significantly greater at higher speeds and during periods acceleration, and internal heat builds up accordingly through friction forces applied through the  transmission's torque converter, clutches, brakes, etc .  My guess would be that most of the low temperature reads are from individuals with short duration trips or a lot of low speed, ie low load, driving.  Stay long enough on the highway at cruising speeds, and the temperatures will get to the 180-185 F range.  Put-put around town for 30 minutes and the temperature may never reach the 180 F threshold, again a matter of load, not necessarily RPM.

There are at least 3 methods on a the Denali.

 

if you can put it in tow/haul and the voltmeter (right hand one of the 4 gauges at top of display) switches to transmission temp. 

It can be switched in/out of tow/haul anytime for a quick temp check.

 

In the trailering app, it has a page that will display trans temperature. 

On '21's, the trailering app is standard on '21 SLT, AT4 and Denali and is available on SLE and Elevation

I’d be curious to know if those who are in the hotter side are lifted trucks and/or with oversized tires.  I definitely had an increase after a lift and 35’s.

Lifted trucks, or rather trucks with larger and heavier wheel and tire combinations, should generate more heat within the transmission resulting in shorter times to reach operating temperatures.  The increased rotational mass combined with an elevated drive height inhibits acceleration, increases wind load, and in turn will increase heat through frictional forces within the transmission as it tries to maintain the desired results of your right foot's input.

 

I personally don't mind though, its worth it :)

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
