After owning both 2015 Chevy 2500HD 6.6L and what I own now, a 2020 GMC 1500 AT4, both ? law, its hard to pull the trigger on a new 2021 GMC 3500 AT4. Were currently looking at Ram Laramie 3500 but not have yet decided. How has your experience been with the new GMC HD AT4's? Would like your opinions. Thank you in advance.

They have their issues for sure.  So do the Rams and Power Strokes.  No guarantees :(

Thanks. I can deal with little things but when it comes to safety for my family, then I have a problem. I'm getting the same feedback on Ram forum as well.

 2020 2500 AT4 Duramax with 7600 miles and no problems thus far. I love this truck and would probably buy it again, but man I love the interior of the Ram's with the huge Tesla-like infotainment system.  Wish GM would redo their interior, my 2020 interior doesn't look much different from my 2014.

gSwift, thanks for your input. The Ram has nice interior but lacks the transmission update. They need a Allison transmission. But the Ram does have some problems with the 12' screen but I don't mind the little things.

Just an FYI, the 2020+ HDs have an Allison-branded 10-speed transmission. The trans is built by GM and Allison licenses their name, unlike the old 5&6-speed Allison 1000 series trans in the 2001-2019 trucks that was actually built by Allison.

i've had both. 2018 Ram 3500 with Aisin. Not a single problem with it in the  1 1/2 yrs I had it. My brother-in-law bought it. 

Now in a 2020 Sierra 3500. It does have some of the little issues talked about here. Time will tell

 

The Ram felt more solid. The GM is more fun and comforting to drive.

Both haul my boat just fine.

 

If you go with the Ram, make sure you get the Aisin transmission. I have had 2 trucks with it, never a problem

Thank you for your input. It might just come down to who ever is giving the better deal. If I go Ram I'll stick to the Aisin.

You might want to forget the trucks all together and weigh everything else too?  Dealership?  Distance too?  Warranty? Expected Maintenance costs?  Let's face either MFG could give you a problem child then add in the Dealership?  Ouch...Now your one pissed off dude!

Two things influenced my decision between a new Ram and the GM: 

 

First was price. At the time I bought (summer), Ram dealers had little to no inventory and wouldn't deal. The best I could get was about $4K to $5K off MSRP including incentives (which were paltry at the time). Since I qualified for Family First GM discount, I was able to get over $10K off MSRP with incentives.

 

Second was the CP4.2 fuel pump in the Ram. There were already reports of failures (though not widespread) in the 19-20 model years where this pump is used. There are folks saying that the mid-year 21 models have gone back to the CP3.

 

As a bonus, the Allison/GM transmission in my Chevy shifts like butter and tows like a dream. The Aisin has a great reputation for reliability and towing but many owners report clunky shifting when unloaded. Either would have been a nice upgrade from the 48RE transmission I had in my previous truck - 2004.5 Ram 3500.

 

As far as problems, I had a couple of leaks fixed (one oil and one DEF) and there's a buzz in the dash when the truck is cold. It goes away after about a minute of driving. It's a known issue that I'll have corrected at my next service.

Njmurvin, thanks for you input. I've had a 2015 LTZ 2500HD with the Allison and I hear you, its awesome. I think if they were to install them into the Ram it would be a done deal. I didn't know Ram was having a pump issue, that's no bueno. Trying to stay out of the shop for awhile saves me time and money. Pretty good to hear you were able to get 10k off MSRP. I usually let my wife do the talking. I think the prices are good now but unfortunately I'm not buying till Feb Mar timeframe.

Yes.  The CP4 is why I avoided considering the Dodge when I was looking for a replacement for my 08 Duramax.  When I heard that GM did away with the CP4 for the 2017 and up models that's when I started looking hard at the GM trucks again and found a great deal on a 2018 this year.  (well good deal for this year, all the new and used prices shot up big time thanks to COVID closing plants and reducing new inventories.  I believe Ford has eliminated the CP4 as well, but the 2011-2016 Duramax had the CP4.  I had a 2012 Duramax for about a year that had all sorts of DEF and DPF issues (all covered under warranty) but was fed up with that and got rid of it once the warranty expired and the glow plugs started going out and NoX sensors as well.

I was very close to buying a new Ram. They’re a beautiful truck. Unfortunately there is no room in them if you’re tall, my right knee was against the dashboard and my head was brushing the headliner, with the seat all the way down/back. I couldn’t believe it. I was ready to buy it as I was really smitten with the truck but that was a deal breaker for me.

 

I then drove the new GMC and despite finding it a little visually unappealing, I really liked how it drove compared to the Ram. The Ram felt really stiff and the engine felt laggy in comparison. So much more leg, head and shoulder room in both the front and rear seats. Only complaints are the spongy feeling brakes and the kind of awkward looks. I like the interior, it may look a little underwhelming but everything is well laid out and pleasant to use.

 

One more thing the Ram really lacks is bed access. GM’s bumper steps really are great. Better than Ford’s tailgate step, and Ram still has nothing. As for the Multipro tailgate, I could not care less about it. I have it but don’t need it or use it.

I agree about the room. I'm not tall, but I appreciate the rear leg room in my new truck (especially compared to the smaller quad cab in my old 2004.5 Ram). My neighbor has a 2019 Ram 2500 Mega Cab. It has an elongated cab, but they put the extra space behind the rear seat for storage instead of expanding the leg room. It seems like a missed opportunity to me.

      2012 Sierra 1500 AC issues

      By newdude · Posted

      Needs a manifold gauge hooked up and the pressures read.   If you don't have one, time to take it to a shop and have it diagnosed.

      2018 Sierra 1500 Transfer Case Leak

      By newdude · Posted

      How rusty is the truck?     The transfer cases on these are an aluminum case.  If its anything like the rear diffs on the 2015-2022 Chevy Trax, those will corrode bad to the point it will push fluid through the housing via corrosion porosity or a crack from age/stress.    We have seen folks over tighten the drain and fill plugs on these transfer cases and crack them that way as well.    So I'd say its a 50/50 shot on re-sealing the case.  If all of the surfaces are good and its not badly corroded, they probably can re-seal it.  GM uses RTV to seal the case halves.   If they mention JB Weld, the issue is the case.  Be it a crack or corrosion.  JB Weld "might" hold if they clean EVERYTHING very well and drain the fluid out of the case and clean the crack and then seal it.

      2018 Sierra 1500 Transfer Case Leak

      By Ryanwehr14 · Posted

      A while back, my truck (2018 GMC Sierra 1500 5.3) went in for an o2 sensor and routine service. The tech identified that my rear output seal on my transfer case was leaking, and recommended I have them replace it. At the time I didn't think anything of it, and had them do the repair. Less than a month later, I noticed that the recently repaired seal was leaking again. I called the shop that did the repair and they warrantied the repair and replaced the same seal again. A few months later, I noticed that once again the same seal leak had come back. It wasn't a great time to bring it in and I ended up just living with it for 6 months or so, noticing small (smaller than a baseball) size oil stains below the truck when it would sit for a while, as well as oil spray on the frame (to the point where it actually took the underbody coating off in that one spot). Finally got around to brining it in again, but this time I took it to a dealership service center since I am in a different part of the state for school. They identified the same output seal leaks and recommended they replace them. They also said there was no scoring on the inside of the transfer case, so it didn't need to be replaced. They chalked up the original repair failures to non oem seals and a job that wasn't done correctly. Now they called and said the seals are holding after driving/sitting for a while, but they found a very small leak in the middle, that they recommended they seal with some kind of silicone/jb weld (not sure what they are using). I haven't picked up the truck yet, but I have been reluctant about this whole repair process because I feel like they are just fixing the same thing that keeps coming back, and I am concerned there could be another root cause for the seal failing. Has anybody else experienced anything like this, or have any ideas on other things that could be the root cause?

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Unless you are using a bypass filer system with a Beta of 1000 at 2 micron the commercial filters we have access to, even the very best of them, are poor at the 5 to 10 micron range the typical UOA test can 'see'. Point is there are some truly awful filters being sold A 45 micron Beta 75 filter is what Dyson used to call a screen door on a submarine. That leaves wear metals disconnected from filtration unless particulates are larger than the test can 'see' and yet captured by the filter...which is its job. If that is true then you have a major issue screaming at you.    The graph isn't mine. It belongs to GM and their study on this area. I looked up those studies and provided those SAE tech paper addresses multiple times. Machinery Lubrication displayed it and confirmed it. So if you have doubts about the study you'll have to take it up with GM Engineering. Just like you would have to take up a difference in opinion about the meaning a word with Webster or the length of on inch with the National Institute of Standards and Technology.      Most manuals have two schedules. "Normal Service" and "Severe Service". On it's face it tells you that oil in severe service is more highly stressed and doesn't "Last as Long". The item to bore in on is LAST...what does that mean?    It's the same question one asks about how long to toast bread. What are the inputs? Bread type? Wattage of the toaster? Distance from the elements? What is your preferred level of done?    So lets paint this with a broader brush. Oil is made up of the base and the additive package. The first is altered by heat and oxygen and later is sacrificial with a finite life subject to inputs toward that end. Resistance and supply.    It is the reason an OEM's OCI's are determined by 1.) the specifications of the recommended lubricant and 2.) risk management toward the bottom line. Those lubricants are also subject to cost effectiveness for the OEM.    There is a tendency for most people to believe that the OEM recommended oil rest on the top shelf and that anything other is lesser than. Truth is there are more oils on higher shelves than those on the lower shelf below the OEM's. They make that choice on COST TO THE OEM. Testing is incidental to the margin.    GM makes MONEY, the car/truck is a TOOL to leverage MONEY. Insert whatever car brand you like. Until you forking over a million plus COST not quality is the driver. Thus it is by DESIGN the recommended OCI's and oils fall well short of 'best practice protections'. Proof isn't hard to find. GM Ecotec I-4 2400 breather system and cold start PCM tuning has killed more motors and resulted in more litigation for those that used the 'recommended' practice than GM could bear. What was their response? SHORTEN THE OCI. TWICE.    I don't know how long to leave oil in an I don't know how the oil will respond to MY circumstances and because I don't and can't blanket statement or anecdotal evidence my way out of it.....I TEST and FIND the right OCI for the oil I CHOOSE. There is no shortcut but there is blind allegiance. I don't blindly trust anything.    People hear the word 'detergent' and believe that in the context of oil it means the same thing as laundry soap... Only in the most rudimentary way. It's the first additive to give up on you and they are putting less and less with each new API standard. Solvency can be used but it cost. Some unique undisclosed chemistries can be used. Valvoline R & P in example. OEM's haven't an interest in anything they see as limiting market participation. Whatever.
