Differences Between My 2019 and 2020 silverados


Recommended Posts

Posted

Well now that my buyback is complete and I have had the 2020 Duramax for almost a week let me point out a few differences I noticed. First of all the 2020 rides stiffer in a good way. Gone is that swaying/ bouncing and old time Cadillac wallowing when driving on wavy pavement surfaces. They either changed the springs, shocks or both for the better. This gives the 2020 a much more solid feel on the road. They also changed the power steering feel it’s not as loose and vague at lower speeds as the 2019 was. The infotainment system no longer has a mind of its own adjusting the brightness improperly for day and night lighting. They have added some cool new menus to the DIC including one for towing angle and vehicle angle. The radio has a few new menus as well. The big winner on the 2020 is the 10 speed Ford/GM transmission it never hunts for a gear and never have I felt a rough or inappropriate down shift or vibrations like in my 2019. Of course having the diesel I don’t have cylinder deactivation so this could be why the vibration is gone as well. The Duramax is pretty incredible on mileage over the 5.3 it’s very noticeable. Both trucks are non Z51 crew cab  LTs.

I'm soon to pick up my 2020 Chevy 3.0 LT and am I to understand that the 3.0 diesel does not have a start/stop?

Diesels do have start/stop.

Unfortunately it does have start stop.

Went ahead and installed the Autostop Eliminator, no more pushing the button to turn it off, now the default is off and when you push the button it turns on.

can you elaborate more about the autostop eliminator,

How’s the power on the 3.0l compared to the 5.3? I’m considering getting rid of my 2019 for the 2020 solely for the 10-speed transmission. I really don’t need 4wd so the only way to get the 10 speed in a 2wd is with the diesel.

Amazing at full throttle it stay's in the sweet spot pulls really hard in all ten gears plus with two wheel drive you should be able to get 30+ mpg. Overall, I think this is the best half ton truck out there and I've had Ford, GMC, Chevy, Toyota and Honda Ridgeline. Normal driving, it's hard to tell when the transmission shifts. With a gas engine you really have work the RPM's to see the power, but with the 3.0L the power never drops off.

It’s almost the same feel. It’s seems to be a good motor.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
