Can you have Z71/All-Terrain Inclinometer added to digital dash cluster?

I have a 2019 Sierra 2500HD Denali 4x4 Crew Cab.

It has the Hill Descent option, but does not have all terrain/Z71.

I imagine it has the accelerometer to make the z71 inclinometer work since it needs to be able to detect when its going downhill to turn on the hill descent mode.

 

Wondering if there's any companies that can reprogram the digital dash cluster to add in the offroad inclinometer, or if I have to get a different accelerometer too, or if I would just have to get a different digital dash cluster altogether.

 

Not sure of anywhere else to ask this....I'm also having a hard time figuring out what comes with z71 option, all-terrain option, and then when you have both (which seemed to be an option as a gmc....I'm not sure if thats true but it looks like it) besides all the decals and interior emblem stuff - more referring to the functional features/upgrades.

I know on silverado, z71 had that inclinometer, different shocks, skid plates, I think it changed your diff ratios, and it gave you the auto 4x4 select option.  Only recently found out that hill descent package is NOT a part of Z71/all-terrain only.

Below is pic of inclinometer I was talking about.  I'm guessing its tied to the auto 4x4 feature based on the AWD text that changes depending on what mode you're in - which is tied to z71 if I remember correctly

2019 HD Denali 4x4 should have that page.  (my 2018 did)

Probably just have to turn the page on in the DIC. 

 

Z71 does not change diff ratio on a HD dmax truck.

All Dmax of that generation were 3.73

You're 100% right, found this out like an hour after posting.
I am kinda disappointed you can't see trans temperature like you could with GM trans.....but I'll take the improved shifting of the Allison over the random hard shifting baloney of the GM 8 spd.

 

I asked admin if I could delete my post since it won't let me.

Denali cluster will show transmission temperature when you engage tow/haul mode.

newdude beat me to it

 

 

You can put trans temp up on dic page, or the put it in tow/haul and view the gauge spot it takes over when in tow haul. 

I sometimes just push the tow/haul button to see the temp and then switch if back out of tow/haul.

You're likely to find that the allison doesn't run hot enough that it needs constant watching --- and the computer is watching anyway and will let you know if there is an issue.

I didnt see where you could get trans temp on the DIC page, I will make sure to try the tow/haul button and then navigate the pages.

 

Thanks all!

The list in the manual for uplevel DIC suggests it should be beside the 'offroad' item in the list.

Did not see it show up in the menu still.

 

Can verify that it swaps the voltage gauge out with trans temp when you press the tow/haul button on the shifter.

So, good enough for me!

 

Thanks all!

Just to verify.

You were in the list where you add/remove checkmarks to indicate which pages you want to be able to see when you go back to the info tab?

Correct,
I dont recall if I was in Tow/Haul WHILE I was in that menu, but I definitely looked through that menu and there was no trans temp one listed, and nothing happened when I right arrow or hit enter on the off-road page.

 

The only time i got anything transmission related to show up was like I said where you hit tow/haul button, the voltage gauge was replaced with transmission temperature gauge.

 

I'll try going to that menu while in tow/haul mode over lunch to see if it makes it available.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
