Hello all,

This is my first post on the forum and I’m fairly new to the truck world. I just went from a barebones 2018 Colorado to a new 2020 Sierra SLT 4x4 with the 5.3L this week. A few questions I had right off the bat that I’m curious about is the off road modes on it. I don’t plan on doing much or any off-roading in it, and too be honest I’m not sure how capable it is not being an AT4. Anyway, I noticed it has an Off-Road mode on the mode dial but there’s also a button for a Terrain mode. I was curious about similarities and differences between the two. Also, how is the Sport mode? Noticeable differences between that and normal? Sorry this is so long, but I’m excited to get out there and test it out but wanted some advice before I do. Thanks so much.

My second truck of this line and I've never touched the offroad option.

 

Sport really only extends shift points and makes them more aggressive and is noticeable. 

 

In all truth, I cant really tell a difference between sport and tow modes.

 

But, with tow mode, the trans temp gauge appears on the upgraded dash.

 

Enjoy the new ride.

It is plenty capable off road. No need for the at4 to be capable off road and i own an at4. All the at4 really gives you, capability wise, is a little more ground clearance. For decades people used gm trucks off road before there was a lifted option.

Is there a way to monitor trans temp without the all-screen dash? I haven’t really gotten a chance to look around yet and I’m doing my best to follow the recommended break in so I haven’t explored much.

I dont know for sure  on other models, but the trans temp is displayed  in the information menu.  May have to be enabled.

Haven't used off road mode yet, but sport mode does change the shift points and the steering is heavier. I do prefer sport mode on curvy roads, use tour for everything else, wont get to try off road til this summer, if the virus lockdowns are gone and I can get away for a bit.

      2007 Silverado classic Cooling fan running

      I am having similar issues.. 08, 4.8L granted I did had a fender bender and minor damage up front passenger side but I don’t think it had anything to do with it.. I had the high and low pressure checked and my fan for my radiator keeps coming on.. replaced the pressure switch and don’t want to keep throwing parts at it. I did have some minor problems here and there like on long road trips sometimes the ac would get a little warm and then on the highway as soon as I give it a little gas or get a little heavier on the petal it started running cooler. Never had an issue with the ac besides the here and there.. but I also started having issues when I fuel up now it takes a bit to start ( super embarrassing) it runs fine and once started ( only happens after fueling up) starts fine any other time. Could they be related?

      Spent a small fortune on fuel this weekend.   $6.69 diesel, 18 gallons of that. $6.99 92-octane ethanol free, 10 gallons of that for yard machines $5.59 87-octane for one of the cars, 11 gallons.   $250+ and I didn't even get a tug.   Hormuz ain't Hormuzin again, did not see that coming...LOL

      Appreciate the advice. I've watched multiple videos. Most showing the most complex for those that have a center console, to one that showed maybe 2 pieces of trim being removed, like 6 screws, pulling back the screen and switch assembly, and installing the inline module. And this was a new/newer Silverado. That didn't look too bad. All the others show alot of trim pieces that need to be removed. I've broken those kind of tabs/clips on my C8 Corvette trying to get to the battery, and that was a lot less clips than what I think is involved here after watching multiple videos and looking at my dash today. I have one on the way. Called a reputable stereo place about installing it and got a "minimum" price of $175. Ouch! Looking forward to seeing what the instructions have to say.

      Ac not keeping up

      Hard to say what the issue might be. Anything from the ability to cool the AC condenser up front, to blend door issues in the HVAC unit, to refrigerant charge, to compressor issues or issues in the lines.   Report back what the techs find on the 29th.   GM has service publications which list acceptable vent temperatures and AC pressures at given ambient temps and humidity. They probably won't touch the system if it's operating within those ranges.   I'm also surprised to hear your 2024 with the L8T is still using R134a? I was pretty sure the HD's had switched to the new refrigerant around 2020.
