The high reving is it first time you use your truck of the day? What’s happening is when it shifts from 1st to 2nd the trans seems like it slipping then grab? If so “supposedly” it’s normal according to dealer mechanics? I think it’s an issue and that’s what they’re told by GM to say! I actually went to another dealer and it was like they had a script word for word excuse . Another thing you might look into is the AFM/DFM Disabler which disables auto stop and cylinder deactivation

I can’t stand factory or round steps I found these by HDX DROP NERF STEPS . I have a 2020 Chevy Silverado 1500 they cost $539 but worth it there heavy duty and tuck up under rockers with just step hanging down . I’d recommend put some undercoating on the removable steps they aren’t powder coated very well.scroll past blank spot for pictures . Simple to install, I did mine by myself.

Anyone who bought the Autostop (AFM)disabler you realize it just controls the auto stop system? You truck still has the the DFM fuel management system the eliminates cylinders when less power is needed which can cause other issues . Ranger has a product that handles both and it plugs into the main plug underneath the dash . Your truck runs on all cylinders and doesn’t shut off at stops. It cost $149 when I got it in 2020. Hope this helps

Not sure about the parts but after relocating the wire plow has been fine except the module where everything plugs into underneath the hood the plugs need to be on the bottom otherwise water will sit in pocket where the plugs are and rot out the connection pins . They did that to mine and had to replace harness and module

I had the same exact problem after several trips to dealer /fisher plow installer the small red wire into the fuse box under the hood needs to be run into the fuse box inside can on passenger side, fisher changed location but didn’t tell distributors. Also that BS about aftermarket plow Chevy doesn’t make one , went through that BS also . Hope your already all set by now!

Shortly after purchasing a 2020 Chevy Silverado 1500 with plow prep I had an authorized fisher dealer install a fisher plow frame and wiring harness. A couple months later the truck wouldn’t start, half a dozen error codes. Brought the truck to the dealer to be told they won’t touch it because I had an “aftermarket “ plow setup installed. After much debate they did evaluate it only to blame it on the plow. So the truck was fine for about another month or so then dead battery so back to the dealer only to be told my warranty is void because of aftermarket plow installed by a fisher plow dealership. After much finger pointing it turns out that it actually was the plow in 2020 fisher changed the location of the power feed from under the hood to a fuse panel in the cab. Finally my new truck was working like a new truck until this winter when I hooked up the fisher plow and shortly after I noticed the plow lights and directionals weren’t working but the truck lights/directionals worked fine. Also the plow worked fine too just no lights. Checked the fuses but while inspecting everything I noticed the wires with the mesh casings that goes to each of the headlights was just hanging out no grommets on the headlight buckets no electrical tape just a hole in the headlight bucket? Anyone experiencing similar problems? I saw that the 2020 Chevy Silverado 1500 where having issues with wiring/plow prep wiring? Any help would be appreciated. Thanks Rich
