No, just straight up poured too much in. Oil level is over the "full" mark on the dipstick. It sounds like if you do or did, you would drain it off with the valve. I use magnetic drain plugs, so draining off any to come down to the full mark would be more difficult. The 'range' of acceptable fill level keeps from having to be so exacting with the dipstick, filling, draining, etc. -

My take: I don't think seeing up to 200k on the odometer of any of these engines/trucks (2014-to present) is surprising. (Excluding the known DEFECTS, specifically, the 6.2 main/connecting rod bearing issues, the defective lifters, alternatively parts that a recall was issued for - I think there were three.) 250K is my line in the sand, anything over that is 'surprising', but not limited to the engine making it that far but including the truck surrounding it too. (We've talked about this in other posts, why I think the engine isn't the deciding factor for ultimate mileage.) -

I included the first gen-cylinder de-activation (active fuel management) in my statement. -
Hello All! My 2019 Colorado 3.6 LT, 4WD Crew Cab has approximately 77,500 miles and I recently began experiencing the well-known transmission shudder between about 30 and 65 mph. The problem had worsened to the point that I could no longer attribute it to road conditions - and I had decided to bring the truck to the dealer - when recently, I experienced a sudden loss of power while driving at maybe 40 MPH. Several warning lights flashed, the “Check Stabilitrack” message appeared, and the Check Engine, Stabilitrack, and Traction Control icons remained illuminated. The truck regained driving power, but it stayed in a low gear with unusually high RPMs for the speed. (limp mode?) Because I was only about two miles from home, driving slowly, I was able to make it back and run an OBD-II scan, which showed fault codes U0101, P0700, and U0100. My next trip in the truck was to drive it to the dealer the following day. That trip began normally, but after about a mile I experienced another loss of power, along with the same warning lights and the same “Check Stabilitrack” message. As before the truck remained driveable, but again operated at an abnormally high RPM-to-speed ratio and seemed stuck in a single gear. About a mile later, the dashboard lit up once more, this time displaying “Check 4WD.” Soon after that, I arrived at the dealer. I have verified that the truck still has its original factory transmission fluid, which means it has never received the corrective fluid exchange outlined in GM Technical Service Bulletin #18-NA-355. That was Thursday of last week and I've heard nothing yet from the dealer. According to Technical Service Bulletin #18-NA-355 and the build date of my truck, my truck should have the newer LV fluid. I've done a little research and read something about a problem with the wiring harness as well. Anyone have an insights into this situation? Thank you!!
