2020 Chevy gas harsh downshift
TrucksAndDogs replied to Nathan Leslie's topic in Troubleshooting, Warranty & Recalls
2020 GMC 2500 Diesel - have had for 4 weeks .... have experienced a harsh downshift a couple of times. Certainly not frequent. Trying to notice what conditions it occurs ... recall it happening once while on a slight forward incline.
