[QUOTE="72LT1VETTE, post: 271790, member: 7169"] It has absolutely nothing to do with the prop shaft. It's the "transmission fluid". The dealer you bought it from should replace it with a revised fluid free of charge. GM never made a recall for this issue. The issue was found in 2017 or 18 and all GM dealers in the US were sent 55 GAL barrels of fluid and a special pump to remove the old fluid and replace it free off charge to their customers. Problem is with ALL GM vehicles with that automatic tranny, cars and trucks from 2014-2017. No recall because it was not severe in all vehicles. My 2016 Vet started around 15000 miles mainly during mild acceleration or in cruise when the tranny would downshift on inclines. The dealers actually have a "TECH" letter about this issue [/QUOTE]
