I have a 2019 Silverado High Country that has given me transmission problems to include the shuddering, a hesitation to engage in gear when parking and suddenly dropping into gear lurching me forward (a safety concern of mine), and hard shifting, e.g. sporadically both up and down shifting, and from reverse to drive and visa-versa. I've taken it into the dealer I purchase the truck from twice. The first time I was told that "it is normal", and there "were no codes stored in the computer regarding any abnormality". The second time I carried it back to the dealer I let them know I was made aware of a class action lawsuit. I was told the problem was caused during assembly; that too much lubricant was used on interference fit components not utilizing a key. They said there was a technical Service Bulletin to flush the transmission. This seemed to take care of the problem initially, but the hard shifting has again reared its' ugly head.

Oddly, well really not oddly, at about 3,000 miles on our 2015 Corvette Stingray, we experienced the shuddering problem; about the same number of miles as the truck. Unfortunately for us, we hadn't driven the car much, so the original factory warranty had expired. We had purchased at a cost of roughly $3,000 an extended warranty offered by GM through Ally. I figured it would be covered, so I carried the Vette in for the "fix". I was told that fluid changes weren't covered by the warranty, even though the dealer told me this time that the wrong fluid had been used, that GM hadn't developed the proper transmission fluid at the time of production. I guess they only realized it later when these problems began to surface. I had to pay the cost out of my pocket.

So, how do you reckon I feel now, realizing this flush is only a temporary solution. I'd sure like to get in on this class action lawsuit, and sincerely hope that GM is made to properly remedy the problem. When GM has their dealers lying to customers, it's no wonder there aren't more complaints.
