Bought a 2019 Colorado with 2000 miles on it. Just after warranty expired, transmission started the shutter problem. Took it to dealer and they told me it was a known problem of wrong fluid in transmission. They did a flush and put correct fluid in. Charged me $600. Should have been a recall item imo. But not had any issues since. Almost 69K miles on it now
