Purchased new 2019 Colorado Z71 4X4 January 31 2020. Transmission shudder at 500 miles, fluid changed, helped for about 1000 miles. At about 1700 miles it is now slamming into 2nd & 3rd gear when leaving the house in the morning. Sometimes it is very rough shift, other times not so rough. Now at 2200 miles. Called dealer & explained that the shudder is gone, but that it hard shifts mostly on first start up or if it has been sitting. Told I have 36000 bumper to bumper and 5yr/60,000 on powertrain, so if it gets worse I am covered. Really like this 2019 Colorado, just not the shifting. Should have kept the 2015 Colorado, but couldn’t resist the deal of a left over 2019.
