2017 Tranny Shake

So I bought my first brand new truck (2017 Chevy Colorado LT) after hydroplaning and totaling my '04 Chevy Colorado a few months ago. When I start the truck in the morning and shift from Park to Reverse or Park to Drive with my foot on the brake the tranny shakes a little. Now if I then shift into neutral or Park the shake goes away. I also feel the shake at stops until the tranny warms up. Dealer installed an exhaust damper to lessen the vibration and said that GM will be issuing a software update to raise the idle from 600 to 750. They say the idle is dropping kinda low and others are complaining about the same thing. Is anyone else experiencing this issue? Any advice would help. Thanks

I have a stumble that developed under the same condition, but won't consider it shaking. Good to hear a software update might be available when I take it in for a free oil change.

I do agree that the in-gear idle needs to be raised, but neither my wife's nor mine exhibit this. We both usually remote start about a minute before heading out the door.
