I've been wondering about these transmissions, in particular how they shudder between low gears when accelerating and coming to a stop. What's the deal with the options on approaching this issue? What is a fast relearn from the dealership? When is a relearn good to do? How does a transmission 'learn'? Think Amsoil would fix this problem? (certainly fixed the rough shift in my 2015 Sierra). Is it a solenoid issue? Just want some opinions on how someone more knowledgeable would approach this. Thanks.

Mine gets better all the time.  The more I drive the more it learns apparently.
