My 18 is having this exact issue. I went from loving this truck to dreading the damn thing. Dealer reset tcm shift strategies.... No dice. Same schitt. Ridiculous.
They say next steps is replacing valve bodies. Opening the transmission.. down the rabbit hole he goes.

The valve body on my truck has already been replaced due to a prior issue. Still having these problems.
