Just got back from the dealer.
When I started the truck this morning and drove it to the dealer the shifting was fine but I still had a the check engine light on.
The only code showing was p0882 TCM power input low, dtc is stored and good trips present. Test drive no issues present. Checked connections to trans and pcm all ok, unable to duplicate concern at this time.
They did do unrelated updates to the bcm, ddm and radio.
I was told it could be the cold, but what the heck it's always cold in Canada in the winter
