Default 2018 GMC Canyon SLT shifting issue

I have a 2018 GMC Canyon SLT. I have noticed lately that when I slow down for some reason and then go to accelerate, it seems like the transmission shudders a bit. Anyone else experience this?

Please advise.

This seems to be a popular complaint with the eight speed, a class action suit (you know the kind that keeps lawyers rich) has been filed against GM. Most dealerships will place a different fluid in the transmission if they can duplicate the “shudder”.

I have a 2015 Canyon that does the same thing. Dealership says it is all normal.

I have a 2016, dealer stated that GM was working on a fix for this, last December! Dealer I go to, HAS TO DUPLICATE EVERYTHING, or they do not fix anything! So I go to GMC Customer Service! Then the dealer will call and say"you should have come in and talked to us"! Really? In three years I have had three issues, of which only two were fixed because I got GMC involved! Next nearest dealer is 70 miles away! Toyota dealer is 50 miles away, of which I state to the service manager! His reply, "that is up to you" To a guy who has purchased over 20 new GM's over my lifetime! One of which was in March of this year!
