My 2016 GMC Sierra SLT with the 8L90 transmission has troublesome that started sometime after about a year after owning this truck brand new. The problem exists primarily in lower gear shifts where at times it feels like someone hit the rear end of my truck when all it did was shift a gear. My wife who witnessed this the first time asked me "what the hell was that"? Slip, buck, kick, jerk, and harshly engage are the symptoms I experience. I did bring the truck in a couple times to the dealership when it was still under warranty who did at one time did a "power flush" of the transmission fluid which did help for awhile - maybe a month before all the shifting issues returned. I was told the other time "we could not duplicate the problem and there are no codes". On occasion while going 40 to 50 mph the RPM's will race up about 800 RPM's and then return to what the normal should be. This happens when I'm just cruising along at a steady speed. I just recently had the transmission temperature sensor cable replaced by the dealership which kept throwing a P0700 and P0711 code.
