I just picked up a 2017 Denali 6.2 with the 8L90 just over a month ago. Noticed the same things on the shifting. Delayed from Reverse to Drive, and Park to Reverse or Drive. The clunking was noticeable too, but I'm new to the 8 speed and this body style (went from an 09 Tahoe 5.3 with 6 speed). Just over a week and a half ago, the P0711 code came on for the trans fluid temp sensor. Carried it to the dealer and thankfully I got an extended warranty. They pulled the pan and found metal in there and said the torque converter was bad. Now i'm waiting on them to source a new tranny and torque converter. Been in the shop a week today. Good times!

Thanks. Was just trying to find a part number or see if anyone knew the correct name so I could search it. Just aftermarket soundproofing comes up when I try. I'll see if I can hit up a junk yard or something and see if I can score anything there first.

Hi gang, new to the forum here. Just picked up a 2017 Sierra Denali 1500 CCSB a couple Saturdays ago, and love this truck! The previous owner had installed an aftermarket amp at some point, as all the wiring is still behind the rear seat. However, it looks like they removed all of the material that normally goes on the back of the cab (item 8 in screenshot below). I've found this diagram on a few websites, but no way of actually ordering it. Does anyone know the best way to get this or if there is any aftermarket direct fit replacement for this? No idea what it's called, so apologies if the subject is incorrect.
