The first one was after 6000 miles. A large clunk sound and vibration occurred after shifting gears in the 30 mph range. The dealer told me this was a know issue related to the transmission manufacturer lubricant conflicting with the GMC transmission fluid. They did a flush and replace and for a time period it settled down. I have 56,000 miles now and the latest complaint I made was when nearing a stop at 5-10 mph the transmission did a massive clink. I had two others in the vehicle that observed this over 20 times. I immediately scheduled a service to look at this. After 4 hours they told me nothing is wrong. Since then the transmission has a light clunk shifting at low speed so I wonder if they lied and flushed the fluid. They said no metal was in the fluid. Online websites show many posts of owners hanging this issue. I was never shown a bulletin on any reported issues and would like to see every one related to the 8 speed transmission. My standard powertain warranty has expired after 5 years. I fear the value of this vehicle is impacted by so many complaint, no action by NTSB, and questionable practices by two GM dealers that serviced my vehicle. I would like to see a recall as this isn’t just my issue. I would like to see what investigation NTSB has done on this topic.   I have printed service re odds for each I have complained about the transmission and now believe the dealer was aware of the issue and GM bulletins coached them how to tell me there is no issue. The last statement made was also odd, the service advisor told me that  the clink is because the transmission sometimes goes from 3rd to 1st and skips second gear. I was charged to have them look for a problem  and if this a known issue to both GM and the NTSB shame on you both.","products":[{"type":"Vehicle","productYear":"2017","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]}]}
