Excellent! Thank you so much for this information. I will be contacting them as you suggest.
Agreed. Which was the intent of my original post. Was my vehicle and outlier? Or were my symptoms being experienced by other Sierra 1500 owners? I have gotten into the habit of asking people who drive the same truck about their experience. All of them cite the same problem. Anecdotal data to be sure, but...... Also, one Service Rep told me 'off the record' they see an average of two vehicles per week with the problem.
Thanks, I appreciate that contact. I may give him a shout at some point. And your point about 'no guarantees' is well taken. Maybe some of my disappointment is driven by having owned two Fords (Explorer & Ranger) for 15 years with zero perfomance or operability problems.
Um.... what makes it infamous? How about the thread on similar GM truck transmission issues that stretches for 25 pages elsehwere on this forum? How about GM stonewalling both through their dealerships (I've visited two) and via their Customer Care organization (they did nothing with my case after 1 month of back and forth)? And I'm unclear as to what you find humorous about GM selling premium priced vehicles fully aware they are equipped with transmission design faults. But thanks for the insight on tire shake. alex
Good Day All. I own a 2016 GMC Sierra 5.3 V8 with equipped with the 8 speed transmission and 12,500 miles. After about 6 months or so, I began to notice a distinct 'clunk' when upshifting at moderate to light acceleration. Initially, I ignored it, since it was random and occurred relatively infrequently. Since then, the hesitation & clunking has increased in frequency, especially on cold morning starts when taking the truck out after sitting overnight. Subsequently, I did a search of this forum and others, and saw other 8 speed Sierra/Silverado owners were experiencing these same symptoms. I then brougth the vehicle to two separate GMC dealerships for diagnosis and got the usual "we were unable to reproduce the problem", or "GM considers this normal operation" answers. I then initiated a compliant with GM Customer Service, was assigned a case #, and over a month or so had to escalate the issue twice due to slow response. As of this morning, I was informed that: "GM consders your complaint and description of symptoms as normal operation, therefore your case is being closed." So, my question is this. What is the consensus as to GM's current position on the 8 speed transmission performance issue as of this date? The forum reseach I did earlier indicated a range of experiences including: "the dealer did nothing", "software reprogramming", "a TSB will be forthcoming", "the dealer took apart my transmission apart", etc etc. I realize many threads exist on this topc. I was hoping to get an update on recent experiences. I just wanted to have my facts straight should I decide to continue the battle with GM. My disappointment is rooted in the fact that the price sticker for my $57k truck didnt show transmission clunk as one of the options. Thanks in advance.
