Sajeev,

Long time listener, first-time caller. I’m responding to your plea for new Piston Slap questions. I purchased a gently-used 2008 GMC Yukon Denali AWD a couple of months ago. Other than its appetite for fuel, the only negative is that it has 141,000 miles. I believe the previous owner changed the transmission fluid at 100,000 miles (Carfax shows that the transfer case fluid was changed at this point, and I can’t imagine doing that and not doing the transmission). The fluid was relatively clean but I changed out several quarts via the dipstick tube using a fluid extractor after I purchased the vehicle, replacing them with the specified Dexron-VI. I believe the fluid level is correct but it’s difficult to read.

On a recent road trip, the 6-speed automatic (6L80E) transmission stumbled during the 2-3 shift while driving through the mountains and went into a failsafe mode. The check engine light came on. I pulled over, turned the ignition off and on again, and the truck operated normally. The CEL remained on for the next several ignition cycles. When I called OnStar to obtain the fault code, they could not retrieve it because the CEL was no longer on.

General Motors is revealing its updates to the 2016 GMC Sierra lineup days after Chevrolet revealed its new face for the 2016 Silverado.

In a video posted to its YouTube channel (via Automotive News), GMC trotted out the new front fascias, bumpers and C-shaped LED daytime running lamps for the full-size pickup.

Autoblog reports Volkswagen Group of America executive vice president of group communications Tony Cervone is returning to the GM fold as the automaker’s senior vice president of global communications. According to CEO Mary Barra, Cervone “brings an ideal mix of outside perspective and experience that compliments a deep background in GM and today’s global auto industry.” Prior to his return, he also served as the vice president of communications for United Airlines and Chrysler Group, where he spent 14 years before his decade-long previous service to GM. Cervone succeeds Selim Bingol — who resigned from the company in April “to pursue other interests,” and will report directly to Barra.

Following in the footsteps of the Ford F-Series multiple luxury times and Ram Laramie, Chevrolet will offer a new luxury trim level for the Silverado – complicating things for GMC, which is positioned as an upscale truck brand.

With its minivans and conventional midsize SUVs discontinued, GM relies heavily on its large “Lambda” crossovers—the Chevrolet Traverse, GMC Acadia, and Buick Enclave—to serve the family market. With over 230,000 sold in 2010, they’re easily the best sellers* in the segment. In comparison, Ford shifted only 34,000 Flexes. But, now in their fifth model year, the Lambdas are getting old. With cash short leading up to the bankruptcy, what might be done on the cheap to maintain buyer interest? The winning answer: a new Denali variant of the GMC Acadia.

GM announced today that Buick-GMC sales manager Brian Sweeney has been promoted to the top spot at Buick-GMC after his predecessor Michael Richards left the position after nine days on the job. According to the Detroit News, Sweeney began his GM career at GMC in 1990 and has served as vice president of sales at Saab Cars USA and sales manager of GM’s north-central region.
