GM recalling 426,000 sedans over faulty transmission shift cable

General Motors is recalling some 426,240 sedans that may have a faulty transmission shift cable, according to a National Highway Traffic Safety Administration report this morning. The recall concerns a fault within four-speed automatic transmissions equipped on 2007-2010 Saturn Aura models, and 2008-2010 Chevrolet Malibu and Pontiac G6 models.
The report specifies that tabs on the transmission shift cable may fracture and separate. Such a fault could cause a discrepancy between the actual position of the transmission and the apparent position of the shift lever.
GM is currently working to notify owners of the vehicles in question, and dealers will check and replace shift cables free of charge. Scroll down to read the complete NHTSA report.

New Chevrolet Silverado to be revealed on Facebook on Thursday

There's not much to see here, but if you're one of those waiting for the reveal of the 2014 Chevrolet Silverado 1500, above is the teaser image that Chevrolet posted on its Facebook page. We've seen the truck in form-fitting camo before, and even less can be made out here beyond those seriously punchy Silverado-esque fenders and the knowledge that the projector-beam headlamps teased previously do indeed work. We'll have to wait until Thursday for a full perusal of the "bold exterior design" and "careful attention given to every detail" we've been promised.
Gathering intel and rumors, magnesium and aluminum contribute to the Silverado's weight loss plan, the purported "High Country" top-tier trim will contribute to luxury pickup truck competition and profit margins and the next-generation small-block V8 will contribute to improved fuel economy. On the engine note, there have been rumors of available V6 engines, and when Facebook user John Jones asked "Where's your answer to that EcoBoost Chevy?", the Bowtie replied "stay tuned on the 13th. We think you'll be pleased...".
Along with the "Raise the Bar" tag, Chevrolet says of the Silverado, "You asked, we delivered." You can watch the reveal live on Chevrolet's Facebook page at 9:30 am EST, this Thursday, December 13. The GMC Sierra 1500 will also be there, and we'll see both in person at the Detroit Auto Show in January.

Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.
