GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.

2021 GMC Yukon will pull a 180 thanks to a Hurricane Turn feature

GMC isn't a hip, young startup, but its engineers are out to prove it's possible to teach an old dog new tricks. The next-generation Yukon will offer adventurers seeking a quick turn-around a "Hurricane Turn" feature that functions a lot like Rivian's Tank Turn technology. The two systems use different hardware to perform a similar action. We didn't hear anything about the Hurricane Turn feature during the Yukon's unveiling because GMC planned to keep it under wraps until later, but an eagle-eyed report at Motor Trend uncovered it and quizzed the firm. It's real, and it's engaged when the driver switches the stability control system off, energetically turns the steering wheel in either direction, and mashes the accelerator pedal to the floor. The Yukon needs to be on a loose surface, too. If you're turning right, the on-board computer applies braking power to the passenger-side wheels to prevent them from spinning, while the engine continues to turn the driver-side wheels to rotate the Yukon on its own axis. The exact opposite happens if you're turning left. It's clever and relatively simple; there's no extra hardware required to enable the feature, though it shows the next Yukon is far more advanced than its predecessor. It goes without saying that only four-wheel drive models will receive the Hurricane Turn feature. There's no word yet on whether it will be compatible with all three engine options, or if it will be limited to a certain trim level. GMC will publish additional details about the system, and hopefully a video of it in action, in the coming months. Rivian, on the other hand, leveraged its four-motor electric powertrain to teach the R1T (and presumably the R1S) how to pull a 180. The right wheels turn in the opposite directions as the left wheels – hence the name Tank Turn – to spin the truck around like a CD in a Walkman. Its system doesn't use the brakes. The 2021 Yukon is due in showrooms in the summer of 2020, and Amazon-funded Rivian won't start making the R1S until the end of 2020 at the earliest, so GMC will beat its younger rival to the punch. What remains to be seen is how often motorists use either function. We're betting not very once the initial novelty wears off. Related Video:    

Autoweek dubs GMC Canyon, VW GTI its 2015 'Best of the Best'

For kids around the globe, tis the season for Santa, reindeer and presents. For the automotive industry, the last quarter of each year is reserved for awards, whether they come from Motor Trend, Car and Driver, Automobile, or yes, Autoblog. The latest to get released comes from our friends at Autoweek. The magazine has echoed other outlets, naming a Volkswagen hatchback and a small pickup from General Motors as its Best of the Best. Unlike Motor Trend, which handed out its golden calipers to the Chevrolet Colorado and Volkswagen Golf range, Autoweek doled out its awards to the Colorado's twin, the GMC Canyon, while singling out the hottest version of the Golf, the GTI. "This is the best hot-hatch on the American market – and it may be the best car you can buy for less than $30K," one AW staffer said in the publication's article on the feature. Other staffers praised the absolute value provided by the GTI and the overall fun factor. The Canyon, meanwhile, was saluted for being "the perfect size," not to mention its excellent build quality, feature-rich cabin and overall practicality. "It's truly a truck in the most honest sense of the word," Autoweek wrote of the Canyon. Scroll down for the full press release on the announcement from Autoweek, which includes comments from both Volkswagen and GMC. And then head over and read AW's full feature on the awards. Autoweek names Best of the Best/Car and Truck for 2015 Volkswagen Golf GTI and GMC Canyon signal a strong year for design, performance and value DETROIT, Dec. 16, 2014 /PRNewswire/ -- Today, Autoweek named the Volkswagen Golf GTI as its Best of the Best/Car for 2015, beating a group of finalists that includes the Alfa Romeo 4C, Ford Mustang and Mercedes-Benz C-class; and the GMC Canyon as its Best of the Best/Truck for 2015, besting the likes of the Chevrolet Colorado, Lincoln MKC and Porsche Macan. Autoweek evaluates every new or significantly updated model throughout the year and begins to identify the standouts. Performance, economy, fit and finish, design, value, significance to the auto industry and personal taste all combine to define the Best of the Best. Four cars and four trucks make the grade, and Autoweek editors put them through rigorous road-handling tests at Michigan International Speedway in Brooklyn, Mich. This is where a vehicle transcends the numbers and shows if design, performance and pure driving passion meld into an Autoweek Best of the Best pick.
