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.

2015 Chevy Silverado Custom Sport is subtle in black

In a world where trucks are growing bigger, bolder grilles and more muscle-bound looks, Chevrolet is trying something a bit different with its recently revealed Custom Sport edition for the 2015 Silverado at the this year's Detroit Auto Show. The edition leans on being understated, instead of screaming about its abilities. The design is supposed to be a throwback to the Chevy Custom Sport Trucks of the late '60s that brought a touch of elegance to these usually utilitarian vehicles at the time. The heart of the package is its monochromatic body-color touches for the bumpers and grille surround. The one on display at the show is especially attractive with a chrome-accented black grille that fits perfectly with the rest of the body. The edition does get a bit more shine with chrome covering the 20-inch wheels, door handles, mirror caps and side moldings. In addition, buyers get projector beam headlights, tow hooks and heated power mirrors. The custom package is available on the LT trim in black or white and on the LTZ in black or White Diamond Tricoat. Take a look at this monochromatic take on the Silverado as it sits in the Motor City. 2015 SILVERADO OFFERS CUSTOM SPORT PACKAGE Inspired by Chevy Custom Sport Trucks that helped launch personal-use pickups DETROIT, 07/01/15 – With the new 2015 Silverado Custom Sport special edition, Chevrolet pays homage to one of its most iconic pickups, adding a sophisticated monochromatic look to double- and crew-cab Silverados. The Custom Sport package features body-colored front and rear bumpers and a body-colored grille surround with a chrome-accented black grille. Other accents include 20-inch chrome wheels, chrome door handles and mirror caps, and chrome body-side moldings. The package also includes projector beam headlamps, tow hooks and heated power-adjusted mirrors. "The Custom Sport special edition was inspired by Chevy Custom Sport Trucks of the late 1960s," said Sandor Piszar, Chevrolet Trucks marketing director. "Those CST models added a touch of elegance to a great all-around truck, just like the Custom Sport package for the new Silverado." The redesigned 1967 Chevrolet pickup entered the market at a time when trucks were starting to move off the jobsites and into the driveways of cities and suburbs. The 1967 Custom Sport Truck, with its bright trim, plush carpet and bucket seats, helped launch a wave of personal use pickups that continues today.

Chevy Bolt officially keeping name, says marketing boss

There might be just a little confusion at first, but the Bolt name is sticking around. After conducting two consumer studies into the name, Chevrolet isn't worried about the similarity of the monikers for the upcoming EV and existing Volt plug-in hybrid. In fact, the brand thinks the resemblance might be for the best. "The decision is made. The name won't be changed." Chevy head of marketing Tim Mahoney said to The Detroit Free Press. The research shows that the compatibility between the two names actually works quite well. With the Volt well established, people apparently already connect the Bolt to the Bowtie, which is just what a brand wants. Both studies indicated the ""same result, it did well," according to Mahoney. Just a few months ago, the future of the Bolt's name wasn't so clear. GM North America President Alan Batey said the company knew there might be confusion, and it was still mulling its options. The Bolt could be a breakthrough in the EV market with a 200-mile range and a possible price of around $30,000 after incentives. Production is set for the Orion Assembly plant in Michigan following a $200 million upgrade there, and the model could be in dealers as soon as 2017. That's just in time to take on the Tesla Model 3 with its claimed $35,000 price and similar driving distance as the Chevy. Related Video:
