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.

2022 Chevy Silverado HD gains Multi-Flex tailgate as an option

GM is spreading the Multi-Pro Tailgate love around its truck lineup, and the Silverado HD is the latest pickup to gain the option. Just like the 2021 Silverado 1500, Chevy uses the “Multi-Flex” name for it in the HD, eschewing GMCÂ’s “Multi-Pro” branding for the bowtie vehicles. YouÂ’ll be able to option the tailgate on 2022 model year Silverado 2500HD and 3500HD models. ItÂ’ll be available optionally in every trim, so thereÂ’s no need to grab a more expensive trim to gain access to the trick tailgate — youÂ’re also not required to take it in higher trims. Functionality is the same as the standard Silverado and Sierra.  The primary gate opens and closes like any other tailgate out there. ThereÂ’s a primary gate load stopper that allows you to put the gate down and still keep things from flying out the back (it can also be arranged such that the load stopper is at a higher height by using the inner gateÂ’s stopper). The inner gate folds down perpendicular to the ground to allow closer access to the bed. A full-width step is available if you fold both “gates” down and pop out the inner panel. And lastly, the inner gate can be lowered to use it as a small work space. You can watch the short video above to get a quick run through of all the positions, or scroll through the gallery at the top of this post. Besides the tailgate, Chevy says the 2022 Silverado HD is gaining a new Greenstone Metallic exterior paint color. Other changes for 2022 were not detailed at this time, but Chevy says the trucks with this tailgate should be available sometime this summer. Related video:

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.
