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.

Chevy, GMC and Ram dealers are worried they'll run out of new pickups

One of the unexpected side effects of the ongoing coronavirus pandemic is a shortage of pickups at Chevrolet, GMC and Ram dealers. Supplies are running out, and the factories that build these trucks remain closed. Stores across the nation began increasing incentives in March, when the first stay-at-home orders were issued, in a bid to continue luring buyers into showrooms. They also launched online sales channels, or expanded their existing digital business. Sales nonetheless plummeted in April 2020, but in-demand vehicles, like the Ram 1500 and the Chevrolet Silverado, are still selling relatively well thanks in part to the aforementioned incentives. Pickups outsold sedans for the first time in April 2020, according to The Detroit News, by 17,000 units. The problem is that General Motors, Fiat Chrysler Automobiles (FCA), and Ford temporarily closed their factories in March. "The pipeline is very dry," said Mike Maroone, the CEO of a large dealership group named Maroone USA, in an interview with Automotive News. He told the publication his Chevrolet stores are sitting on a 30-day supply of the Silverado, which is one of America's best-selling vehicles. "That is a problem for us," he concluded. Coronavirus-related lockdowns and factory closures compound problems already faced by dealerships who represent General Motors-owned brands. They entered 2020 with a thinner inventory than a year earlier due to the 40-day United Auto Workers (UAW) strike that paralyzed the company late in 2019, and the 0%, 84-month offers announced in March have sapped supply. Ram wasn't affected by a strike, but it has relied heavily on generous incentives to move trucks off lots. Ford, on the other hand, limited incentives to 2019 models. Inventory levels differ greatly from region to region. The national average for the Silverado stood at an 82-day supply in March 2020, down from 120 in March 2019. Ram stores had a 114-day supply of the 1500 (compared to 134 a year earlier), while Ford bucked that trend with a 111-day supply versus 84 in 2019. Don't panic if you're in the market for a truck; we're not facing a complete drought. Automotive News added that America's light-duty pickup inventory could fall to 400,000 units by the end of May, and drop further to 260,000 units in June. For context, there were about 700,000 light-duty trucks in stock in May and June of 2019. That's unquestionably a sharp drop, but there will still be over a quarter of a million trucks to choose from.

Chevy Corvette Stingray picks up another award, this time from Automobile

The new Chevrolet Corvette Stingray has picked up another buff book accolade after capturing Road and Track's Performance Car of the Year award. The seventh-generation of America's sports car (sorry Viper, Mustang, et al.) has been named Automobile Magazine's Automobile of the Year.
Automobile's award to the Corvette over competitors is the mirror image of its rival Motor Trend, which named the Cadillac CTS its car of the year over the C7. The CTS was, according to the Automobile team, the closest contender to the mighty Stingray. Great news all around for General Motors it seems.
As for what pushed the Corvette past its distant, four-door cousin, Automobile commended its excellent, 6.2-liter V8 calling the car's performance "simply awesome" while also remarking that it is easier to drive fast than ever before thanks to steering and chassis tweaks. Following a theme set by other publications, there were also plaudits for the interior, of all things, with the buff book complimenting the car's ergonomics and material quality, while also praising the standard seats.
