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.

Full-size trucks are the best and worst vehicles in America

You don’t need me to tell you that Americans love pickup trucks. And the bigger the truck, the more likely it seems to be seen as an object of desire. Monthly and yearly sales charts are something of a broken record; track one is the Ford F-Series, followed by the Chevy Silverado, RamÂ’s line of haulers, and somewhere not far down the line, the GMC Sierra. The big Japanese players fall in place a bit further below — not that thereÂ’s anything wrong with a hundred thousand Toyota Tundra sales — and one-size-smaller trucks like the Toyota Tacoma, Ford Ranger and Chevy Colorado have proven awfully popular, too. Along with their sales numbers, the average cost of new trucks has similarly been on the rise. Now, I donÂ’t pretend to have the right to tell people what they should or shouldnÂ’t buy with their own money. But I just canÂ’t wrap my head around why a growing number of Americans are choosing to spend huge sums of money on super luxurious pickup trucks. Let me first say I do understand the appeal. People like nice things, after all. I know I do. I myself am willing to spend way more than the average American on all sorts of discretionary things, from wine and liquor to cameras and lenses. IÂ’ve even spent my own money on vehicles that I donÂ’t need but want anyway. A certain vintage VW camper van certainly qualifies. I also currently own a big, inefficient SUV with a 454-cubic-inch big block V8. So if your answer to the question IÂ’m posing here is that youÂ’re willing to pay the better part of a hundred grand on a chromed-out and leather-lined pickup simply because you want to, then by all means — not that you need my permission — go buy one. The part I donÂ’t understand is this: Why wouldn't you, as a rational person, rather split your garage in half? On one side would sit a nice car that is quiet, rides and handles equally well and gets above average fuel mileage. Maybe it has a few hundred gasoline-fueled horsepower, or heck, maybe itÂ’s electric. On the other side (or even outside) is parked a decent pickup truck. One that can tow 10,000 pounds, haul something near a ton in the bed, and has all the goodies most Americans want in their cars, like cruise control, power windows and locks, keyless entry, and a decent infotainment screen.

Pickup sales may hit 2M units for first time since 2007

Even as fuel prices creep back up, trucks are still a hot item among new-vehicle shoppers. To see how popular pickup trucks still are, you don't have to look any further than how much effort automakers put into the continual one-upmanship of their trucks. Backing this fact up, USA Today is reporting that the segment could top two million sales this year - a total not matched since 2007, though still far from the pre-recession, three-million-unit levels.
Through August, the Ford F-Series continues to be the segment leader with almost 500,000 units sold, but the Chevy Silverado (328,269), Ram 1500 (234,642), GMC Sierra (122,232) and Toyota Tacoma (110,293) are all seeing at least 20-percent sales increases, helping to account for around 1.44 million truck sales so far this year - not including possible outliers like the Suzuki Equator and Chevy Avalanche.
This year alone, General Motors has completely redesigned its fullsize trucks, Ram and Toyota have significantly updated their offerings, the next-gen Ford F-150 will be out next year and Nissan is promising an all-new Titan around the same time with an eventual Cummins diesel under the hood. It would seem, then, that truck sales are poised to continue their upward trend.
