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.

2019 GMC Sierra Denali MultiPro tailgate and CarbonPro bed explained

When the 2019 Chevy Silverado debuted at the Detroit Auto Show in January, GM's Mark Reuss promised that the new 2019 GMC Sierra would have some significantly different styling and features than its corporate sibling. Previously, the Sierra has been little more than a Silverado with new front and rear fascias and some extra chrome inside and out. Well, Reuss was right. In addition to new sheetmetal, the Sierra exclusively gets the slick MultiPro tailgate and CarbonPro carbon-fiber bed box The tailgate really is trick. At the debut, GMC had multiple demonstrations, with engineers walking us through all six different configurations. Like all Sierra tailgates, the MultiPro version uses an aluminum skin to reduce weight. It's easy to tell which tailgate is which, as the MultiPro has a distinct cutout in the middle where it can fold down or extend. It can be used to extend the bed, drop to allow easier access, provide a sort of workbench, or be used as a step to help get into the bed. Yes, there's even a handle. Ford who? The step itself can support up to 375 pounds, 75 pounds more than Ford's similar tailgate step. This tailgate really is unique to the Sierra and is standard on SLT and Denali models. That said, the power-operated tailgate from the Silverado won't be coming to the GMC. Chevy gets its own exclusive, too. The Sierra's other big exclusive is the carbon-fiber reinforced plastic bed box. CFRP replaces steel inside the bed though not on the fenders. The bed uses four pieces; one for the bottom, one in the back and two along the sides. This isn't a CFRP. There is no steel hiding underneath these panels. Just take a peek underneath. The bed is a composite that uses 1-inch carbon-fiber threads, not a weave. Sheets of CFRP are molded and quenched — a process where the plastic coagulates and solidifies, locking in the carbon fiber — in just 60 seconds. That allows GMC's supplier to crank out these much more quickly. The finish looks like black fiberglass, though an engineer said that this wasn't the final production version. The final model will have different textures in order to improve grip and keep things from sliding around. GMC is touting the material's dent and corrosion resistance, though it remains to be seen how well it holds up to cracking. A video at the reveal showed people going after it with hammers and cinder blocks, but in-person demonstrations weren't available.

Ranking full-size pickup trucks by the size of their discounts

Each and every month, full-size pickup trucks dominate the new-car sales reports in America. It's been that way for years — the Ford F-Series has been America's best-selling vehicle for 38 consecutive years — and it's not going to change any time soon. With that in mind, we've compiled this list of discounts on brand-new full-size pickup trucks using data provided by Truecar, including their average retail prices, average transaction prices and discounts in dollars and percentage off list price. We've also created a visualization of the best deals Americans are scoring on the three best-selling models in America. If you're looking for the absolute biggest discount you can find on a new truck, look no further than your nearest Ram dealership, then scour the lot for a leftover 2019 1500 model. Buyers are averaging nearly 13% off the cost of the 2019 Ram, paying an average transaction cost of $41,667. That's $6,071 off the average retail price, which equals the best truck deal in October. The 2020 edition isn't discounted nearly as far, averaging $2,852 off for an average transaction price of $48,904. The next best deal is on the 2019 Ford F-150; its average transaction price of $43,064 equals $3,843 off its sticker price. The 2020 F-150's $2,810 discount means buyers are paying around $47,300. They should know, though, that a brand-new model is coming for 2021, so we'd expect bigger discounts on remaining 2020 inventory in the coming months. Moving to General Motors, the best deal you'll find is on leftover 2019 Chevy Silverado 1500s, which are selling for an average of $47,043. That's $2,852 off the sticker price. Interestingly, 2020 Silverados are seeing slightly lower transaction prices at $46,009, but with a smaller average discount of $1,693. The 2020 GMC Sierra is mechanically similar to the Chevy, but aimed at buyers who want a bit more luxury. That's reflected in the 2020 Sierra 1500's average transaction price of $54,491, which is $2,131 off its sticker.
