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.

Weekly Recap: Auto execs face life in prison for recall delays under proposed legislation

The stiff punishments are part of broader transportation legislation, but clearly McCaskill has automakers in her sights.
Missouri Senator Claire McCaskill threw down the gauntlet this week, proposing a bill that could send auto executives to prison for life if they were found to have delayed a recall. She also wants to eliminate the limit for fines for auto safety violations, which are currently capped at $35 million.

The 2021 F-150 elevates Ford's bed game

The new 2021 Ford F-150 is ushering in a new era of pickup capability, but there's more to it than the introduction of the PowerBoost hybrid. While that new powertrain is certainly the truck's headlining element, the supporting electrical architecture enables a level of utility that hasn't been offered in past consumer half-tons. The true party trick is Ford's new "Pro Power Onboard" feature, which is essentially a built-in generator that provides juice for the 2021 F-150's rather robust in-bed power station. This system is available even on gasoline-engine models, but its utility is maximized with the electrified powertrain. ICE models equipped with the option max out at 2.0 kilowatts, while the PowerBoost hybrid can be had with either a 2.4- or a whopping 7.2-kilowatt inverter.  The idea here is that the F-150 can essentially stand in for a high-output portable generator. In a worksite example provided by Ford, a PowerBoost model with the 7.2-kW upgrade and a single tank of fuel could provide 32 hours of power for an 1,800-watt compound miter saw, a 1,000W circular saw, a 1,200W battery charger, a 1,200W hammer drill, and a 1,000W air compressor with hundreds of watts to spare for lighting and other accessories. But even without the Pro Power Onboard option, Ford's new bed setup enables more versatility than in previous models. The new Tailgate Work Surface option adds a flat work area with integrated rulers, recesses for pencils or small tools, and even a stand for a personal device.  Ford is neither the first to offer an auxiliary power outlet in a half-ton pickup bed, nor was Ford the first to introduce a more feature-rich tailgate. GMC's MultiPro tailgate was a major innovation on that front, and while it is geared mostly toward improving the cargo utility of the bed, it can also be customized with 12-volt power and even an accessory speaker system. The Ram 1500 is also offered with both a multi-function tailgate and AC power in the bed, though the latter option is limited to models with the RamBox cargo package.  As half-ton pickups approach levels of towing and hauling capability that begin to blur lines with heavy-duty offerings, it's clear that automakers are looking for ways to differentiate themselves without stepping on their own bigger trucks' toes. These new bed and tailgate innovations may yet be the tip of the iceberg when it comes to full-size pickup versatility. Related Video:
