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 GMC Hummer EV could get a rival from China's Dongfeng

The popularity of GMC's Hummer EV hasn't gone unnoticed in China. State-owned carmaker Dongfeng is reportedly planning to launch an electric version of the M50 Warrior, a Hummer-like off-roader, that will inaugurate a new sub-brand dedicated to battery-powered trucks. Without citing sources, website Car News China wrote that the division will be called M, a letter that stands for something completely different if the cars that you're into come from Munich. Executives are initially planning three models called M18-1, M18-2, and M18-3, respectively. The M18-1 will reach the market first, and it's described as an electrified M50 Warrior (pictured) with seating for six. Dongfeng will build the M18-1 on a new architecture called MORV that was developed in-house. The powertrain will develop up to 1,072 horsepower, which is 72 horses more than the most powerful version of the Hummer EV, yet the zero-to-60-mph time will check in at under 5 seconds, which is roughly 2 seconds more than the GMC. It will offer around 310 miles of range thanks to a 140-kilowatt-hour battery. Another interesting point is that the M18-1 will supposedly be much lighter than the Hummer EV — it will even weigh less than the gasoline-powered M50 Warrior that it's based on. It will tip the scale at around 6,900 pounds and stretch about 205 inches long, compared to 9,046 pounds and 217 inches for the Hummer. Of course, these numbers are purely hypothetical until the truck starts rolling off the assembly line. Speaking of, production is tentatively scheduled to start in 2023 in a factory that's currently being built in China. Dongfeng expects to sell approximately 4,160 units per month, though nothing suggests that the M18-1 will venture onto the GMC Hummer EV's home turf.
