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.

Camaro driver clocked at 171 miles per hour

Chevy's 2016 Camaro SS is a fantastic piece of automotive engineering. It is also, apparently, very, very fast. This latter fact was perfectly illustrated when, on April 8, a Camaro SS driver was nailed in Two Harbors, Minnesota for doing 171 mph. According to WFAA, the unnamed speed demon was flying down Highway 61 near Two Harbors when Hermantown, MN Deputy Police Chief Shawn Padden clocked him at an eye-watering 171 mph. He then recorded the speeder at 168 and 141. At the time, Deputy Chief Padden was working with Minnesota State Patrol on an anti-DWI program called "Toward Zero Deaths". Padden, who was interviewed by the Duluth News Tribune, said he was surprised at the driver's sheer speed. "When he went by me, it was a blur," Padden told the News. "You get used to seeing people going 65 or 70 and what that looks like. But I've never seen anything like this. It's like a rocket on wheels." Fadden chased the Camaro down eventually, but it took some doing. To catch the Camaro, he pushed his Dodge Charger Pursuit to 135 mph just to get into range so the Camaro could see his emergency lights. The speeding driver was ticketed for careless driving, but may lose his license due to a Minnesota law that gives courts the option of revoking licenses for drivers caught doing more than 100 mph.
