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.

These are the five most ridiculous attacks on the Chevy Volt [w/videos]

It's been a long, strange trip for the Chevy Volt from the time when the now-odd-looking concept version (above) was introduced at the 2007 Detroit Auto Show to today. And now, General Motors announced that the second-generation Chevy Volt will make an appearance at the 2015 Detroit show in January. This debut represents a victory for GM with what has easily become the most politicized car of the 21st Century. There are plenty of reasons for someone to criticize the Volt, but what's amazing is just how much anti-Volt energy has been spent not on things like the styling or how the EREV setup is not as efficient as a pure-EV powertrain. As we wait for more official information on the new Volt, we thought it would be fun to go back and look at some of the most wildly incorrect reporting and strangest attacks on the Volt from the archives. There is so much good stuff out there, it was hard to pare the list down, but these are our five favorites. Amazingly, they're not all clips from Fox News. Check 'em out below. 5. GM Is Going To Stop Making The Chevy Volt In The US Do you remember when GM was about to move Volt production to China? Well, yeah, this was reported back in early 2012 when a GM executive mentioned that the automaker would get benefits of building the Volt in the places where it sells them. This was spun into a story of GM taking Obama bailout money and then running to China. The Blaze was not happy: "Given the fact that Federal government helped itself to millions and millions of taxpayer dollars under the pretense that it was going to combat high unemployment by creating 'green jobs,' it would seem that moving research and development (and possibly manufacturing) overseas is slightly, well, counterproductive." Well, of course, that never happened. There's no way to say that GM will never build a version of the Volt in China, but the news we hear rumors of these days is that GM is going to move production of more Volt parts (specifically, the motors) to Michigan from overseas. 4. The Chevy Volt Is A Fire Trap There has never been a Volt that just spontaneously lit up while driving down the road. Yes, there were Volts that caught on fire. Yes, that's a scary thing. But there has never been a Volt that just spontaneously lit up while driving down the road. These were crashed test vehicles with destroyed batteries and plugged-in vehicles that were not the cause.
