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.

2020 GMC Acadia AT4 priced just a little more than the SLT trim

Cars Direct has seen the order guide pricing the 2020 Acadia AT4 at $42,495 after destination; that means a $41,300 MSRP plus $1,195 for shipping and handling. GMC has left a lot of pricing room between the rugged, all-wheel drive AT4 and the dressed-up, top-shelf Acadia Denali with AWD, the latter costing $49,495, a $7,000 difference. The spread's blown out some by what appears to be an $800 increase for the 2020 Acadia Denali with all-wheel drive. The 2019 model costs $48,695. On the other hand, it looks like the 200 Acadia SLT trim has gone down in price. Cars Direct says that model will run $41,995, which is $300 less than the 2019 version that goes for $42,295 after destination. The new price leaves a $500 gap between the SLT-1 model with all-wheel drive and the AT4 trim, a figure that's a no-brainer to justify for any buyers trying to get a more butch curb appeal.     The Acadia AT4 package comes standard with all-wheel drive and the 3.6-liter V6 with 310 horsepower and 271 pound-feet of torque, puts black chrome on the grille, and nabs a set of exclusive 17-inch wheels on all-terrain tires. The other two engines in the lineup are a new turbocharged 2.0-liter four-cylinder with 230 horsepower and 258 pound-feet of torque, and cylinder deactivation. That motor will be the standard kit on the SLT and Denali trim levels, supplanting the 3.6-liter that's standard on the 2019 models. The entry-level engine carries over, a naturally aspirated 2.5-liter four-cylinder making 193 horsepower and 188 pound-feet of torque.

GM pickup truck plant in Flint to add 1,000 assembly workers

FLINT, Mich. — General Motors said Tuesday it will add 1,000 workers to build new heavy-duty pickup trucks at its plant in Flint, Michigan, and will give priority to GM workers who were laid off elsewhere. The announcement comes the day after GM said it was starting to hand pink slips to about 4,000 salaried workers in the latest round of a restructuring announced in late November that will ultimately shrink its white-collar workforce in North America by 15 percent out of 54,000. GM has come under fire from U.S. President Donald Trump and Midwestern lawmakers for its plans to stop production at five North American factories and cut up to 15,000 jobs in all. The automaker has said it is trying to find new jobs for 1,500 U.S. hourly workers at the affected plants. Flint's truck plant could be a haven for many of these employees. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday will celebrate the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. Elsewhere in the company on Monday, two people briefed on the cuts in the white-collar salaried workforce said GM is cutting hundreds of jobs at its information technology centers in Texas, Georgia, Arizona and Michigan and more than 1,000 jobs at its Warren, Michigan Tech Center. GM is filing new required mass layoff notices with state agencies and disclosed the cuts to lawmakers. The largest U.S. automaker announced in November it would cut a total of about 15,000 jobs and end production at five North American plants. The cuts include eliminating about 8,000 salaried workers, or about 15 percent. GM cut about 1,500 contract workers in December and said 2,300 salaried workers accepted buyouts, officials said. "These actions are necessary to secure the future of the company, including preserving thousands of jobs in the U.S. and globally. We are taking action now while the overall economy and job market are strong, increasing the ability of impacted employees to continue to advance in their careers, should they choose to do so," GM spokesman Pat Morrissey said, adding the bulk of the cuts should be completed in the next two weeks. Morrissey said GM would provide salaried workers with severance packages and job placement services.
