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.

Optimus Prime and Bumblebee head for auction

This month at the Barrett-Jackson auction in Scottsdale, AZ, the customized 1992 Peterbilt 379 of Optimus Prime from the Transformers series and director Michael Bay's own 1967 Chevrolet Camaro SS for Bumblebee will cross the block. The company will sell both with no reserve, and they'll come with letters of authenticity. This specific Bumblebee is the mean-looking restomod from Transformers: Age of Extinction, the fourth installment in the franchise, and Bay apparently liked it enough to hang onto the aggressive coupe after filming. He even autographed the car for this sale. The Camaro would make a great star in a Hollywood chase scene with its LS3 V8, six-speed manual gearbox, Wilwood brakes, and custom suspension. Bumblebee also wears a menacing satin black body with yellow accents and custom carbon fiber fender flares. Optimus Prime's Peterbilt appeared on-screen in the first three Transformers films, the auction house's spokesperson Aaron Cook told Autoblog. An Autobot emblem sits proudly on top of the grille, and the truck wears a flame paintjob. Barrett-Jackson's description says that the semi is fully functioning but no longer street legal and is now for display only. It would likely be the ultimate piece in anyone's Transformers collection.

Sunday Drive: Trucks and SUVs of all shapes and sizes

The American automotive marketplace is dominated by trucks and SUVs, and so was the last week of coverage on Autoblog. By far, the most popular story of the week was our First Drive of the 2018 Lincoln Navigator. It may look like an old-school lumberer, but in reality Lincoln's flagship is a thoroughly modern, turbocharged-V6-powered, three-row, luxury people mover. The Jeep Wrangler is the world's most recognizable vehicle. So it's no surprise that the next version looks a whole heck of a lot like the last one, and the one before. It's all in the details, which is why we were so excited when Jeep decided to unleash a trio of images showing both two- and four-door Wranglers for us to dissect ahead of the SUV's official debut at the L.A. Auto Show later this year. Past that, spy photos of the next Chevy Silverado and Ram 1500 were predictably popular. See both of those below, and the cap it all off, check out the entire week's worth of SEMA coverage – including the bonkers Hennessey VelociRaptor 6x6 – in our mega image gallery at the bottom of this post. Enjoy! As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Lincoln Navigator First Drive | From black sheep to flagship 2018 Jeep Wrangler revealed: First photos released before L.A.
