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.

Buy the Denali Ultimate, and the interior is just as good as the competition. If you're not going all out on luxury features, though, at least get the diesel. It's the smoothest operating diesel engine out there, and it's also efficient. This is one great truck when you set it up in the ideal configurations." Senior Editor James Riswick — "The GMC Sierra Denali interior has gone from "They just didn't try" to "They tried harder than everyone else." The Denali Ultimate's design, detailing and materials are particularly impressive. If you want a luxury truck, this delivers."

eBay Find of the Day: 1976 GMC Motorhome is a jolly green giant

If you have a need to relive the 1970s, then here is the vehicle for you. This groovy blast from the past is a 1976 GMC Motorhome currently for auction in Florida on eBay Motors, and it is one green machine - just not in the modern sense.
The seller claims that this beast has had just two owners and has covered a mere 61,308 miles in its decades on the road. It's reportedly never been restored or repainted and comes with all of the necessary books and manuals. A 7.5-liter (455-cubic-inch) Oldsmobile V8 with a three-speed Turbo-Hydramatic automatic transmission powering the front wheels propels this far-out RV, and the double set of rear wheels out back use a self-leveling air suspension to provide a cushy ride.
The purported low miles and good condition really make this GMC a stand out, though. The exterior combination of lime stripes and beige with just a touch of green is like nothing else on the road today. Plus, the polished bumpers and wheels make it all pop. Inside, it's even better with monochromatic green upholstery and shag carpet. It features everything you'd ever need on a long trip, including a bathroom, kitchenette and lots of seating. The only hint of modernization is an HD TV next to the stove, but its size is a perfect fit for the hole there.
