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.

2014 Chevrolet Silverado tows in new configurator, microsite

Judging by your continued enthusiastic response to configurator notices, dear reader, you enjoy speccing out new cars as much as we do. Better still, there tends to be even more ways to personalize, configure and bloat theoretical MSRPs on full-size trucks as there are with more ordinary passenger cars. In addition to trim level, engine and transmission choices, truck buyers usually have to specify items like cab configuration, bed length, number of driven axles, tow packages, gear ratios and all sorts of bits and bobs.
That's why we're pleased to see the DIY specification utility for the 2014 Chevrolet Silverado come alive so soon after this week's Detroit Auto Show debut. While the configurator lacks pricing (General Motors hasn't announced numbers yet) and full options, you can still spec out your half-ton rig, and even print it out or email it to your friends. Beyond the configurator, the new model-specific site is pretty cool, too, with various videos and closer looks at the truck's new features.
The new Chevrolet pickup range won't be on dealer lots until sometime this summer, so whether you're a building contractor, an avid sportsman or just a guy or gal that loves full-size trucks, you might want to check out the link below to keep your appetite whetted. If you're more of a Sierra fan, well, it looks like you're going to have to wait a while - GMC hasn't updated its site yet.

Chevy already offering discounts on 2016 Volt

The second-generation Chevrolet Volt has a longer range than the first-generation version, but General Motors doesn't appear to want to take any chances of the extended-range plug-in not being well-received. The US automaker is already offering some cash incentives to make sure the 2016 Volt moves briskly. In fact, GM is offering incentives worth up to $1,000 through November 2 in some states, Green Car Reports says, citing CarsDirect. Most of the country won't get the second-generation Volt until next year, so GM is looking to keep all potential buyers satisfied. That means perks for folks in California, Connecticut, Massachusetts, Maryland, Maine, New Jersey, New York, Oregon, Rhode Island and Vermont - the states where the new 2016 Volt will go on sale first. Buyers can pick up another $500 in incentives by luring a non GM-vehicle owner into buying a new Volt. And then, of course, there's the $7,500 federal-government perk, in addition to any goodies your particular state will throw in via tax breaks. For everyone else, GM is offering as much as $2,500 off the 2015 model year Volt. The 2016 Volt has an MSRP of $33,995, which is actually slightly less than the $34,170 sticker price on the 2015 model. The new version has a 53-mile all-electric range, 15 miles longer than the first-generation Volt. With a lower price and more electric miles, GM hopes to reverse falling Volt sales. Through September, GM sold 9,264 Volts, down 36 percent from a year earlier. You can read our First Drive impressions of the 2016 Volt here.
