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 Chevy Silverado priced from *$24,585, V8 gets better economy than Ford EcoBoost V6

Chevrolet has thrown down the next hand in the pickup truck poker wars and revealed at least a couple of potential aces - depending on which numbers matter most to you. The 2014 2014 Silverado 1500 with its 5.3-liter EcoTec3 V8 gets 335 horsepower and 383 pound-feet of torque, is mated to a six-speed automatic, can tow 11,500 pounds with the optional Max Trailer Package and costs the same as the outgoing Silverado, $24,585 (*including $995 destination fee). Chevy says the Silverado also stands atop the fuel economy charts when comparing any competitor with a V8 engine - and some competitors with V6 engines. The two-wheel drive model returns 16 miles per gallon city, 23 mpg highway, 19 mpg combined in two-wheel drive guise and 16 mpg city, 22 mpg highway and 18 mpg combined as a four-wheel drive.
For context around those numbers, the most fuel efficient V8-powered 2013 Ford F-150 pickups lose about two mpg in every metric compared to the Silverado, the 3.5-liter V6 EcoBoost returning 16 city, 18 highway and 22 combined in two-wheel drive. However, that EcoBoost does have 365 hp and 420 lb-ft of torque. You can get a Ram 1500 with a 3.6-liter V6 that gets 25 mpg highway, but it has 305 hp and 269 lb-ft of torque. The 2013 Ram with the 5.7-liter Hemi V8 and its 395 hp and 407 lb-ft drops one mpg in every category to the Silverado. Its tow rating is 200 pounds beyond its nearest competitor, the F-150 with the Max Trailer Tow Package.
Elsewhere, the new Silverado gets a quieter cab with a redesigned interior, a new bed with improved load-management possibilities, disc brakes all around, tweaked steering and suspension, along with free standard scheduled maintenance for two years or 24,000 miles.

2016 Chevrolet Camaro starts at $26,695

Parking the new 2016 Chevrolet Camaro in your driveway will cost $26,695, including the $995 destination charge. That's a cut from $27,000 for the same trim on a 2015 Camaro. If you prefer a V8 under the hood, then the base 1SS goes for $37,295, compared to $34,500 for that model currently. The 2016 Camaro is offered as a coupe and convertible in four trim levels: 1LT, 2LT, 1SS, and 2SS. The LT is available with a 2.0-liter turbocharged four-cylinder with 275 horsepower and 295 pound-feet of torque or a 3.6-liter V6 with 335 hp and 284 lb-ft. The SS gets a 6.2-liter V8 with 455 hp and 455 lb-ft. The first examples arrive before the end of the year, but droptops and the turbo engine don't materialize until the first quarter of 2016. Base models come with tech like Chevy's MyLink infotainment system with Apple CarPlay, a rearview camera, automatic climate control, and multiple driving modes. The RS Package adds to the style with 20-inch wheels, HID headlights, LED taillights, a different grille insert, and rear spoiler. Opting for the SS brings a more aggressive exterior look, plus performance upgrades like Brembo brakes, differential and transmission coolers, and a limited slip differential on those with a manual gearbox. Upgrading to the 2SS adds amenities like heated and ventilated front seats, wireless phone charging, a Bose stereo, rear cross-traffic alert, and Side Blind Zone Alert with Lane Change Alert. Options like a Magnetic Ride Control suspension and dual-mode exhaust offer additional sportiness. Reading about the 2016 Camaro is nice, but Chevy now has a visualizer for the pony car. It's not quite a full configurator but lets you check out different colors, wheels, and stripes to imagine your future purchase. Enjoy finding just the right combo.
