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.

Use this PowerPoint when convincing your spouse to let you buy a Corvette

When you are not the one in charge of the purse strings, creativity is a must when trying to get the string-holder to bankroll that next shiny object you just can't live without.
When I was a kid, I decided that life wasn't worth living if it weren't in pursuit of owning a GMC Typhoon. My 12-year-old self crafted a fiscal strategy that, when combined with my offer of a 49-percent share of ownership in the car in return for my parents' contribution of 80-percent of the purchase price, would see me behind the wheel of a Typhoon by the time I hit college. They walked away from the negotiating table and, the economic climate of the 8th grade being what it was at the time, another partner wasn't found before the Typhoon was discontinued.
Roy El-Rayes, however, has succeeded where 12-year-old me failed, and he did it by using the sort of professionalism that only a PowerPoint presentation can provide, along with some humor and bold-faced flattery.

Recharge Wrap-up: 'Racing Extinction' Tesla, Wards praises 3 hybrids

The makers of Racing Extinction used a tricked out Tesla Model S for their movie. The artists and activists used the electric car as a platform to project images from nature in various cities to raise awareness about imperiled wildlife. In addition to a the high-powered projector, the Model S features a electroluminescent paint job that emits light to mimic creatures found in the wild, such as bioluminescent sea life. It also has a thermal imaging camera in the front of the car with a filter to view CO2 emissions. Check it out in the video above, and read more at Ecomento. WardsAuto has named the 2016 Hyundai Sonata Plug-In Hybrid's powertrain to its list of 10 Best Engines. As the first plug-in hybrid to make the list, WardsAuto World Editor-in-Chief Drew Winter praises Hyundai engineers for their "impeccable job blending fuel efficiency with refinement and daily usability." Wards notes the car's smooth transitions between electric and hybrid modes, and a well-connected six-speed automatic transmission. Other electrified vehicles to make the list are the 2016 Chevrolet Volt and 2016 Toyota Prius. Read more from Hyundai, at Green Car Reports. FEV's plug-in hybrid battery pack has gone into vehicle series production. The 10-kWh battery pack, developed by the German development services provider, offers an all-electric range of about 30 miles. FEV says its battery management algorithms are just as important as choosing the right battery hardware. "The core system for the battery development is our own mature battery management system (BMS), now in its third generation, that together with optimized algorithms allows a very reliable and stable control of the battery," says FEV's Dr. Michael Stapelbroek. Read more at Green Car Congress, or in the press release from FEV below. Hybrid Vehicle Goes Into Series Production FEV development competence consists of batteries, controls, as well as complete drive systems FEV has demonstrated competence in the development of alternative drive concepts for almost twenty years. Most recently, yet another plug-in hybrid vehicle has gone into series production with technology provided by the Aachen-based developer. In addition to using an innovative transmission concept which is based on a FEV patent, FEV also developed the battery technology of the plug-in hybrid vehicle to series production readiness.
