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.

Chevy murders out Trax crossover with new Midnight Edition

Leaning towards a new Chevy Trax, but think it needs a little bit more attitude? Chevy has you covered with the release of the new Midnight Edition. It's based on the Bowtie brand's smallest crossover, but injects some extra style with its murdered-out treatment. The new Chevy Trax Midnight Edition is based on the top LTZ trim, and upgrades with black wheels, bezels, molding, door handles, and more. Inside, the cabin is adorned with gray-accented seats and gray-piped floor mats. It isn't a huge transformation, but may be just the dose of attitude that Chevy's little crossover needs. Otherwise it's the same Trax introduced a year ago, and comes equipped with a 1.4-liter turbo four good for 138 horsepower and 148 pound-feet of torque. It's available in either front- or all-wheel drive, and will return a claimed 34 miles per gallon on the highway in the former setup. The Midnight package adds an extra $500 to the $26,125 base MSRP on a new Trax LTZ.

Based on the LTZ trim, the Midnight Edition features black wheels, bezels, beltline molding and door handles, along with a black rear license plate applique. Inside, the seats are trimmed with gray accents and the floor mats feature gray piping. "Introduced just a year ago, the Trax has quickly become an important vehicle for Chevrolet, bringing in new, younger and more female buyers to the brand," said Betsy Flegg, senior marketing manager, Chevrolet Crossovers. "The small SUV segment is the fastest growing in the industry and models such as the new Trax Midnight Edition provides customers an expressive option." Trax sales were 57,707 for the first 11 months of 2015, placing it second in the segment, with almost 20-percent market share. Chevrolet crossover sales were up 35 percent for the same period. Fusing small-car agility and utility convenience of an SUV, Trax offers up to 48.4 cubic feet of cargo space. A 1.4L turbocharged engine offers the efficiency of a small displacement engine – an EPA-estimated 34 mpg highway (FWD models) – with the power of a larger engine on-demand. Connectivity features include an available 4G LTE Wi-Fi hotspot.
