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.

2013 GMC Acadia Denali

Refreshed, Not Refreshing
I'm probably ill-suited to accurately and fairly take the full measure of a vehicle like the 2013 GMC Acadia Denali. This is a machine conjured around the express notion of corralling and then herding a brood of rafter-swinging hatchlings to and fro in relative comfort, and with no such passel of wee Bowmans to call my own, it's difficult to give this rig a fair shake. While I can certainly weigh cargo capacity, legroom and fuel economy stats with the best of them, I'd be lying to your face if I said the word "crossover" didn't urge some uncontrollable Pavlovian recoil from the murky recesses of my frame. To put it simply, I just can't stand the damn things.
As a rule, the segment is built on a bed of compromise. Manufacturers love nothing more than to spin up a tired yarn about the virtues of this particular neck of the market. We're told the crossbreeds deliver all the ride quality, driving dynamics and fuel economy of a car married with the seating position, capability and interior volume of the SUV set. That all sounds as swell as a sunset, but as the 2013 Acadia Denali so artfully illustrates, the advertising on the box is rarely congruous with the prize inside. Even with an imaginary squad of younglings at my heels, the refreshed luxury crossover doesn't quite manage to scratch the promised itches.

GMC considers adding more vehicles to broaden product line

GMC is considering expanding its product portfolio in the next 10 years to allow it to reach more potential buyers and grow sales, a top executive said Monday. The small and midsize sport-utility-vehicle segments are two possibilities, said Duncan Aldred, GMC sales and marketing vice president. He also said GMC won't make a car, preferring to reinforce its reputation as a maker of trucks and SUVs. "There's plenty of opportunities even if we define ourselves as a we do as a truck and crossover brand," he said. He wouldn't comment on the possibility of adding a Jeep Wrangler-fighter, though rumors have swirled for months that GMC is considering a product to compete with the iconic off-roader. "I can't confirm that ... everything's on the table," he said. He also said that it's possible GMC could get a unique set of underpinnings – all of its vehicles share platforms that are also used by Chevrolet – but it's not needed to differentiate his brand. "I'm very happy sharing underpinnings and everything else," he said. "All of the good-performing automakers do that." Speaking to journalists at a roundtable at General Motors headquarters in Detroit, Aldred said GMC received an investment from GM that is double what the brand has historically spent to fund its growth plans. Advertising spending alone will increase 50 percent this year compared with 2014. The brand rolled out a new ad campaign on Monday, called "Precision," that will underscore attention-to-detail and the premium features of GMC vehicles. Two of the commercials have a sporting theme, and the third focuses on modern menswear. GMC called it a "contemporary interpretation" of the brand's traditional positioning, and it will also continue to use its long-running "Professional Grade" tagline. The premium positioning of the ads come as buyers are increasingly outfitting their trucks as near-luxury vehicles. The percentage of buyers opting for the top-end Denali trim has increased from 17 percent in the middle of 2014 to 21 percent now. The goal is to get Denali to make up 25 percent of GMC sales by the end of 2017, Aldred said. Spurred by the higher Denali take-rate, the brand's transaction prices leapt by $3,000 last year. "It's [Denali] really kind of this jewel in the crown," Aldred said. GMC sales increased 11.3 percent in 2014 to 501,853 units, making it GM's-second-best-selling brand behind Chevrolet.
