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.

Junkyard Gem: 2003 Chevrolet Tracker

When General Motors created the Geo brand to sell vehicles designed and — in some cases — built by Japanese partners, the first four models were introduced for the 1989 model year: the Metro (Suzuki Cultus), Prizm (Toyota Sprinter), Spectrum (Isuzu Gemini) and Tracker (Suzuki Sidekick). Geo got the axe in 1997, with the Metro, Prizm and Tracker becoming Chevrolets. Of those, the Tracker survived the longest, with U.S.-market sales continuing into 2004. Here's an example of a very late Tracker, found in a North Carolina car graveyard recently. The 1989-1997 first-generation Trackers were based on the Suzuki Sidekick, while the 1998-2004 Trackers had the Suzuki Vitaras (not to be confused with the much grander Grand Vitaras) as their siblings. Production of these trucks for the South American market (as the Chevrolet Vitara) continued in Ecuador all the way through 2014. The Tracker name has also gone onto some versions of the Chevrolet Trax around the world. This one is a base four-door hard top/rear-wheel-drive model, which had an MSRP of $17,330. That's about $29,789 in 2024 dollars. You'll find one in every car. You'll see. The engine is a Suzuki 2.0-liter straight-four rated at 127 horsepower and 134 pound-feet. A five-speed manual was base equipment, but very few American vehicle shoppers wanted three pedals by the middle 2000s. This truck has the Aisin four-speed automatic. We like it loud. It appears that someone associated with this truck graduated from Julius L. Chambers High School last year. In the United States, the Tracker was replaced by the Saturn Vue. If Tracker can handle (unspecified Middle Eastern country), it can survive the jungle back home. Siempre contigo.
