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.

Woodward Dream Cruise Photo Gallery | Classics and American muscle

The 2022 running of the Woodward Dream Cruise just went down, and we were there from morning to evening drinking in the sweet sights and pre-emissions exhaust fumes. Yes, it’s a little smelly on Woodward Ave. this time of year. Just like always, the Dream Cruise invites all comers to cruise their machines on Woodward from Ferndale, MI to Pontiac, MI. Everybody is invited, but the original intent of the Dream Cruise was to highlight classic American muscle cars. YouÂ’ll see plenty of those in our mega gallery above, but weÂ’ve sprinkled it with a bunch of other vehicle types, such as modern muscle and other intriguing American vehicles. Similar to years past, though, sometimes the classics arenÂ’t the most entertaining thing to look at on Woodward. ThatÂ’s why weÂ’ll have other mega galleries coming soon, highlighting the weird cars and (great) dogs of the Cruise, all the imports and exotics you can imagine and a special one for all the trucks of Woodward — perhaps even more so than in years past, the truck population on Dream Cruise day was quite high. Click through above to see all the classics you wouldÂ’ve seen had you been roadside on the day of the cruise. And if you missed this yearÂ’s event, make sure you check out what happens next year. You wonÂ’t be alone, as itÂ’s estimated that over 1 million people attend the Dream Cruise to either watch from the side of the road or to sit in the most glorious traffic jam in the world.

2014 Chevrolet Malibu gets more torque, more room and inspiration from the Impala

The 2014 Chevrolet Malibu, having stared at the Impala across the showroom floor for a year, gets nips and tucks all over inspired by its larger brother. The 2.5-liter four-cylinder in the base car will get a stop-start system and 23 city miles per gallon, 35 highway, each number representing a one-mpg improvement over the 2013 car. Output is 196 horsepower and 186 pound-feet of torque.
Opt for the 2.0-liter turbo and, while power holds steady at 259 hp, torque goes up by 14 percent to a striking 295 lb-ft (a figure Chevy calls best in the class). The final details include newly programmed transmission shift points and faster shifts, for better engaging and enjoying the added power.
Looks-wise, the grille's been reshaped to be more in line with the new Chevrolet look, a narrower upper grille hovering over a larger lower grille.
