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.

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.

2021 GMC Sierra adds towing tech, new HD Black Diamond Edition

Trailer towing is the focus of several new technologies coming to the 2021 GMC Sierra pickup, with the new features available both on the Sierra 1500 and the Sierra HD. The 2021 Sierra also sees expanded availability of GMC's MultiPro tailgate, a price cut for the available 3.0-liter Duramax turbodiesel six, and a new Black Diamond Edition of the Sierra HD. Pickup truck makers are engaged in a trailering-technology arms race. Already, the GMC Sierra offers its ProGrade Trailering package that features a "Transparent Trailer" virtual camera view and a Rear Trailer View that uses an auxiliary camera mounted on the back of the trailer. To that, GMC is adding a Trailer Length Indicator that can alert drivers of another vehicle in the adjoining lane during a signaled lane-change. A new Jack-Knife Alert warns the driver if the front of the trailer approaches the rear of the tow vehicle. The warning appears in the center screen and can also trigger a seat vibration. The previous Rear Side View split-screen now also works when reversing and adjusts for the angle of the trailer. The Cargo Bed View now includes a zoom feature and hitch guidance for connecting gooseneck trailers. Finally, the previous Rear Trailer View adds a trailer-angle indicator and dynamic guidelines. In other equipment news, the six-position MultiPro tailgate is newly available on the Sierra 1500 SEL and Elevation trims and standard on the Sierra HD SLE. The fancy Sierra HD Denali adds Surround Vision and Bed View cameras to the standard-equipment list. Standard and optional engine choices for the Sierra are unchanged for 2021, but the price of the optional 3.0-liter turbodiesel engine in the Sierra 1500 is reduced by $1,500. For 2021, on models where the 5.3-liter V8 is standard (SLT, AT4, and Denali), the upcharge will be $995. For the SLE and Elevation, where the 2.7-liter V6 is standard, the cost to upgrade to the diesel is now $2,390, again a decrease of $1,500. Lastly, the Sierra HD adds a Denali Black Diamond Edition. It includes 20-inch gloss-black wheels, power-retractable side steps, premium audio by Kicker, an Auxiliary Trailer Camera, trailer tire-pressure monitor sensors, and premium floor mats with removable carpet inserts. It comes in any color you want so long as it's Ebony Twilight Metallic. The Black Diamond Edition is pictured above. Related Video:
