  1. So I’ve searched all over and can’t seem to get a straight answer to what I’m experiencing. So I have a Black Bear Tuned 03 GMC Sierra 1500HD with the 4L80E 4 Speed Automatic transmission with the ability to Manually shift 1-2-3. My understanding is that when I Manually shift it down into 1st gear it’s suppose to lock it into 1st gear so it revs up way higher and engine brakes to slow down but does not shift until I manually shift up to 2 or 3 or put it back in Drive. Well when I lock it into 1st gear, the revs are much higher but it still automatically shifts to 2nd gear once I get close to 25-30mph even though I have 1st gear selected. Is Manual shift lock not working for me? Has anyone else experienced this? I just don’t get the point of manual shifting if it’s still gonna shift up automatically anyway Thanks for any input!
  2. John Goreham Contributing Writer, GM-Trucks.com 1-29-2019 Chevrolet has added the new 10-speed automatic transmission to its hottest Camaro, the ZL1 1LE. GM says that experienced racers can shave seconds off lap times on longer high-speed circuits with the new automatic by comparison to the 6-Speed manual. Although our staff has not tested this generation of the Camaro ZL1, we have tracked the prior generation with the manual. It was for sure the limiting factor in quicker times for this writer. By comparison, we drove the Lexus RC F with its race-tuned 8-speed auto and were amazed at how well modern track-tuned automatic transmissions can match the gears to the particular needs of the vehicle at any given point on the track. These modern automatics rev-match downshifts and wil keep the vehicle at the perfect point in the RPM range for maximum thrust in all scenarios. “This transmission is optimized for speed,” said Camaro Chief Engineer Mark Dickens. “With unique Track Mode calibrations and 10 gears, you are always in the perfect gear when rolling on or off the throttle. You may not be a professional race car driver, but now you can shift like one.” Steve Majoros, director of Chevrolet passenger car and crossover marketing, expanded on that, saying, “Adding an automatic transmission is another example of the Camaro portfolio delivering what customers want. This ultimate 1LE is another appealing option that is true to its racing heritage.” The new 10-speed becomes available on the Camaro ZL1 1LE in February. What say you GM-Trucks faithful? Would you opt for the automatic in a car you planned to track, or would you prefer the 6-speed stick?
  3. John Goreham Contributing Writer, GM-Trucks.com 11-13-2018 A new study conducted by the Insurance Institue For Highway Safety has proven that GM's automatic emergency braking (AEB) is working and that it can have a huge impact on the number of crashes it is designed to prevent. Study author Jessica Cicchino, IIHS vice president for research, looked at 2013-15 Buick, Cadillac, Chevrolet and GMC brand vehicles. GM provided VIN numbers and whether or not the vehicles were equipped with the optional AEB system. The analysis of real-world crash data revealed that the vehicles equipped with both warning and AEB reduced accidents by 43%. The crashes were the type the system is best at preventing, front to rear crashes from behind. What is most significant is that the accidents reported by police to involve injuries were reduced by 64%. Accidents were also reduced by the GM system that only offered a driver a warning, but by a much lower percentage. "The evidence has been mounting that front crash prevention works, and it works even better when it doesn't solely rely on a response from the driver," says Jessica Cicchino, IIHS vice president for research and author of both studies. GM is one of the last manufacturers who is launching new models without making the technology standard. The Silverado, for example, offers AEB, but only on some trims, and it is optional on others. Every manufacturer has pledged to make the technology standard on all mainstream models and all trims by 2022. This new study jives with a prior IIHS study that looked at Volvo vehicles.
  4. Our experience with the all new Camaro has been outstandingly positive. Just last fall, GM-Trucks.com drove a 2016 Camaro SS over 1,600 miles from Minneapolis to Salt Lake City in an epic road trip. The SS turned out to be a strikingly composed vehicle. In our time with the last generation Camaro ZL1, we were equally impressed but the vehicle's extra weight made it harder to control on the track. This generation is over 200-lbs lighter. The all new ZL1 will dial this lighter generation pony car up to the proverbial "11". Specialized bodywork on the ZL1 improve aerodynamics and cooling. A larger front splitter, unique rockers, larger rear spoiler and wide front fenders are designed to keep the Camaro ZL1 stable at high speeds. A special "flow-tie" Chevrolet bowtie insignia is open to allow more airflow to the engine compartment. Inside the ZL1 has standard Recaro front seats, a suede flat-bottom steering wheel, and suede shift knob. Chevrolet's performance data recorder (PDR) is also available. The ZL1 also comes with unique 20-inch forged aluminum wheels with exclusive Goodyear Eagle F1 Supercar tires [285/30ZR20 Front / 305/30ZR20 Rear]. Those huge tires will get help stopping with massive 15.35 inch rotors squeezed by six-piston Brembo brakes up front. 11-heat exchangers throughout the Camaro ZL1 make this four-person car track ready straight from the dealership. Pricing and availability have yet to be announced.
