Torque converter shudder and noise (definitely and issue related transmission). Around 1,500 RPM the vehicle starts to experience the shudder, shaking, and noise. Additionally there is a feeling of a surge in power, like if the vehicle shifts to an upper gear un intentionally, the vehicle launches forward occasionally (lurching forward). There is absolutely no issue while the vehicle idles, not at low or high RPM. The issue only occurs while the vehicle is in motion and at around 1,500 RPM. Using a V4 to V8 delete (Range Technology RA003B AFM/DFM Disabler) helps the issue significantly but it's still an issue. If that disabler is removed the issue is extremely pronounced. I purchased this vehicle as a used vehicle. I wouldn't have purchased the vehicle if I had the slightest idea of such a major issue with the vehicle.

The transmission flutters when shifting on my 2015 Corvette. A potential catastrophic failure could cause a fire from transmission fluid hitting the hot exhaust. General Motors is aware of the issue and has issued a TSB. I believe a potential fire and or collision exists if transmission fluid spills on the pavement. transmission fluid could cause spinouts of vehicles on road behind a car with failure. My vehicle has been experiencing this for the last couple months. Two different dealerships offer to change the fluid in the transmission but no guarantee the internal components have sustained damage.

When the vehicle is in motion, at a constant highway speed, 40 to 70 MPH,any acceleration or deceleration, causes the car to vibrate for several seconds. I feel this is a safety issue because, at times, during the 'shudder' event, the car will lunge forward.gm has diagnosed the problem as 'shudder' and has issued a service bulletin. The fix they recommend is a complete transmission flush and fill with an upgraded transmission fluid. I am assuming the oem fluid is defective. This condition is not an isolated event. It happens almost ever time speed is accelerated or decelerated. My vehicle only had 5600 miles.

Slow down shift. When you hit the accelerator while the car is down shifting, there is a 2 second delay. I came off express way and turned on to road then hit the gas to merge into a lane when there was a 2 second delay. Very dangerous. How do I fix problem? Why is chevrolet not fixing problem.

Tsb 18-na-355 - vehicle is experiencing a shake and/or shudder during light throttle acceleration between 25 and 80 MPH (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. The experience is similar to driving over rumble strips or a concrete road surface with rough expansion joints. Took to dealership to repair, but they are stating the warranty ended in january and requiring me to pay for the fix. Will join the class action lawsuit.

The vehicle is equipped with an 8l90 automatic transmission. It has a severe shudder problem when cruising down the road at 50 to 70 MPH. Can get almost undrivable. Also will not upshift after a performance downshift. Dealer flushed transmission per gm bulletin but problem is still there. Looks like almost all of gm 8 speed transmissions have this problem circa 2015-2016.

I've almost been hit twice pulling into traffic on a city street with this car. Shifting when the transmission is cold into 2nd gear from 1st gear is near impossible and appears to be a known problem based on my internet search. Several times I've pulled into traffic and couldn't shift it into 2nd gear. By then the car is slowing down with traffic bearing down on it and you have to slow down even more to go back to 1st gear. The local dealership says this is normal but I disagree because it's a safety issue. I have to rev the engine higher and go directly into third gear to protect my life.
