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.

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.

I have a 2015 corvette stingray with 35k miles. The vehicle has been to the dealership 2 times already once at 11k miles and second time at 22k miles where the car should shudder while cruising at low speeds. Also in the morning during a cold start when I would shift the car from park into reverse then the car would do a hard shift. Twice the dealership changed the fluid in the transmission and rebuilt the entire transmission since the car was under warranty. But my car's extended warranty expired on 03/01/20, in 06/01/20 the issue came back. Now gm is refusing to take responsibility to fix the vehicle. When refueling, tank filler pipe accepts fuel only very slowly. Several different gas station pumps were tried, all kept clicking off every 3 seconds (as if tank was full). Tank was empty to take in several more gallons of fuel.

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 had my vehicle serviced at dan vaden chevrolet in savannah, ga on 16 oct 2017 at (12,200 miles). My main concern was a shudder and jerky motion the car starts demonstrating while in motion, accompanied by fluctuating engine rpms. After researching on the internet there are 1000's of issues with these torque converters and who knows what accidents these failures have caused. There should be a total recall on these transmissions. A service department technician test drove my vehicle and confirmed and documented my concerns and stated it was okay to drive ? I am scheduling another service at (13000 miles). A search of the internet will fill you full of facts on these failures. Problems with the torque converters with these high end vehicles are well on the way to become another corvette issue of epidemic proportions. Please assist.

Please see snip from http://corvettec7fiasco.blogspot.com/2016/02/thousands-of-2015-and-2016-chevrolet.html thousands of 2015 and 2016 chevrolet corvette c7 stingray and c7 z06 with defective 8l90 8-speed automatic transmission, with no help from general motors for the owners back in 2014, this blog predicted a variety of problems related to then upcoming 8l90 transmission, one of those sounding on paper ideas, as long as the execution delivers on the promises. So far, the variety of problems related to the new +general motors 8l90 eight speed automatic transmission was already mind boggling: from expected overheating issues, failing flex plates, variety of leaks and software related issues, all the way to right down scary cases of transmission voluntarily "inspiring" new corvettes to rev up and attempt to take off. However, what was missing were the problems with the torque converter. Apparently, this is no longer the case and in fact, the torque converted problems are well on the way to become another corvette issue of epidemic proportions, further eroding already weak faith the hardcore corvette buyers may have in +general motors and the ever popular +tadge juechter . As expected, the undersized and high spinning torque converter issues manifest themselves in a shudder and jerky motion the car starts demonstrating, accompanied by fluctuating engine rpms. However, here lies the big problem: the same symptoms can be easily associated with the ever popular afm forcing the newest corvette into 4 cylinder mode. There are 1000's of issues with these torque converters and who knows what accidents these failures have caused. My car is in the shop for 1 week for the repair, thank god it was covered by warranty.. There should be a total recall on these transmissions.. A search of the internet will fill you full of facts on these failures.
