While operating vehicle on highway, I experience a shake/shudder when at speeds of 50 mph and higher. Vehicle was taken to dealer stated that the torque converter did shudder. Dealer changed transmission fluid and I was advised to drive for 200 miles to see if problem was corrected. Shudder still remains and now the vibration is constant at 70 mph. I called dealer again who said that it was probably a tire balance issue. I argued with them and stated I had no such issue before first bringing vehicle in. Dealer is setting up appointment for me to take in again. Vibrations have literally caused my 6 yr old daughter to vomit on 3 different occasions when in the vehicle. She has only been in vehicle 5 or 6 times. Vehicle feels unsafe at highway speeds. I have read many forums online stating this issue is on many vehicles gm has made. I am curious as to when gm will be mandated to take corrective action or buy the vehicles back from the owners.

8 speed transmission is dangerous. Under light throttle, the vehicle will make a loud popping noise and lurch forwrward. Like stopping at a stop light, driving through a drive-thru. My truck will shake violentlly. . Dealer says its the transmission. When I try to enter my garage the truck will sort of jump forward. Delear says its torque converter sutter. Transmission has been worked on 3 time. It seems to get worse. Delears says the 8 speed transmission has many issues but gm does not have a fix. These 8 speed transmissions will end up killing folk. . This stuff happens on a daily basis.

Vehicle is shuddering and shacking at speeds any where from 35 to 55 mph. I took it to the dealership and was told it's a known torque converter issue.
