About a year ago, I started getting a slight shudder in my transmission so I took it to the dealer for repair. They couldn't get it to shudder. Several times I'll be driving down the road at or around 45mph and the truck will start shuddering so bad I feel like I have to pull off the road. Every time I take it to the dealer for repair I end up losing my truck for a day and they tell me they can find anything wrong even though this is a known issue and there is a TSB out to fix the issue.
The truck's drivetrain/transmission constantly shakes, shutters while driving. It happens periodically throughout the rpm ranges.
The transmission in my truck shakes, shimmies, vibrates, shutters when driving and shakes, shimmies vibrates even at idle. I took the truck to the dealership and they removed all of the transmission fluid and replaced with new fluid as per Chevrolet corporate mandate. The truck remains in shaking, shimmies, shutters and vibrating.
