Complaints

I first experienced a shuddering that could make the beverage in my cup sitting in the cup holder on the right side of the transmission shifting lever form foam. Oh dang, but road repairs in some parts of Texas appear to be irregularly semi-scheduled in a non reoccurring manner on a random basis. My weekly trips along the same road were the only time I was noticing the shudder, so I just chalked it up to bumpy secondary country roads.. And then it happened!

Cruising down the interstate not on cruise control doing around 73 MPH on a flat straight section, I lightly accelerated to kick it up a bit to set the cruise control.. Foam forming in my beverage may have occurred, but I was too preoccupied attempting to see how many pine logs I had just run over to cause the worse jerking experienced yet. I once had a utility trailer built without any suspension using springs, or shocks.. Seeing it jump off the ground and come down with a bang was an experience, and that's what it felt like this time.

The shuddering was soon occurring often and the speed didn't seem to be the major factor, Just trying to lightly accelerate while cruising along in a higher gear seemed to be the cause  I searched the internet to see if this had been a reported problem or one subject to a Chevrolet recall when I happened upon this site. I have thoroughly enjoyed reading of the same problem occurring with others and was stimulated to finally contact my Chevy Dealer yesterday with only 2700 miles on my truck!

I made a trip to visit the Service Manager personally and was glad that I did. He was very knowledgeable of these situations and explained a sequential approach to effect a proper solution.. His plan of attack sounds very similar to what I have read aout so far.–Flush the transmission, check fluid flows, and probably replace the torque converter. If it checks out OK there, I'll drive it for a few hundred miles to see if it was “fixed” or not. If NOT, a prescription for surgery and a transmission replacement may be necessitated

Shudder/Vibration easily felt in steering column about a week ago, has gotten worse and more often.  The tech who signed me in mentioned it may be the transmission fluid they'd used originally, (or the torque converter, which it ended up being). My concern is wondering what they used, why that could cause shudder, vibration, any “long term effects” for the transmission?
