I have a 2013 Sierra with 129k and it’s doing the exact thing. I also had the undoings replaced and the driveshaft rebalanced. I did read it’s called torque converter shudder. If you’ve never changed the fluid, I’d recommend you do it. I actually found a product called Dr Tranny instant torque converter shudder eliminator.. it sells at Oreilly Auto parts. It’s about 11.00 . Y put it in the tranny fill port.. squeeze the whole thing with engine at idle. Should help it. mom having my truck diagnosed next week.. I’ll let you know what they find out.

The fuse you want to pull is under the hood,It is fuse number 47,It is marked "INFOTMNT",It is a 15amp fuse. Make sure the green light on the right side of the mirror is out (It should be Black)

OnStar is located on my truck 2013 under the radio. Near the floor. There is a panel there. Remove it and the OnStar and Bluetooth module is attached there

Guys, need your help here. I replaced the factory radio with a Pioneer AVH-5700BHS , and it sounds great. Although i used a GM3A-RSTX interface the OnStar sounds horrible. Excessively distorted. i cant even connect to Bluetooth without it sounding bad. I replaced the interface but i still have the same issue. I replaced the radio back and it works fine. Anyways, has anyone had this problem? How did you fix it? Also second question, using factory XM radio on the Pioneer, the connection is different, anyone run into an interface that will work?

Try a brass hammer if you have one. They don’t spark. In the Navy since I was on a Minesweeper, we used brass tools for the specific reason of them sparking. Just an idea

Hello, hope by now you have figured it out. Have you tried using the stock ring? is their anyway you have open the bracket holding the ring down? Once you open it enough you can secure it by hammering it back down

All- New on here, but i am having light vibrations on my truck when going about 40 Miles. I replaced the u joints, did the differential service and still getting the vibration. At first, I felt it mildly, mostly when turning on a left curve. Now im feeling it whilst driving and cruising on the road. I sometimes feel it on the gas pedal, and sometimes on the steering wheel. I had the truck checked out this weekend for the suspension( struts, and shocks) and they said it was good. Any ideas?
