My truck has just over 500 miles on it and between the speeds of 35-55mph the truck will get a shudder that I can feel in the steering wheel. Almost feels like driving on a mild set of rumble strips on the side of the highway….If that makes sense, and this only last for about 3-5 seconds at a time but this occurs over and over. When I’m on the freeway the truck is fine and drives great this is only at lower speeds and its almost like the engine is out of sync with the transmission.
Please provide feedback of similar issues/instances or solutions. Thanks

I work for a Cadillac dealership in the service department. We have had complaints of that very same thing. We have actually replaced some of the torque converters in the transmission. In other cases we have also replaced the complete transmission. Hope this helps.

Thank you, I’ll be taking my vehicle in for service very soon and hopefully this resolves the issue.

My Denali with the 6.2 is doing the same thing at the same speeds. At first I thought it was the lane departure warning vibrating the seat, but I can perfectly reproduce the condition. I have just under 500 miles on mine.

I first noticed mine around 400 miles, and now I notice it daily as I’m aware of the issue. I called the dealer today and talked to a service representative and he told me the transmission is “Learning” and to wait after a 1000 miles to bring it in if its still occurring. I’m almost 100% sure the issue is the torque convertor after doing some research on the issue. GM released a service announcement of some sort on the issue. Search “#PIP5337C: Shake or Shudder Between 30 and 65mph” for 2015-2016 models, there is hardly anything on 2017 models but after I read this document my truck has all these symptoms. I’m going to wait until the 1000 mile mark before I call the dealership and take it in.

I work at a GM dealership and we have also had a couple of these vehicle’s with rear diff issues causing the “shake”

I bought it brand new Dec 2015 (2015 High Country 4×4, 6.2ltr V-8) with the new eight-speed Hydra-Matic 8L90 transmission. So I’ve had it a year now and have put 19k + miles it. I noticed about a month ago when the engine was cold and I went from park to drive it felt as if I was parked on a hill and the trans was in a bind, taken 1-2 seconds before roughly engaging in gear. Then it started doing it more often even when the transmission fluid temp was above 130. Well last week it began to shudder almost like driving over road strips before a stop sign. I also noticed that if I had it on cruise control between 40-60mph the tachometer would rev up every time it shuttered/vibrated. It took it back to the dealership as it is still under warranty and had the mechanic ride with me so he could see for himself what my Chevrolet was doing. He knew immediately as to what he thought was causing the vibration…torque converter he says! So as of right now it is in the shop to replace the torque converter with an upgraded one per this bulletin 15389 which provides a service procedure to reprogram the transmission control module (TCM) on certain 2015 model year Cadillac Escalade, Escalade ESV, Chevrolet Silverado, GMC Sierra, Yukon Denali and Yukon Denali XL vehicles equipped with an 8L90 8-Speed (M5U) transmission and 6.2L (L86) engine. These vehicles may have a condition in which transmission calibration allows a higher than target energy input to the torque converter clutch (TCC) under certain conditions. This may lead to faster than expected torque converter clutch material wear, and a shudder feeling.

I purchased a new 2016 Silverado 1500 WT, standard cab “black out” edition truck December 28th, 2016 from Holz Chevrolet. I noticed the “vibration shudder” at speeds of 30-60 mph when the motor is under low load and can duplicate the condition. I will be taking it back to the dealership ASAP and real happy to have to do so with 1,300 miles.

So any other action done after talking with the dealer? I doubt the idea about the “Learning stage”

My 2017 Silverado High Country 6.2/8-speed is currently at the dealer for the fourth time since I bought it last December with this exact shudder problem. At steady speeds the tachometer constantly goes up and down by about 200RPM as the shudder comes through the steering wheel. GM told the service department to have me continue to drive it and see if anything changes. Not an option…

I’m taking my 2015 LTZ 6.2 in tomorrow for a torque converter replacement. I was told it locks up and rumble strips is the common feeling. When it does it just watch the RPM jump up. I was told that was an indicator. I’m sure the GM dealer will attempt to suck me dry as usual but not this time.
