Vibrates

[captdbg]

Hi have a 17’ GMC Yukon Denali with 18000 miles On a trip last week it started to vibrate and feel like your running over small speed bumps every 15 seconds between speeds of 35 and 75 mph Tires look ok gonna get them rebalance in couple days Was wondering if anyone experienced this Thank You

Lots have experienced this. It's an issue with the torque converter. I believe the first crack at it is to replace the fluid and update the TCM programming. If the problem persists, they replace the torque converter.

. I believe it's more of a hit-and-miss type deal my Yukon Denali 2016 is currently in a dealership right now they replaced the fluid and reprogram the trans for the same problem I literally pick it up this afternoon I'll write back with my experience if it worked

It’s under warranty take to the dealer. I believe even the tire balance is at this point.

Adam, According to the TSB a new Torque Converter would be next step and finally a new tranny.

Rotors need turned or replaced. Really should get new pads at the same time.
