Hi, I was told by the service manger at my dealer that the torque converter needs flushed and driven 3 times and there’s a COMPUTER UPDATE that needs to be done to rectify the problem! If that doesn’t solve the problem then replace the torque converter.
Hi, I have a2016 GMC Sierra Denali, when driving at 35 45 65 70 mph there’s a short vibration in the the driveline. The dealer said it’s probably the torc converter. Anybody have this same problem? What did you do to correct the problem?
