2017 GMC Sierra 1500: Surge, Hesitation, Chuggle, Misfire, Feeling wit


Recommended Posts

Sorry so late with reply, So they changed the torque converter and I have drove my truck for about 4 days now. Chuggle is still present in the ~25 / 35 MPH range but not nearly as bad. I would guess my truck is 80% better than before the work. It still has a slight hesitation (not nearly as bad as previous) but still there. They have corrected most of the problem, but I am going back and have them continue troubleshooting or following the service bulletin. I will keep posting the results as they happen. I really love this truck and want it to be fixed! I have also attached a document of the service.
