“Please note GM PIP5146A...Chatter or Bind Feel on turns... AKA transmission shudder. According to Cadillac dealer in Durham, NC. The car needs it's rear differential replaced; 90,000 miles.. That is happening now. Ally, the extended warranty company, sent a technician to inspect the part. I don't know if the original part is still available. I 1st noticed the problem in Fall 2019. Shop invoice, 62,187miles, reflects differential fluid & filter change which temporarily, partially mitigated the problem for a few years. It never disappeared. I am not sure what the worse case safety scenario is. I never let it get that far.”
