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.
Transmission won't shift into gear after shifter is moved with engine running. Dashboard indicator shows selected gears, but transmission doesn't engage.
