2016 Torque Converter Bad Again?

[jdabest]

2016 Yukon had trans/tc replaced already, trans flushed with updated fluid, Getting the rumble strip and vibrations again. ANY good shops that can be recommended in the ATLANTA Area. Don't want to go down this rabbit hole again but it seems to be that way
