09 Yukon 6L80 TC shudder every 20k miles

Update, the trans shop didn't seem like it was a big deal and they said they put a whole new transmission and torque converter in where last times they rebuilt my original one and put new torque converters in. He said for every 20 6l80 they work on, one wants to act like mine. Just won't get right. So hopefully won't be back to see I'm 20k miles this time!

Good luck with the new trans!
