6r80 problems

[TxS197]

Hey guys my 2014 GTCS It flares going into 4th gear on an easy acceleration
Some times it does it on WOT as well
It has a Circle D 3c in it and only has 16k miles
Fluid and filter changed and the pan was clean
Heard these have issues with valve bodies
Can anyone relate to this situation?
Thanks

Take a datalog and see if it's actually flaring, or if it's commanding first gear for a brief moment instead of fourth. There's a TSB for this related to the leadframe.
