overdrive gear ATM - A340E A340F

? torque converter have any bit to do with this overdrive gears not shifting back to 3rd gear at low rpms with a small amount of throttle

 
this is what controls the downshift from D to 3?
or those solenoid things
 
if it has to do with ECU then that likely means it needs a special tool scanner programmer to adjust it?

so far i have not encountered this on the interWebs with someone else having this very issue with this type transmission engine combo
