When I drive the EB 5.0L the box feels nice & tough while it changes gear on light footed accelaration (hard shifts)& when accelarating hard foot buried into the carpet the box has smooth shifts unless I put the shift kit on.
Now with the EF I6 it changes quite diffrent to the EB like when tromping the EF she holds the gears longer & shifts it harder into gear where as light footed driving she is smooth?

well the eb v8 will have more torque so thats why it shifts earlyer than the ef. not 100% sure but i think the ef does have some adaption values to, if ur heavy on the throttle the ecu knows that u want to drive fast so changes gears faaster, which makes it a little a***, if its smooth when light throttle sounds like everything is fine.
