The tranny does need to learn when you install a new tune. Drive it normal for about 15 miles varying the throttle. No full throttle runs right away. Whos tune did you upload?

Just to add a note here..
When installing custom tunes you should not need to return to stock first. The custom tune will over-write the old program entirely.

When installing a pre-loaded tune, you should always start from a stock tune.

On both situations, you should install the tune and drive it easy with slower gradual tip ins on the pedal to let the trans adapt.
