The transmission shifting has a lot to do with the tuning and mechanical limitations of the transmission fluid passages.

Usually, when more power is put through the transmission, the tuning will compensate by increasing fluid pressure during the shift. This increased pressure will fill the clutch housings/servo bore/etc. faster and with more force. If the transmission pressure increases begin to show less of an effect as they are raised, then mechanical fluid control becomes the issue.

As long as you don't get a long, drawn out slide into a gear, you'll be fine. The low power shifts that kick don't hurt the transmission but they can be annoying.

Most any competent tuner can fix that right up for you.
