The transition period is relatively short and you are moving fairly slow (less than 80 kts or so?) when they deploy. I don't think deploying them significantly changes lift or drag, but it does introduce a "slat" on the leading edge to help keep the airflow stuck to the wing in extremely high angle of attack situations.
