No problem, its literally walking up a couple flights of stairs/escalators going through a turnstile then walking down a couple flights of stairs/escalators. I've made transfers with only 2 minutes in between. A helpful tip would be to keep your ticket out with the black magnetic strip facing up and on the right(direction right) portion of the ticket. That is the position in which you must enter it into the turnstile. Having it ready will save you precious seconds
