Narrative:

We were cleared to enter holding at jenno intersection as published on the lvz 5 arrival to jfk at FL250. After entering holding; we received a clearance limit to lendy and to descend to FL230. We inadvertently climbed to FL254. The following happened at the time: TCAS TA; call from ATC; and I saw as decreasing while in a climb. The autoplt and autothrottles were disengaged and expedited descent to FL230.
