Narrative:

On flight en route from atl to ord, the left #2 leading edge flap did not retract from flaps 5 degrees to 2 degrees on climb out. Had amber light on flap indicator and amber light on so panel. This was at about 1000 ft MSL and we went through the abnormal checklist for 'leading edge flap light after retraction checklist.' nothing worked. So went to visually check #2 leading edge flap. It was extended. At this time, the captain transferred control of aircraft to me, the first officer. We were passing 10000 ft, cleared to 18000 ft. Captain called maintenance and flight control and confirmed we could not continue to our destination of ord. Captain was not listening to center frequency. He told me to get clearance for atl. During this time we had been cleared to FL230. As we were passing 17500 I requested lower and direct atl. Center came back with cleared to 16000 ft, left turn, direct rome. We had been flying at 215 KTS due to flap problem. I started a descent and a left turn. As power was reduced, we had an automatic-pack trip condition. So turned off packs so he could reset system. Flight attendant knocked on door and cabin altitude started coming up. Cabin pressure came up to 15000 ft. Center gave me a new frequency and no reply. Went to emergency frequency 121.5 and no reply, found new frequency about 30 seconds later. Altitude had descended to 15500 as I was debating an emergency descent because of loss of pressurization. The packs were turned on and pressurization came back. Center cleared us to 10000 ft, rome arrival to atl. Made uneventful overweight landing without declaring an emergency. Flaps were cycled, and operated normally. No emergency was ever declared, although center was advised we were experiencing difficulties.
