Narrative:

During climb out of dtw, I was cleared to 5000. At 4000' the first officer called 1000' to go. At 4700' the controller gave us traffic at 10 O'clock at 7000 descending to 6000. At this time the first officer had to talk to company so I took the radio. A 200' to go call was not made by the first officer due to his being distracted by company. I answered the traffic call and then looked at the altimeter. We were 5400' climbing 2000 FPM. I corrected and the controller called us to inform us to descend to and maintain 5000'. Another point to mention is that this was the 1ST day I was flying after a cold snap and there was a great increase in climb performance.
