Narrative:
Manually leveled aircraft at 10000 ft engaged autoplt and aircraft started to climb. At 10100 ft disconnected autoplt to return to 10000 ft. Aircraft altitude never got to more than 10150 ft, but got a call from departure to maintain 10000 ft that they showed us climbing through 10300 ft and that call was received as we were re-leveling at 10000 ft. Local altimeter from ATIS was 30.19. Autoplt worked normally for remainder of flight and was not written up.
