Usually (in my limited pax experience) they do this in level flight, not when climbing.
I've had that experience before. Yes they do level out before "cooling the gear" and not while climbing. From what I heard from others, the pilots will ask to maintain a certain altitude, lower the gear until the temp issue is resolved, and then ask to continue climbing to normal cruising altitude.
