Alex, so i understand that having Lnav and Vnav engaged thrust should automatically change to CLB regime, but i cannot see such action, so if i do not change it manually then plane climbs like a rocket. I always take off with lnav and vnav engaged.

Correct.

My procedure is engage VNAV at the acceleration altitude (800AFE usually, sometimes 1000AFE, sometimes 1500AFE). and CLB always comes on automatically. Can you take a video of your example and show us how yours is working? Mine works as expected.
