Can somebody explain how to takeoff with de-rated thrust 55C and have VNAV automatically engage CLB thrust. I get a constant TOGA thrust and my speeds go through the roof. Yes, manually setting speed and using VS works fine. But I want to use TOGA, LNAV and VNAV. Still do not see how. Yes, I tried 1.2. No real change in TOGA/CLB thrust autotransition.

Guys, no one appears to have answered this question. Comments about methods of uninstall, regedit etc are pointless when you have done it correctly a number of times and deviate from the question asked.  I'm interested in BrzI's question as well. There seems little info on how to use the FMC to derate TO performance, particularly to select and arm the options; the use of TOGA and the transition to climb.
Thanks
