Yeahh, I know I'm not following the Boeing procedures by the book but I'm payed for this (in a box of course).
This ship is so smart that I could not beleive that Boeing left an open door into the protection modes.
According the AMM the systems monitors the TLA and if they are blocked for more than 2 seconds they go into HOLD. (aka pilot holds them or something mechanical like too much friction). That's how you can have the HOLD in FLCH climb.
