777 A/P disconnects around 7000 and 30000 FT

[asanal 32]

This  is ongoing problem with my 777.

After loading 777 and  proper trim settings. When Plane reaches  around 7000ft A/P suddenly  dis connects and  starts to nose dive. Same situations happens  around 30, 000 Ft.

I am suspicion with Trim Setting. I don't think . during the   climb,  trim is not collaborating  with airplane C/G  and causing  onbalance  pressure buildings  on A/P, then  sudden disconnects.

Is it possible? I am out of ideas.

Likely a controller spike, a trim axis not being set to zero, or a trim axis on a piece of hardware that you don't realize has a trim axis assigned to it.

Try taking off, putting the plane on AP, and then unplugging your hardware. If the issue goes away, then the cause is your hardware.
