I am new to the group, and indeed to MOCpages, but I have some advice:
Having no ball joints or ratchet joints, I would recommend using technic, and using lots of worm gears to govern shoulder, hip and spinal transformation hinges.
For knees and elbows I use axles that slide through cross-pin holes like pistons, providing high friction. Modern technic contains 5.5 measure-long dark grey axles with a flange at 1 measure which are very good for this purpose.
Non mobile parts that need to move during the transformation I lock using pegs and rivets.
And, as a general rule, build a basic robot that becomes a sturdy chassis before adorning with the head, the body panels, and weapons.
