If your trying to change diagonals, I go with the "one, two" count. You count "one, two, one, two..." In rhythm with your posting. It's a solid, steady beat. Then when you go to change diagonals, you sit for a "one, two" and come back up again on one. I've had a couple students who had to do the counting out loud to really get the rhythm. If you sit for one, you get the wrong diagonal, same thing if you sit for three beats.
If your just trying to sit the trot period, I suggest getting your feet out of the stirrups. Let your leg be long, and bring your butt deep into the saddle. I tell riders to shift their weight to the back two seat bones, loosen the lower back and think of an "up, back" motion with their hips. It works best with no stirrups, using your thigh to grip and your seat to balance. When you can comfortably sit the trot without stirrups, try picking them back up while your sitting the trot. Keep your back loose, and your hips in sync with the horse, just ad that bend to your leg, and get your foot loosely in the stirrups.
But I'm mean, I make my riders do sitting/posting transitions with no stirrups forever before I give them their stirrups back for the sitting trot...
