The motor trims up and down 100% normal while idling around up to around 50-60% throttle. Once I'm up at full cruise speed or so(20-25mph) the motor will only trim up and will not trim down. It also makes a pretty terrible noise. Once you slow back down to ~10-15mph you can trim down normally again.

So in short:
Motor trims up normally in all conditions
Motor trims down only when not under too heavy of a load and normal with less than 50% throttle or so.

Where should I start?

Sound like the motor trims down under its own weight and cannot do that with water pressure keeping it up at speed. Only a guess here but i would think lack of fluid/air in system, try bleeding it and filling it with correct fluid.
