Hello,<br />I recently fixed my trim problem by changing an O ring on the manual release vavle. This resulted in me loseing a lot of fluid. When I tested the trim out the motor would raise up, but not go back down. i figured this was just low fluid because it does this automatically. So i've been topping the fluid up over and over, running air bubbles out of the system. I was wondering if not having enough fluid would be the cause of this problem and also if it is how long I have to run the air bubbles out before this problem will be fixed.<br />Thanks
