Ok, took the cover off the motor, removed the plastic cover inside covering all solenoids. The trim solenoid is clicking and seems to be working. I trimmed the motor all the way up, engaged the lock position and let it back down on the lock. I removed the screw to the fill tube on the left side and I can't see a drop of fluid. So next step is to add fluid. What type of fluid do I use? I don't know when fluid was last added, the plastic screw that I removed was pretty tight and didn't have a single marking on it like it hadn't ever been removed before. I'm pretty sure that fluid may be my problem, hot weather and low fluid can't be a good mix. So I'll pick some up tomorrow and pour in. Last question for tonight: How far do I fill it?
