I have replaced the lift cylinders and lines on my top. What type of fluid should I use and what is the best process for filling the system? The motor is hard to get to so I was thinking I would pull it out and reconnect the ground to make filling easier. I would fill the reservoir then run the motor to get the fluid in the lines and to the cylinders then refill the cylinders. I would continue this process until the system was full. Is there a better way to do this?

Pulling it out is a really bad idea. No way to get air out of the system. Remove the rear seat, the fill plug will be on the tank end of the pump. Fill it with Type F trans fluid, and cycle it. Check the level, fill again if needed. Repeat as necessary.
I have done this and the top does not move. I have put about a quart in. I can see the fluid moving the lines but there are still large air bubbles. It seems like fluid moves back into the reservoir when I stop running the system.
Should the top be up or down when filling the system? I have top down.
How does this system work? Does the fluid run from the rear hose to the upper fittings on the cylinders? Does this then push the cylinder out and lift the top?
Still working on this top. I cycle the fluid up and down but it gets to a point where the fluid stops moving. The pitch of the motor also changes. There is definitely enough fluid in the reservoir because every time I open the screw fluid leaks out. Could the motor be bad and need to be replaced? At what point should the top start to move?
I cant run the car because there is a transmission leak along with a list of other problems. I was working the top while waiting for other parts. I am going to put a battery charger on it and see what that does.
Would the car running give the motor any more power or just help save the battery?
I charged the battery and rechecked the ground and the motor works. However the top is still not moving. Again, I run the top motor for a while and then the fluid stops moving. Could this be an electrical issue and draining the battery because the car is not running?
