Thanks for the info. My top doesn't always go down, but of course today when I took it to the dealership it worked. Where do I find the conv. motor? (I've only had the car a couple of months.) 98' Mustang

Not sure if your motor is the same as mine ('71 Cutlass), but mine says the same thing: fill with Type A transmission fluid. Mine has a rubber plug on one end of the motor. All I have to do is pull that out (carefully so as not to tear it) and funnel in the fluid. After you fill it (until it runs out the hole) I would recommend running the top up and down a few times, then refill it. This should bleed out any air in the hydraulic lines. It's that easy for me...hopefully yours is the same. Oh, and I believe that Type A transmission fluid is equivalent to today's Dexron III or MERCON. Good luck!

Filling the reservoir until fluid runs out is a disaster waiting to happen. The reservoir should be filled with the convertible top in the lowered position and the final level should be approximately 1/4 inch below the bottom of the fill hole. Here's why: The reservoir is a buffer. There is always fluid in the upper and lower portions of the lift cylinders. When the cylinder rod is fully retracted, the reservoir is at it's highest level. This is due to the cylinder rod displacing some of the fluid in the cylinder. When the rod is extended (top raised) the entire bottom of the cylinder fills and reservoir level wiil be at it's lowest point. Imagine what happens if you fill the reservoir while in this position, and especially if you fill it until fluid leaks out. Hmmm, lower the top, level rises until there is no more room in the reservoir (or air volume is compressed until pressure blows the oring seals out). At this point, pressure in the reservoir will be greater than 300psi. (these pumps dead head at about 300-350psi) This means the main oring seal will blow out and the fluid in the reservoir will now be in your trunk. No one wants that.

If you look behind the back seat , look at the hydrolic motor there is a rubber plug that you take out and you use a sqeeze bottle to put the fluid in. hope this helps.

to check fluid level raise the top and remove rear seat cushion put some rags below the filler plug remove plug fluid level should be level with bottom edge of hole do not operate top with plug removed if fluid is low check system for leaks and add fluid REPLACE plug

If one wants to use convertible top fluid on a 1992 Lebaron convertible, one should first put the fluid on a rag and begin to wipe down the top. It is important that one spread the fluid evenly on the top.

all of the components for the top, including a plug in the side of the motor to fill with fluid from are under the back seat area. Refill for fluid is dex trans fluid.

Unlatch the latches at the top of the window, then press the convertible top button down. this button is located near the armrest. If this does not work you must aquire a new convertible top motor. from the trunk, remove hyd. fluid from the conv. top pump, operate top by hand. worked for me for years

in the trunk remove battery cover. the top pump motor is on the top-remove the plug in the resovoir and fill with green dragons blood.

The motor is under the vinyl fabric that the convertible top drops into when it's down. You can access it from the trunk. There is a rubber cork in the reservoir where the fluid goes. You pull out the cork with a pliers and add the fluid up to the hole, until a little runs out. I use a turkey basting syringe. Put the cork back in and run the motor both ways a couple of times. This gets the air out of the system. Pull out the cork and add enough fluid to bring the level close to the hole. then insert the cork. If there's no leak this should do the trick.

It is both, an electric motor runs a hydraulic pump.
