Convertible pump fluid?

[PBLA]

Unfortunately I don't have a owner's manual, and this sight doesn't allow the word "convertible" in a search! What type of fluid do I add to the convertible pump/motor? Is there a convertible section on this site? Should the top be up or down when accessing the pump? Thanks

LRS has a kit for the convertible top motor that comes w/Royal Purple ATF. Most will say that Dexron III ATF will do. My '85 leaked the hyudraulic fluid and it was clear though but maybe the previous owner put in brake fluid (not recommended for our year).

As far as up or down -- it will use less fluid to retract the piston (lower the top) since the rod takes up space so check the level w/the top down. When the top is up the piston/rod is extended which takes more fluid so the level in the reservoir will be lower. I hear if you top off the reservoir when the top is up it will blow seals when the top is lowered since there isn't room for all the fluid that the rod is displacing.
