Drill a hole in the cap and a hole near the top, seal them and insert preferred tubing. Then you can unscrew the cap fill with desired fluid cap back off and apply about 8 to 10 psi regulated is easiest and it will push the fluid right out which ever hose your not using to pressure the container with. Stick that end in the fill and your good to go. Whole setup costs less than 12 bucks and will have your manual transmission filled in less than a min. This does of course assume you have access to a compressor or pump.
