Just viewed on "Gearz" program on SPEED. Believe it or not he was using an "ENEMA BAG"!! Straight from the local drug store they come with a thin enough tube to fit the trans fill-tube and an On/Off valve in-line. Fill the tube with the exact amount of your choice of fluids, hang it, insert the tube and let her rip!
No muss no fuss, no spills. Last tip was to be sure to keep it in the garage!!
