Just thinking of transmission oil change, man. trans. totally ignorant of same, remove drain plug, plus filler plug, also breather. Drain oil, when drained, replace drain plug. Pressure feed replacement amount of oil through filler plug hole, take it easy with pressure flow. When required amount of oil replaced, remove pressure fitting, replace Fill plug, then Breather. Take your time, if you are working too hard, you are working too hard. Of Pressure Feeding? perhaps one could use a Mechanics Professional Cooks Baster, (think Turkey) found at Auto Dept. Wallys, otherwise if you are Boilermaker, Hydraulic person, or anyone familiar with pressure devices, a simple arrangement of available parts could be assembled. Have Fun. Next issue, have figured out how to completely drain and refill an automatic trans. simple and easy with utmost efficiently. Keep in Mind, Liquids tend to reach the lowest level, air the highest if allowed to do so, and don't ever Ignore Gravity, it's claimed, it's always present, cheap, and made available to everyone.
