I got a 1996 Acura Integra GS-R 5 speed. I'm trying to change the transmission fluid, but i'm not sure how to do this. I got the service manual and it says for me to check the transmission fluid while the car is on ground level? I don't know how's that possible since I got to jack the car up to get to where the oil filler plug and drain plug underneath the passenger side.

Also the plug sit sideways and I'm not sure how to fill the transmission fluid.

Here's the instructions I'm reading. Can anyone help me out here. I'm also not sure what the size of the drain plug washer I'm supposed to change. Do I need those special funnels or something...I'm not sure what their called.
