...the fill plug on for an auto transmission in a 96 integra.

For some reason its shifting like crap, so I want to put some fluid in to see if it helps. But can't figure out where the damn fill plug is.

 

you fill through where the dipstick sits, its on the passenger side way down there, very hard to see, should be no more then a few inches in front of the battery if you look down there you will see the yellow handle, pull that up, the fluid is in there. Make sure the tranny is warm, running, and in neutral when you check it.
