I don't have pics, but once you remove the splash shield, you'll see it. It looks like a round-head bolt with a square in the middle - use your ratchet and an extension to turn it -- no socket required. It's probably the only one down there that looks this way. Make sure you can remove the fill bolt BEFORE removing the drain bolt!!!
if i have time . i will take pictures of what im talking bout.. everybody usually does it through the side hole but filling it can be a pain... theres another fill plug right on top of the tranny. if you down you can see it... tricky to get the socket on, but its doeable and filling is easier
i just did mine last week, oil came out a little yellowish, looked sorta like newer motor oil, however the new OEM Honda/Acura MT fluid was almost clear when i filled it back up
i filled it thru the top, there is a rubber black cap with a breather hole in it sitting over a metal tube, almost directly under the air intake hose, i filled from here, took a little while tho, it kept gurgling and glugging as it took 2.1 liters but it eventually all went in, this was the easiest option for me at the time
no noticeable gains... maybe a hair smoother... im sure my tranny enjoyed some freshies tho, and thats all that matters to me
