ok, i have a stock 90 crx Si. D16A6 and it doesn't seem like theres a real sneaky way to fill it up with fluid.. it seems like the only two things on top of the tranny are the drain hose, and this other black thing that doesn't come out or move(that must be the VSS...) but mine looks different than every other pic i've seen on here....

so can i fill the whole thing using the drain hose, and just use the hose as a fill hose?? or what else could i do..

also: what would be the best way to flush it out, and what should i use to do that?

 

What's wrong with putting it in through the filler hole?

 

im not sure on that engine but cant you put it through where the speed sensor is?
