^ Just buy a funnel, get a suitable length and diameter clear tubing, so it fits tightly over the funnel (or inside of it, but it takes longer to pour that way) and then insert it into the fill hole from above, with the hood up. You put the car down off the jack stands first, after draining the trans., then fill it, so it fills to the correct level (assuming it's level ground, or close to it).

As for the manual transmission fluid, gear oil (actual gear oil, not meaning any sort of oil meant for the manual gearbox) is better than nothing at all, but I wouldn't advise it on a Honda/Acura trans. I'm not 100% sure how well it would protect, might do fine (as long as it's no thicker than a comparable 10w40 motor oil) but it won't shift nearly as well, and that's best case scenario. Never tried it myself, but that's what I've been told and have read.

P.S. and again, I meant no offense, you clearly know about cars (and apparently Hondas too as you pointed out) but a few of your suggestions have been off (more suited to other makes it seems), not that I'm always right by any means
