where do you add transmission fluid at?

Should be a dipstick towards the driver's side of the car facing the engine compartment. Probably has a yellow or red handle, likely red.

dude has a GS-R though, not an automatic transmission. check this link out. http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=301

1 way is, u can take out the speed censer r and put the oil through there or lift up the car from the front passenger side and take off the dat passenger ring and u should see a bolt dat is size of a 17mm or a 19mm. after u take dat out u have to use a pump to in order to put oil through dat aria... and also do not use transmtsion oil. u have to use motor oil if ur car is a 5 speed but if its an automatic then u can u the transmision oil

first, dont take off ur speed sensor, that will solve nothing. drain it at the drain plug and fill it at the fill plug which should be on the passenger side right above the cv. second, you definitely dont need a pump, all you need to do is fill it though the hole until you have fluid dripping back out, then you stop. third, you dont EVER use motor oil in a tranny, motor oil doesnt have the same chemical make up let alone the detergents that trans fluid has, in short if you use motor oil kiss ur trans good bye in probably 10k miles or less. so if its an automatic, use Honda ATF. if its manual use Honda MTF (Manual Transmission Fluid). always use honda fluids in the tranny.
