Mazda Miata: 2003 Miata 6SPD Tranny fill plug

Hello to the group:
Can someone tell me where the Transmission fill plug is on a 2003 6 Spd? There is a 24mm plug on the drivers side which is simular to the drain plug, and then there is a brassy looking plug up on the passenger side which looks like it could be a fill plug.
I've heard that if the wrong one is taken off, damage could result to the transmission.
Thank you

On the 2001 6 speed it is the 24 mm on the drivers side. I just changed my trans and differential oil and found out the fill on the differential is 23 mm not 24 like the rest. I had to run out and get a socket half way through the job.
