Just a quick question - why do you want to change it? Do you have a lot of miles, or having issues with your transmission? I don't have it in front of me but I think the first scheduled service is at 100k miles.
My last vehicle, a 1996 Subaru Impreza, advised that under normal circumstances the transmission fluid & filter should never be changed. I was a little nervous about that, but followed the recommendation. When I traded it in the odometer read 235k miles, the transmission still had the factory fluid installed, & I never had a problem with it.
Unless you are having an issue or are reaching the maintenance interval, you may be just as well off to not change it.
