Couple things here.. first, you didn't specify either a model year or transmission model.. BMW has more than one transmission option.
Second, you're on this website asking this question. That tells me that you're not even sure where to begin. Rebuilding a transmission requires a clean environment to work in and precise torquing measurements. I can't help but think you're getting a bit out of your league here. I'd recommend you have a professional do it.

In order to check the transmission fluid on a 2000 BMW 323i, you must first determine whether the transmission is manual or automatic. If it's automatic, it's not suggested that you change it yourself. If it's manual, you should look in the user's manual for instructions.
