Listen to tighen1---he is one of the smarted guys on here. The book says the trans fluid should be replaced at 80k. Do you have any records? If not check the stealership and see if they do. Maybe they do. If you are going to service it---DO IT NOW!!! There is a point of no return, and you just leave the fluid in until failure of the transmission. When I had my repair shop, I would tell my customers that the fluid is ALWAYS cheaper than the part the fluid is in. If you do service, replace that known seal that I talked about in my last post.
