If the transmission was properly maintained by the previous owner (regular fluid/filter changes), and you plan on continuing that maintenance plan, you should have many more reliable miles to go.
If you have no clue if the previous owner did anything to it, and you yourself have neglected to do any maintenance regarding the transmission, failure is on the horizon. To prevent catastrophic failure, have your service provider do a fluid inspection/test drive to check for pending problems.
