Transmission fluid can be changed. It isn't needed changed often unless the transmission is damaged. It isn't as easy a job as changing engine oil. Usually the trasnision pan has to be removed to get at the transmission filter, which is inside. Look in Chiltons Auto Repair manual to see if you want to go though all that- or if you can do it. Also, transmission fluid is specific to particular vehicles and if you put in the wrong fluid, it will damage the tranny by destroying the seals, and transmision multi-plate clutches.
If there isn't a problem, don't create one. I doubt your jeep needs a tranny fluid change this soon. Let the service dept look at it if it's acting up.
