I agree with Kejross You can change it yourself its's fast, fun and easy (ok it's not fun but hey I took a shot) jack up car, put a catch pan under tranny take all bolts off of ONE Side only, fluid will begin pouring our when it stops slowly remove the rest of the bolts working back as you do more fluid will come out, when you get the pan off pull out the filter and O ring (If the ring is stuck use a plastic putty knife to pry it out or if it looks in good shape you can leave the old o-ring in) replace filter and o-ring (if needed)If your tranny had a thick hard poly gasket reuse it if it had a thin rubber one replace it, bolt pan back up fill to correct level. Done if you want to get do a better flush (see some fluid is still in the torque converter) after about a thousand miles change it again.
