definitely GET! like e-t said, as long as the beast is running good... make sure you check everything out, and get some good fluids in there, and you (and your NEW car) will be happy!
let us know how you make out and if you need any help... CONGRATS!
p.s just thought, b4 you change the tranny fluid, check with someone or try to find out if it had been replaced or rebuilt, or still original. sometimes new fluid in an older tranny can 'bring up' new problems. if it looks REALLY clean, and you have no leaks or unusual noises/shifting, might be better to leave be.
