Lots of horror stories with the trans flush. Just replace the fluid, and think about an accessory cooler and filter. You're in for a surprise with the wires, as this car has a coil on plug set up, and a set runs about $400+. If there are no misfires, or idle problems shine that part of the "tuneup" on.
Welcome, and get ready for a lot of reading. Premium fuel is specified.
