new to the volvo scene. bought a 99 s80. got a few questions.

hey everybody. first time on this site. i recently purchased a 99 volvo s80 and i was wondering if any of you guys had any info on these cars that you might like to share with me. (factory defects, S80 specifics) it has 120k on it, so i was wondering if you guys can recomend a good set of shocks that wont cost me my right arm. also, what kind of fluid does the automatic transmission take? (inline 6 cyl, non turbo) is it just regular old dextron mercon 3? or is it something special? and once i change the tranny fluid, how do i reset the message indicator so that it no longer says "transmission service"? and does anyone know a way to program my own keyless entry that i bought off of ebay?(its made for this car. its the original.) have any of you ever had any trouble with the airbag light? the car has a clean carfax report, so i dont think its ever been wrecked. i want the light to go off, but i dont want to pay the $400 the stupid dealership probly wants to diagnose and fix this. ok so i had a lot of questions. i used to have a 95 850 turbo. thats why i love volvo's now.
