100CSQ Auto Tranny question & Bose system

[Robert Manger]

I just purchased a 93 100CSQ in silver, great car so far.  Wondering if you
are supposed to change the auto tranny fluid and if so?  How often?  and
what is the preferred type of fluid?

My car has the bose system which seems to be ok in regards to sound
quality, but I would like to add a cd changer or at least an in dash cd
player.  Is it possible, some how I think not, but it is worth a try.

Thanks,

Rob
