Hey! Is changing transmission fluid on a 2014 Lexus is350 with 100k miles a good idea? It has not been changed before. It has been well maintained otherwise throughout its life.

At 100,000 miles, I would go ahead and change it now (drain and fill with filter change , if applicable).  Be sure from this point onward you are changing it no later than every 60,000 miles (and I actually go more aggressive at 40,000-50,000 miles).
