Good morning. The last time anyone posted on this thread was Dec. of last year. While your information is concise and well written, the topic has been beaten to death. There is a consensus from other members and former techs on this forum that support you don't touch the tranny if it has hit 100k and has never been cracked open before. Using the old adage of "if it ain't broke..." The exception would be if the tranny is experiencing problems, then change fluid. You may be looking at an overhaul of the tranny anyway, so as a last ditch effort to squeeze the last bit of life out, you could drop the pan and change the oil and filter, but end result normally is the same.
