Jason, you have much to learn, and that's OK.
First off, there is no such thing as a liftime ATF fluid ( or ANY auto fluid, for that matter). The additives are being used/broken down every time you drive. At 110k you need to get the old fluid out and some new stuff in. If I were you I would do a complete flush with either the Toyota WS fluid from the dealer or with some Red Line D6 fluid, which is superior to the WS fluid, in my opinion. You can buy Red Line online from many sources, including Amazon
There is a very good ATF flush tutorial on this forum, in fact it's posted in this very thread in post #4. Just scroll up and click on it.
I have no idea why Toyota would tell you not to change the fluid at 100k, that's just plain ridiculous. Franky, hearing crap like that is why many of us avoid the dealers like the plague, and have learned to do many things on our own, including changing out the ATF.
BTW, from '05 on, any of the 5 or 6 speed auto trannies came with the WS fluid, but the 4 speed trannies ( like the one in my 06 standard cab ) came with the T-IV fluid. The trannies with WS fluid do not have a dipstick, the ones with T-IV do have a dipstick.
