100,000 mile maintenance

My 03 automatic is coming up on the 100,000 mile mark, and I was wondering what maintenance I should be performing. I haven't had any enigine or drivetrain problems so far, but I want to be proactive.

Just my opinion, but I'd replace the diff fluid every 50k miles. No reason to give these rear ends more reason to howl louder than they already do!

You may want to replace your Dexcool or give some thought to replacing it with the green stuff. If you go green, you'll need to do an excellent job of flushing out the Dexcool though. This is a heated topic so others may chime in on the coolant issue. I'm still not sure what I'm going to do in this regard.

Good Luck.
