I have a 2012 front wheel drive Crosstour, and just replaced the coolant and transmission fluids in the car. The first bit of advice I will give you is to use only genuine Honda fluids, they have additives in them that help protect whatever they come in contact with that most OTC fluids do not have. Honda fluids only cost a few dollars extra, but the peace of mind is priceless. For the transmission, do not have it power flushed, this is one of the most damaging things you can do to any transmission, regardless of manufacturer. When power flushing, small bits of metal or dirt can get lodged in small areas and actually cause uneven wear or a blockage. I followed these videos to replace my transmission fluid 3 times in one day, which SAFELY replaces at least 90% of the fluid in the transmission. I also used the other videos I am sharing here. I did take my car to my local dealership to flush out the brake fluid though, I couldn't find anything on that.
Assuming you have the 2.4L engine, these videos will help you a lot. The transmission on the V6 is a little bit different, but the procedures are pretty much the same. I don't have AWD in my car, but I am sure you can find a video showing you how to service your transfer case and rear differential. He is working on an Accord, but the Accord is mechanically identical to a Crosstour.
