Automatic Transmission Question

I've got an '01 Sport. Were there any other automatic transmissions used on these other than the AW4? I'm planning on doing a fluid/filter change and I want to make sure I have the right stuff.

AW4 trans with all 4.0 LTR motors. Buy only Dex III Mercon. Remember you will only be draining 3qts +- from the pan. If it has never been changed or the fluid appears dark,I would recommend changing it once ,driving it for a short while and draining it again. It will take at least 4 changes to get rid of most of the old fluid. I changed mine twice and again twice three thousand miles later. I also added a product called Lube Guard (Advance Auto,NAPA) after the last change and the transmission shifts better than when it was new.
Good Luck,
Jeff
