I just bought a 2001 Taco V6 auto myself(I love it!) and it came with the factory hitch. I think calling it a tow package is a bit mis-leading.....it's just a tow hitch as far as I know. I don't seem to have the external tranny cooler or an extra core in the radiator....or lower ring/pinions. Mine is a class 3 and that is 5000 pounds rated. I guess you will need a class 4....and you probably don't have a tranny cooler with your auto(I assume) so you might as well get that, too.....oh, and don't forget to add a tranny temp gauge. <img src="/forums/images/graemlins/cheers.gif" alt="" /> ZUK
