I forget what year, but at one point they discontinued using the 2wd pan. If you can't find one, get the 4wd pan (aftermarket pans will be all deep pans anyway) and use the 4wd filter set. It is a bolt in (I have a 2wd and use the 4wd filter set with my PML pan) and will give you a little extra trans cooling with a little more fluid.
