    possibly a trans. i would do some research and see what trans those later year 3.1s came with. if it came with a 4t-60 or a 4t-65 non hd, i would switch over to a 4t-65hd.

    If you have the 3.1L and plan on dropping a S/C 3.8L in you will need to find a 4T-65E HD Transmission to drop in. The 3.1L come with the standard 4T-65E.
