I believe a regular 98-02 LS1 T56 would bolt up the same but then you have the added cost of modifying it for a mechanical speedo drive if you aren't using an electronic speedometer.

On the olds we had to have a custom pilot bushing made because the auto crankshafts are different than the manuals. Not sure if Pontiac is similar in this regard.

You will need to modify/rebuild your trans tunnel as well.
Just putting in a 2nd note about trans tunnel modifications. GM A Bodies have a small tunnel area. T56 is huge and doesn't taper down behind the bellhousing. The lower your car is, more surgery required. I'd love to do a t56 swap, I can't cut up my OE floors on my Chevelle. Yet!
Nice looking GTO and poncho powered. I'm huge A body fan!
