I've never replaced one yet on a 3800. But it does not look like a big deal. I believe someone on MCF posted a step-by-step guide on doing it.
If it is the pump, I might recommend AC Delco part 252-693. This is a 3800 Series III pump. From what I understand a 3800 Series I, II and III pump is the same (except a Series I uses a different pulley). The primary difference is the Series II has a stamped steel impeller, which is not as effective as the cast aluminum impeller on the Series I and III. Series III pumps let you use your stock pulley, bolts up no problem. Also, I know some people who recommend if the pump comes with the plastic gasket, spring for an extra couple of bucks and get the paper one (more reliable seal).
This is info I gathered from the Bonneville guys.
