IMO, if you're going to do an OD auto, don't base it on your' existing power levels, step it up so you don't have to do it again for future power levels.

If you're considering a 4L60e, then you might as well do a 4L80e. It's about the same money and handles way more than a 2004R or 4L60. They are 'roughly' the same size, and if you trim the case it requires no tunnel mods. (search here it's been done before).

Some swap vendors offer generalized kits, but really all you need is a crossmember and driveshaft. And of course, a controller.
