Differences from 2004 4l80e vs 97-03 4l80e
Also the tail housing seemed to have a diff bushing, and when I orig built mine there wasn't one avail from Trans star (I think that was the place)
I never could find out if the valve body itself was diff, as I needed one to replace the one I had (changing from an HD-3 kit) I know there is a diff bet older ones and later ones-I picked up a later one, just not an 04, but didn't use it
I also saw some mixed opinions on whether the pump was diff, but I don't think so-I ended up with another 04, so I just robbed the VB off it, lol
Some of the books have older info, so its hard to keep up with later changes
