Default Any differences between 98 and 03 4L80e?

Just wondering if GM made any changes in the wiring on between the 98 4l80 and the newer LS style transmissions. I am putting a 4L80e behind my LSX 427 and I wondering if there is something to look out for when it comes time to wire everything in.

Yep what he said! Do a search in this section for a thread I created on swapping to 4l80e. You should find all the info you need in there.

Don't even need to search. Just look at the second sticky and the link is already there.
