Can't find info on trans segment swaps

[pullincrazy88]

I saw a thread a little while ago that was explaining how people figured out how to get a 4l80e to shift correct in 4 low. Something about doing a segment swap with another 4l80e trans cals. One what is it being swapped to and two how do I do the segment swap? I cant seem to find anything on how to do this and it would be great to get it to shift right.

Thanks joecar! I understand how to do the segment swap but cant find a tune with my OS01270003. does anyone have one from an 01'-02' truck i can try to swap the trans segment from to see if i can get my trans to shift correctly in 4 low. I looked over at holdencrazy and found nothing.

You may have to swap to OS 12212156/02020003/02020005.
