I been searching alot about this but havent found clear information.. does any one can share or would like to help? if it posible with some kind of diagram or explanation of how to do it..

Why i would like to do this?? I just want to know how to do it in case i need it... maybe in a car that has been tuned already and it doesnt has a matching OS for 4L80E swap.. i will save time and will do it simpler

thanks really apreciate it.
