OK Here is the info for all who want to know. In 03 they went from Red and Blue pcm connectors to Blue and Green. The Red pin placement and Green pin placement are the same for the 4l80e speed sensor position. So if you use Red 22 and 23 for the speed sensor you will now use Green 22 and 23. The 22 = red & blk wire and high speed, 23 = blue & white wire low speed.
