    Can anyone describe and give a visual what's different between these transmission. In eternally and externally?

    Going off memory the valve body is for sure different. The way the transmission is controlled through the wiring harness is different as well.

    2003 is when they started to change things up.


    Found the post through google because I don't have facebook.

    Can I modify a 1997-2002 4T65E... - GM 3800 Transmission Section - 4T65E | Facebook

    Thanks! I wonder If the spacer plate holes are the same? I know 03+ spacer plates have molded gaskets
