Rumor has it that there were indeed some electrical changes in 2000. However, when I compared the pinouts on the connectors, they were the same....... So, changing electronics in the trans may, or may not... make any difference. Be aware, that the mountings changed for the governor pressure solenoid as well... so, in order to change to the older version electronics, need some parts off the old valve body as well.
