2004 Transmission into a 2000.
I have a 2000 Crown Vic with a dead transmission, a friend offered me his 2004 Crown Vic Transmission. Both are P71s, BUT I have been told the VSS is not the same and it is impossible to change without a complete tear down and rebuild. What is the difference, I believe it is the pulse rate if so what is the rates for a 2000 and then a 2004??
