I recently put a 2001 4r70w into my 1998 with a 4r70w. It will not shift, I can physically move move the shifter but it will not shift out of park. I have been doing some research and sorta found out about the difference between a vss and oss. How would I get this to work? I swapped out my old tail shaft cover and sensor from my 1998 4r70w and it still will not shift. What am I doing wrong?
