Did you count the number of shifts? If you have access to a scan tool that will view trans computer data, you can see the W S switch and trans shifter position.

If no scan tool, you should be able to probe the trans computer inputs looking for the W S signal. I'm pretty sure the trans shifter position is either variable resistive or 4 bit binary.




At least on the 97 MY, the MB star must be removed ( it is on with 2 sided foam tape ) and a torx bolt removed.
