4R70W VSS reading?

98~2001 4-door Explorer is off the rear axle ABS sensor (like a 98~00 Ranger) and is adjusted in the 4WABS module. 96~97 is directly from a signal generator on the transmission or transfer case just like a 95~97 Ranger.

I believe that the transmission shift points are primarily based off corrected VSS and load. There are secondary shift point limitations determined by RPM but they are more for near redline than for part throttle.
Keep in mind that the 98~2001 Ex PCM does not use the rear ABS signal directly. It is first changed from a low voltage sine wave to a 0~12v square wave in the 4WABS module. It is also corrected for tire diameter in the 4WABS module. The output 12v square wave is then used by both the speedometer and the PCM. If you could find a 1356 that will accept a signal generator, that might be OK to be used directly by the PCM.

Obviously, the ABS would be DOA if the rear axle sensor is eliminated. This may not be a good thing, especially on the street, because the 2001+ 4WABS also provides electronic front/rear proportioning.

oh thanks alot man. thats amazing to hear. i figured i was gunna have to make some kinda tone ring to connect up where my driveshaft bolts up and throw the vss sensor there.
but awsome! im stoked now. i was really kinda worried about that. just hope your right haha
but i do remember seing a vss when i was doing my manual tcase swap
