My brother has a 1998 V8 Sho with the AX4N transmission. It has the cam issue that's common to these things, plus a few more issues. I found a 1999 Taurus with the 3.0 V6 Duratec and AX4N transmission that's bad. We put the transmission from the V8 Sho in the V6 Taurus and everything bolts up. But, the Sho transmission doesn't have the speedometer/odometer plug that the V6 transmission has. It has a plug instead. After putting the transmission in, it will go into Drive and Reverse, but once on the road it will not shift. Question is, is the shift pattern generated by the speedometer? What makes the transmission shift? Any help would be appreciated. Thanks.
