It would not shift from first gear

My Caravan transmission failed out of town and I had it rebuilt. Worked fine for about 8 months. Then after about a 5 hour drive, it lurched a little on the highway exit ramp, and the speedometer failed. And it would not shift from first gear.

Speed sensor right? Well the plug to the speed sensor must have been loose and caught on something as it is completely gone!

I was unable to get to a junkyard so I bought a new speed sensor with a pig tail. This part was cross referenced at Advance Auto it was a 3 wire instead of a 2 wire. I could not tell where the original wires ran from, so I replaced the speed sensor and ran the new plug to the wires as shown in the schematic.

Now the speedometer works but it still will not shift and putting it in gear it shifts hard.

A mechanic friend had me pull the battery terminals to clear the computer, same thing.

Checked tranny fluid and it is topped off and okay.

Is my tranny shot or did I foul the wiring? Tranny is out of warrenty and if it wasn't I would not want to drive 300 miles to the shop that rebuilt it.

Just trying to get it through a few more months before I can replace the van.

Thanks!
