1996 Dodge Caravan will a '93 tranny interchange with '96 t

I was told that the '93 tranny would interchange with the '96. All I would need to do is switch out the three sensors, and rewire the starter switch. I've switched two of the sensors, the input and output speed sensor. The range sensor plug on the vehicle doesn't match either the prndl switch or the neutral start switch receptacles on the '93 tranny so I guess that's why I can't get the engine to start. I've rewired the starter switch to a button and it does crank ok. I've probably wasted my time but if someone has any ideas to make this work it would be greatly appreciated. Thanks
