The transmission temperature sensor on a 1996 Dodge Ram 1500 is located on the driver's side of the transmission. It is just behind the bell housing. Look for a gold plug with a black plastic top.
Possibly, but you will run into computer, sensor, and wiring differences. It would be easier to get the proper engine.
