It's
unlikely a 1997 Dodge Dakota automatic transmission will fit a 1993 Dodge Dakota without significant modifications, if at all. While they are both Dakotas, there were changes to the transmissions and related components over those four years. The bellhousing (which connects the transmission to the engine) is a key area of concern. Even if the transmission case seems similar, the bolt patterns, input shaft size, and other crucial dimensions could differ.
You would need to verify the transmission part numbers from both vehicles to confirm compatibility. Even then, simply matching numbers doesn't guarantee a perfect fit; there might be subtle differences affecting installation. It's best to consult a transmission specialist or a mechanic experienced with Dodge Dakotas from this era. Attempting this swap without expert knowledge could result in damage to your vehicle.
