* Internal Components: The internal parts, including gear ratios, valve bodies, and even the overall design, will be different.
* Computer Control: The 1996 model likely uses a more sophisticated computer-controlled transmission than the 1993 model. The 1993 transmission simply won't be compatible with the 1996's electronic controls.
* Mounting Points: While the transmission case *might* look similar, the mounting points and bolt patterns could differ, making physical installation impossible or very difficult.
* Driveshaft: The driveshaft may not be compatible due to differences in the transmission output shaft.
In short, even if you could somehow overcome the physical installation challenges, the electrical and internal incompatibilities would render the transmission unusable. You need a transmission specifically designed for a 1996 Ford Explorer.
