* Engine and Transmission Compatibility: Even if you found a Mazda transmission that *theoretically* could handle the Ford Probe's engine power, the bolt patterns, input shafts, bell housings, and clutch systems would be entirely different and require extensive custom work or adapter plates (which might not even exist).
* Driveshaft Modification: The driveshaft length and connection points would be completely incompatible. A custom driveshaft would be essential.
* Transmission Tunnel Modification: The Ford Probe's transmission tunnel might not accommodate the Mazda transmission's dimensions. Significant modifications to the chassis would be required.
* Wiring and Controls: The wiring for the clutch, shifter, speed sensor, and reverse lights would need to be completely rewired.
* Computer Issues: The Ford's engine computer likely won't be compatible with a Mazda transmission.
In short, while theoretically *possible* with extreme mechanical skill, time, and resources, it's not a practical or realistic conversion. It would be far easier and cheaper to find a Ford Probe with a manual transmission already installed or to pursue a different swap using a more compatible transmission.
