In short: No, not easily or directly into any other car. While some parts *might* be interchangeable with other Mitsubishi vehicles from around the same era (particularly other 1G DSM cars like the Lancer and Galant), a direct swap into a non-Mitsubishi vehicle would be exceptionally unlikely without significant custom fabrication. Even within the Mitsubishi family, you'll need to match the transmission to the engine and drivetrain components. The bellhousing (which connects the transmission to the engine) is a key area where compatibility is crucial.
To determine compatibility, you'd need to:
1. Identify the exact transmission code: This is usually stamped on the transmission case itself.
2. Identify the specific car you want to install it in: Make, model, year, and engine are all critical.
3. Research transmission compatibility: Online forums dedicated to Mitsubishi cars (especially the DSM community) or transmission specialists are your best bet for finding this information.
Without this information, any answer would be purely speculative and potentially misleading.
