No, a 1998 Ford Ranger manual transmission is
not guaranteed to fit a 1993 Ford Ranger. While they're both Rangers, there were changes in drivetrain components and configurations over those years. The bellhousing (the part that connects the transmission to the engine) is a key area of concern. Even if the transmission case itself seems similar, the bolt patterns and input shaft might be different, preventing installation.
You'd need to verify compatibility by checking the specific transmission codes (found on a tag on the transmission itself) for both the 1993 and 1998 Rangers. Even with matching codes, there's still a small chance of subtle differences causing problems. It's safest to assume they're not interchangeable without confirming this with a parts catalog or a Ford specialist mechanic.
