Will a 1987 transmission from a v6 fit a 4 cylinder?

A 1987 transmission from a V6 is generally not compatible with a 4-cylinder engine due to differences in size, mounting points, and gear ratiOS. Each engine type is designed to work with specific transmissions that match its power output and performance characteristics. Always consult a vehicle service manual or a professional mechanic to confirm compatibility for a specific make and model.
