To determine what transmissions are interchangeable, you need to specify the year of your Dodge vehicle. Different years used different bellhousing patterns, and even within the same year, different transmission options were available depending on the model and trim level.
Common transmissions paired with the 318 include:
* Torqueflite 727 (3-speed automatic): This was extremely common, but the bellhousing pattern changed over the years. A 727 from one year may not fit another.
* Torqueflite 904 (3-speed automatic): Less common than the 727, but still used on some models. Again, year-specific bellhousing patterns are crucial.
* Torqueflite A518 (3-speed automatic): A more modern 3-speed automatic, but not interchangeable with earlier 727s or 904s without significant modifications (potentially including adapter plates).
* Various manual transmissions: Several different manual transmissions were offered, often specific to the vehicle's year and model. Interchangeability is highly dependent on the specific transmission and the vehicle's year.
In short: You *must* provide the year and model of your Dodge vehicle to get an accurate answer about interchangeable transmissions. Checking a parts catalog specific to your vehicle's year is the best way to confirm compatibility.
