To be absolutely sure, you need to:
* Verify the engine: The transmission must match the engine. A transmission from a gas engine won't work in a diesel van, and vice-versa.
* Check the transmission codes: Find the transmission code on both transmissions (usually stamped on the transmission case). These codes indicate specific versions and variations. Identical codes are a strong indicator of compatibility.
* Compare the bellhousing: The bellhousing is the part that connects the transmission to the engine. These need to be compatible. A visual comparison might be enough, but ideally you would check part numbers.
Without checking these specifics, you're taking a risk. While it's *probable* a direct swap, slight variations could lead to fitment issues.
