Finding a replacement transmission requires checking the code and finding a used transmission with a matching or very close code. Even then, you might need to adapt some parts or even have some minor modifications made by a transmission specialist. It's not a simple bolt-in swap.
To find the correct replacement:
1. Locate your transmission code: This is usually stamped on the transmission case itself. You'll likely need to get under the van to see it clearly.
2. Use that code to search for compatible used transmissions. Auto parts stores, salvage yards, and online resources that specialize in used auto parts will be your best bet.
3. Consult a transmission specialist or mechanic. They can verify compatibility and advise on any necessary modifications before installation.
Using the wrong transmission can lead to serious mechanical issues and damage. Don't attempt this repair without professional guidance if you're not experienced with transmissions.
