However, the exact location can vary slightly depending on the specific transmission type (e.g., 46RH, 42RE). You'll need to consult a repair manual specific to your van's transmission for the precise location and visual identification. A diagram showing the transmission and its components will be invaluable.
To find it, you will likely need to:
1. Consult your repair manual: This is the most accurate way to determine the location.
2. Look near the tailhousing of the transmission: This is the rearmost part of the transmission.
3. Inspect the transmission for a small sensor with a single wire connector. It might be near the driveshaft yoke.
Remember to always disconnect the negative battery terminal before working near the transmission or any electrical components. If you're not comfortable working on your vehicle yourself, it's best to consult a qualified mechanic.
