To find it, you'll need to:
1. Consult your owner's manual: This is the best place to start. It should have diagrams showing the location of various components, including the transmission.
2. Look closely around the transmission: The breather is usually a small cap or vent, often located on top or on the side of the transmission case, often near a higher point to prevent fluid from escaping. It might be a simple rubber cap or a small plastic fitting. Expect it to be somewhat hidden or tucked away.
3. Use online resources: Search for images of your specific transmission model (e.g., "2004 Dodge Ram 2500 47RE transmission breather") on sites like Google Images or YouTube. You might find a picture showing its location on a similar vehicle.
4. Check transmission repair forums: Forums dedicated to Dodge diesel trucks often have discussions and pictures about transmission maintenance, and someone might have posted a picture showing the location of the breather.
Important Note: Be careful when checking for the transmission breather. The transmission case is hot when the vehicle has been running, so allow it to cool down completely before handling the area.
