Generally:
* Manual Transmissions: Manual transmissions typically require less frequent fluid changes than automatics. However, even with manuals, inspecting and potentially changing the fluid every 3-5 years or 50,000-75,000 miles (80,000-120,000 km) is a good idea, depending on usage (heavy towing will require more frequent changes).
* Automatic Transmissions: Automatic transmissions in Sprinters are more complex and require more frequent attention. Consult your owner's manual for the *specific* recommended interval for your van's year and model. This interval can range from every 30,000 to 100,000 miles (48,000-160,000 km), or even longer in some cases, but frequent inspection is crucial. Heavy use, towing, and harsh driving conditions will necessitate more frequent changes.
Crucially: Always refer to your owner's manual. It will provide the manufacturer's recommended maintenance schedule, which is the most reliable source of information for your specific vehicle. Ignoring the recommended service intervals can lead to premature transmission wear and costly repairs.
If your owner's manual is unavailable, you can try contacting a Dodge dealership or a reputable Sprinter repair shop to obtain the correct information for your vehicle.
