How much transmission fluid does a Dodge Avenger need?
Typically around 10 quarts for a full fill on the common four-speed automatic, and about 4–5 quarts for a drain-and-fill. Exact figures depend on the model year and the specific transmission installed in your Avenger.
The transmission fluid capacity of a Dodge Avenger varies with year and transmission variant, so it’s important to check the exact specification for your vehicle. This article outlines typical capacities, how they differ by service type, and best practices for selecting and adding fluid.
Typical capacities by service type
Before listing, note that these figures are general guides for Avengers with the common four-speed automatic. If your car has a different transmission or a regional variation, capacities may differ.
- Full system capacity (complete fill, including cooler lines and all fluid in the system): about 9–11 quarts (approximately 8.5–10.5 liters).
- Pan drain and fill (draining the pan and refilling without replacing all cooler line fluid): about 4–5 quarts (roughly 3.8–4.7 liters).
- Fluid exchange/flush (most old fluid replaced via a professional machine or a thorough manual exchange): about 11–12 quarts (roughly 10.5–11.4 liters).
Capacities can vary by year and the exact automatic you have, so confirm the spec for your vehicle from the owner's manual or a manufacturer service sheet.
Fluid type and installation tips
Using the correct fluid type and following proper procedures are essential to protect the transmission and ensure accurate level readings.
- Use the recommended transmission fluid for Chrysler/Jeep/Dodge automatics, typically ATF+4 for most Avengers’ automatic transmissions.
- Avoid mixing ATF+4 with other ATF types. If you’re unsure of the current fluid type, consider a controlled drain and refill to the correct specification.
- Check fluid level with the engine warm and the transmission warmed up to operating temperature, following the manufacturer’s procedure (Park, engine running, gears in Park, etc.).
- Some markets and model years may not have a dipstick or may require a specific read procedure; always consult your manual for the correct level-check method.
Incorrect fluid type or overfilling can lead to shifting problems or fluid foaming, so accuracy matters more than speed.
How to perform a safe transmission service (high-level)
Below is a general guide for a standard pan drain and fill. If you’re unfamiliar with transmission work, consult a professional shop.
- Make sure the car is on level ground and the engine is at operating temperature.
- Prepare tools and a drain pan, new pan gasket if needed, and the appropriate amount of ATF+4 fluid.
- Drain the pan and remove old fluid. If the transmission is field-serviceable, replace the filter as recommended by Chrysler/vehicle data.
- Install the pan with a new gasket, reinstall the drain plug securely, and refill with the recommended amount of ATF+4 in stages.
- Run the engine, cycle through gears to distribute fluid, then recheck the level and adjust as needed to the correct spec.
Note: A full flush or fluid exchange may require more fluid than a simple pan drain and fill. Follow the service equipment’s guidance and the vehicle’s manual for exact quantities.
Summary
For most Dodge Avengers with the common four-speed automatic, plan on roughly 9–11 quarts for a complete fill and about 4–5 quarts for a standard drain-and-fill. Always verify the precise capacity for your year and transmission variant, use the recommended ATF (typically ATF+4), and follow the official level-check procedure to avoid overfill or underfill. When in doubt, consult the owner’s manual or a qualified technician to ensure the correct specification and service procedure for your specific vehicle.
