The 2010 Dodge Avenger uses Mopar ATF+4 automatic transmission fluid.
For this model year, the Avenger was equipped with a 4-speed automatic transmission. Chrysler specifies ATF+4 as the recommended fluid to ensure smooth shifting and to protect internal seals; using the wrong fluid can lead to shifting issues or potential transmission damage. Always verify the exact specification by checking the owner’s manual or the transmission dipstick, especially if a dealer or independent shop serviced the vehicle with a different fluid.
Transmission specifics for the 2010 Avenger
In 2010, the Avenger offered two engines—the 2.4-liter I4 and the 3.5-liter V6—both paired with a 4-speed automatic that uses the ATF+4 specification. This fluid is designed for Chrysler automatics from that era and helps maintain proper seal performance, shifting quality, and temperature handling. Confirming the exact specification with documentation or a technician is prudent if the vehicle has undergone prior servicing.
How to verify and maintain the correct fluid
If you are performing a transmission service, ensure ATF+4 is used. Here are practical steps to verify and maintain proper fluid compatibility:
Consult the owner’s manual or contact a Chrysler/Fiat dealer for the precise specification. Inspect the transmission dipstick or service label under the hood for guidance on ATF+4. If there is any doubt about prior fluid changes or if the vehicle has a non-original transmission, have a qualified technician confirm the correct specification before proceeding with a drain-and-fill or fluid change.
Summary
For a 2010 Dodge Avenger, the recommended transmission fluid is Mopar ATF+4. Use ATF+4 for any transmission service, and verify the specification with the owner’s manual or a dealer if you’re uncertain.
