Confirm the engine, tire package and service procedure
Match your engine and transmission with the configuration selector. Check the door-jamb tire label for your installed wheel package and cold pressure. A capacity is not a substitute for the filling procedure in the owner's manual; transmission change quantities and total system capacities can describe different jobs.
Fields marked Not published have no compiled value here. They do not mean zero capacity, no maintenance requirement or permission to substitute a part. Request a specification correction with the exact year, engine and manufacturer reference.
