To find the correct information:
1. Locate your transmission's identification tag: This tag is usually found on the transmission case itself. It will have a code that identifies the specific transmission.
2. Use your owner's manual: If you still have the original owner's manual, it will specify the correct transmission fluid type and capacity for your particular Ranger.
3. Consult a Ford parts website: Use the VIN number of your truck on a Ford parts website (or a reputable parts supplier website) to identify the transmission and get the correct fluid specifications.
4. Check a reliable online repair manual: Sites like Haynes or Chilton offer repair manuals specific to your year and model Ranger. They will give detailed information on the transmission and its fluid requirements.
Without knowing the specific transmission, providing the correct oil type and capacity is impossible and could lead to damage to your transmission.
