For the E4OD transmission, the capacity is typically between 10-12 quarts. This is a range because some fluid remains in the torque converter and cooler lines when the pan is drained. It's best to use the higher end of that range (12 quarts) to ensure you have enough.
It's crucial to consult your owner's manual for the precise capacity for *your* specific truck. The manual will have the correct information based on your truck's build and any modifications that might have been made.
Failing to find your owner's manual, you can try these resources:
* Ford's website: They might have online resources for owners manuals.
* Online parts retailers: Search for your vehicle's details on sites like AutoZone, Advance Auto Parts, or Napa Auto Parts. They often show diagrams and specifications.
* A local mechanic: A mechanic familiar with Ford trucks can quickly provide this information.
Important Note: Simply refilling the transmission to the level indicated on the dipstick is not a complete fluid change. For a full fluid change, a process of multiple partial drain and refills is recommended to completely replace the old fluid.
