25. Use the following guidelines for installing the in-line transmission fluid filter:
- If the transmission was overhauled and the vehicle was equipped with an in-line fluid filter, install a new in-line fluid filter.

- If the transmission was overhauled and the vehicle was not equipped with an in-line fluid filter, install a new in-line fluid filter kit.

- If the transmission is being installed for a non-internal repair, do not install an in-line filter or filter kit.

- If installing a new or a Ford-authorized remanufactured transmission, install the in-line transmission fluid filter that is supplied.
- Prior to lowering the vehicle, install a new in-line transmission filter or a filter kit. For additional information, refer to Transmission Filter - In Line Transmission Filter - In Line.
