2006 Ford Expedition Automatic Transmission Filter Parts Q&A

• Q: How to Service and Repair the In-Line Automatic Transmission Filter for the 4R70E/4R75E Without an OTA Cooler on 2006 Ford Expedition?

  A: Proceeding with service or repair of the in-line filter for 4R70E/4R75E automatic transmissions absent an OTA cooler requires placing the vehicle in neutral and elevating it on a hoist. The installation of a new in-line fluid filter becomes necessary when servicing the transmission that originally contained this type of filter. The transmission requires an in-line fluid filtration system so obtain and install new filter elements if there is no existing filter in place. A filter or filter kit should not be installed when putting new transmissions that need no internal repairs. A new or Ford-authorized remanufactured transmission requires the installation of the filter provided by the manufacturer. Remove the retainers on cooler tubes and section of steel tube before cleaning and deburring the steel tubes' ends. Insert the cooler tube completely into the fitting before beginning ferrule nut tightening. The initial finger tension should be followed by 1.5 additional turns. Install the filter into the fluid cooler return line with its red arrow facing away from the transmission fluid cooler in the direction of the transmission. The filter contains a bypass valve. It is vital to prevent the installation of rubber hoses and steel tubing with bends exceeding 60 degrees when they lead into the filter. The filter installation requires suitable hose length while hose clamps need to be properly tightened. You should install one cooler tube retainer before you secure the cooler tubes with a tie strap. The transmission fluid pan requires cleaning before placing the sticker onto its designated section. You must proceed with filling the transmission with new automatic transmission fluid before checking that the system works correctly and looking for any filter leakage.
