    ISSUE
    Some 2007-2010 Expedition, 2009-2010 Navigator and F-150 vehicles equipped with a 5.4L engine and a 6R75/6R80 transmission may exhibit delayed forward/reverse engagement. Diagnostic trouble codes (DTCs) P0741, P0731, and/or P0735 for torque converter and/or gear ratio concerns may be stored in the powertrain control module (PCM). This concern typically occurs after cold start and in colder climates.

    ACTION
    Follow the Service Procedure steps to correct the condition.

    SERVICE PROCEDURE

    1. Remove the mechatronic assembly. Refer to Workshop Manual (WSM), Section 307-01.

    2. Inspect the fluid pump adapter seal molded frame for evidence of cracks, which are most often found in the corner(s) of the molded frame.

    a. If evidence of cracks are present, proceed to Step 3.

    b. If evidence of cracks are not present, do not continue with this article. Refer to WSM Section 307-01 for further diagnostics.


    3. Partially disassemble the mechatronic assembly to access only the main oil pressure regulator valve located in the lower half. Refer to WSM, Section 307-01.

    4. Inspect the main oil pressure regulator valve for free movement in its bore.

    a. If the valve moves easily in the bore, proceed to Step 5.

    b. If the valve does not move or sticks, remove the valve and clean both the valve and bore, reinstall the valve. Proceed to Step 5.


    5. Reassemble the mechatronic assembly. Refer to WSM, Section 307-01.

    6. Install a new front pump adapter seal.

    7. Reinstall the mechatronic assembly. Refer to WSM, Section 307-01.
