    Here's the parts I bought. 2008 Lincoln navigator with the zf 6hp26. The gasket, mechatronics bridge and the plug were bought from California transmission supply. They did not list the navigator but they do say they are for the 6hp26 and they are zf branded parts.
    The 4 rubber sleeves and filter were bought from Amazon. The fluid from rockauto.
    Mercon sp - $6/quart
    Filter - $41.56
    Gasket - $25
    4 sleeves - $25
    Mech bridge - $16
    Mech plug - $14

    So total about $170 or so. Hopefully this stops the 2-1 bump and prolongs the life of the trans [​IMG][​IMG][​IMG][​IMG][​IMG][​IMG]

    Update:. Dropped the pan and valve body today. Not too bad of a job, but it is messy. A few things to note:
    2008 lincoln navigator (zf 6hp26 transmission)

    The exhaust is in the way of the back 5 bolts so you need a small right angle wrench that can use a t40 torx bit. I bought a small kobalt set that had this small wrench included.

    The mechatronics/valve body bridge was not cracked but the seal was slightly warped. The 4 valve tubular seals all looked ok although they were somewhat crushed compared to the new ones.

    When you drop the valve body, more fluid will dump out.

    The pan gasket is what looks like paper and it matched my replacement exactly.

    All parts fit and looked identical to the original.

    Tools needed:
    T40 torx bit
    Small ratcheting wrench that can use the t40 bit
    8mm Allen key
    Oil catch pan
    Angled pick or small needle nose pliers to remove 4 sleeve adaptors
    Inch pound torque wrench
    Oil pump(had a cheap harbor frieght hand pump that worked great. $5-7 at harbor freight.)

    Takes about 2-3 hours if taking your time and allowing things to drain properly.

    I'll update if this fixes the 2-1 bump or not.

    08navigator was your pan gasket not steel? My 2007 Expedition 6R75 has an aluminum (metallic color) pan and a steel reusable gasket. I just cleaned and reused the gasket as FordTechMakuloco suggests.

    Do you notice any difference with how the car shifts?

    My pan was steel(painted black) and I had the green what appears to be paper gasket. This may indicate that the fluid had been changed before and they used the zf green gasket. I'm not sure. The fluid was dark in color but looked good still. It had a dark clear color to it if that makes any sense. It also did not smell burnt. I'm wondering if they used the zf lifeguard fluid in it since this does not have any red dye added I believe.

    I drove it immediately after changing everything and it felt about the same. I haven't driven it since so I'll update the thread with my findings after 500-1000 miles. My wife has pit about 200 miles on it since.

    The 2-1 bump was still there but much less pronounced.
