    A 4L60E is nothing more than a later version 700R4. The rear of the case uses only 4 bolts to retain it to the adapter whereas the 4L80 is nothing more than a TH400 with overdrive which uses 6 bolts to retain it to the adapter.

    Well...seeing as how the 4l60e is a 700r4 electronic version....the pan should be a rectangle.

    And, the 4l80e pan, being a 400, should be a really screwed-up, un-describable shape.

    Found some pics:

    TH400 (not same pan as 4l80e apparently)...... [​IMG]



    700r4 (4l60e)..... [​IMG]

    My 4L80 is mostly rectangle with the corners knocked off. They dont look like a TH400 pan.

    OOPS....MADE A MISTAKE /forums/images/graemlins/ignore.gif /forums/images/graemlins/ignore.gif
    Summitracing listed it only as a pan for the TH400 - sorry, I guess I looked at it and thought...hmmmm, if it's a 400 pan, than it must be a 4l80e pan too. SORRY.
