    Thanks for the info Trannyman. This trans has 106k miles.

    My Reverse band looks really good I think, even better looking than the Forward band:


    The 2-1 Manual band had a "stripe" in the center and a sort of "bevel" worn out of one edge. I didn't get a pic of that, but I can. Have you ever seen that? I'm thinking of replacing it; infact I'm leaning toward replacement of all the bands, just to be safe.

    The 4th steels looked pretty heat-soaked:


    The input and second steels had a few small spots, but not like the third.

    All the input, second and 4th fiber plates looked pretty good to my untrained eye.

    The 3rd clutches were badly coned:


    And had some "chips" missing from the friction material:


    Apparently that's a trouble area, eh?

    Pretty typical except for third, must have got used a lot under WOT and was all stock! Your 4th steels are also very common and a reason I dont like Raybestos clutches especially in that area. A few years ago BW changed the design of them and added a lot more grooves to them. This keeps more fluid on the clutch as it is a lube problem that is causing the "leapard spots" on the steels and you dont see the problem near as much on the newer trans's
