    I was sweeping the floor and found this near where I was building my 2004R and found this

    Not as long as the rollers in the rear sprag and shorter than the pin in the pump.
    I had several boxes of transmission parts from my friend who passed away, so maybe not something I left out.
    Any ideas ?

    Could it be from item 518 shown here ?

    yeah...but was it left out during reassembly... or a spare part from inventory?

    Looks like it could be one of the rollers in the one-way-clutch. I don't know how accurately you
    measured, but I measured one from my inventory and got .3099 OD and .4018 long with my
    Mitutoyo ball mike.
