    There is also a inlet check valve just off the trans pump to the main pump. The trans filter has bypass valve, it's called a Fiter Relief valve.

    Key 10 is the output line from the tranmission pump. The branch by Key 11 is going to the trans filter. Not sure if "kicker" goes to surge relief, but it might.

    In attached picture Keys 22-27 are the filter relief/bypass valve.
    I think keys 14-17 are the surge relief valve.
    Both can be accessed from out side the tractor, no splitting required.

    i tore mine apart over the weekend number 10 like u said is the output from the tranny pump the kicker just hangs there right above the bottom of the sump it just pulls from right there and it has a ball valve that opens during suction from the front mounted pump mine was stuck shut
