    bsmittle, Not only do the dowel pins have to line up but the center shaft of the torque converter has two notches cut into it to drive the pump. Usually you line up TC shaft with trans shaft then slide carefully together till the shaft on the torque converter makes contact with the cogs of the pump. Then you turn TC till it slides together more then you engage dowel pins last. It almost sounds like the pump inside the trans had those drive cogs knocked off or the seal for the inside of trans shaft that seals TC is damaged. either way the trans and engine have to come apart.

    It would be hard to bolt up the trans and engine if the pump blades weren't engaged---I suppose you could force it by bending the flex plate.


    in any event, replacing the pump is no small job, if that's the problem.
