It is not recommended to flush a transmission since it will move debris threw crew-shell parts of trany, no matter how well you do it debris will hang up in some nook or cranny. Just change the fluid and filter and add the Lucas treatment with it.

Adding the Lucas fluid before a flush would be wasted money as it would be flushed out along with the old transmission fluid.
