What do I have to do if I got a lot of water inside my transmission?

What is your question?

You have to manually shift my tranny cuz somebody put a new one in and they rigged up a metal wire that is going inside the pan and it is loose and means no gasket is on the pan. Now I drive thru water and all it does is bogg down and has no power at all. The o/d light keeps blinking now since I got the water in it. What do I do to fix it?
