removed the wrong transmission bolt, need advise < now with better pic

I was checking my gear oil and i took out the wrong bolt thinking this was the drain plug. car moved and it wont go back in. what should i do and does anyone know what i took out. I have added a much better pick of the bolt in question, notated in red. borrowed pic from another post. i need to get the part the bolt was holding on lined back up. i could really use a schematic so i can see how all the parts look inside to perhaps determine which way the part needs to move. if that fails i will have to remove the xmsn.
thanks for your help!​

So, called the dealer this morning and it is the reverse arm stabilizing bolt and I apparently have a lot of fun in store. I will try to line the arm back up and install the bolt before moving on to removing the transmission. if anyone has any ideas, tips or tricks i would be grateful.
