I sent a parts link, showing the transmssion, Do you see the vent listed? All I see is the connection for vent hose, and this vent would be open and not need to be bled.??

It is a Metric allen wrench. Size is not identified! There is just enough difference in the metric wrenches, that it requires the exact size required. If you don't have the metric allen wenches, any auto supply carrys the assortment , and better t buy the setm that try to get the right one, without plug in hand! Sorry.
