leaking from bellhousing

The plug Zijmer mentioned that seals up where the front band lever pin goes in is the only thing that you can check or do anything about if it's leaking short of yanking the trans. If it wasn't sealed good or tightened good it can leak there. It's accessible (just barely) with a long 1/4" drive extension. Most have 1/4" square hole so the extension just slips right in but I have seen a couple that required a allen socket. If you pull the torque converter access cover you will be able to see if the oil is coming from the middle part (front pump/converter problem) or off to the side which would be the plug leaking.
