TH-350 Leaking problem
 

My car has been parked for about a month. I was moving into my new place and started the car and put it on the trailer. It was spewing tranny fluid all over the place when it was in gear, but doesn't seem to leak in Park or Neutral. I glanced under it and it seems like it is coming from the weep hole on the top of the tranny. What does this mean? What do I need to do to fix it? It was working fine the last time I had it at the track. I rebuilt this tranny about 5 years ago.

Thanks for any input and advice,

Travis
