Weird transmission leak!

Sent from my Lumia 710 using Tapatalk. So my 04 Yukon Denali has developed a noticeable leak from inspection holes on bell housing. Here's where the weird part comes into the equation. It only leaks when you start it when it's been parked a long time or the transmission is cold. There is a stream coming out both inspection holes and only for 10 or 15 seconds then stops completely. If I park it overnight I look under and no fluid on the ground, and feel inside the bell housing and no signs of fluid.

Front input shaft seal or oring on the input shaft.

I hope so. It doesn't sound to difficult.

Mine was the input seal. AER (who I bought my trans from) is replacing the whole trans under warranty.
