OD leaking

I have discovered an oil leak in my OD housing. After adding some dye in the transmission and running around the block, I have identified a slow seepage of oil coming from a pin hole on the tail stock of my OD. To be clear, it is not pushing past the flange or any gasket. There is a small pin hole in the aluminum rear flange that is seeping oil. So how did I get a pin hole in the aluminum OS tail stock you ask? Beats me..

I have had this car for 11 years and have driven 45,000 mi with no leaks until now. So my question is what does the list suggest on how best to stop the leak. I can pull the tranny if needed but also have a clear line of sight to the OD as I have pulled the transmission tunnel off.

I had a similar leak from the bottom center of my gearbox. It was porosity in the casting. I drilled it out and tapped it for a setscrew (grubscrew) which I locked in and covered with JB weld. No more seepage.

Hitting it with a TIG weld comes immediately to mind...

yep, for a pin hole JB weld will fix it.
 
JB weld did the job! After draining the oil and cleaning up the hole so it was free of dirt and grease, I added a dab of JB weld to the Overdrive housing. The OD sat for 24 hours to cure. Then added new oil, went for a long drive and got it up on jack stands to watch for any leaks. I am happy to report the casing is dry, no drips from the OD.

Thanks for the suggestions guys!
