Darn thing is still leaking. There is already a small puddle under the rear of the transmission.

The leak originally started when I removed the drive shaft to have a new u-joint put on at the back of the drive shaft. Now I've replaced the transmission's rear seal and it still leaks.

I read that some transmissions have an o-ring inside that can be replaced which requires removing the extension housing. Could that be it? Wouldn't the rear seal stop any fluid leaking past that o-ring? (The slip yoke does NOT have a 'weep hole')
