I guess I'm not the only one that's not very familiar with the three speed tranmissions. But, I did find out what the problem was.

I removed the drive shaft and the cap that plugs the hole in the slip yoke shaft was missing! I'm glad I noticed the leak before I burned my transmission.

I went to a local tranmission repair shop and the they just happened to have a new yoke. The owner said he's seen a lot of them lose the cap plug. Also mentioned that you can repair them with a freeze plug cap but you have to find the right size one and grind it down, etc.

Mine was pitted and had grooves on the surface so I just went ahead and bought the new one.
