Rear differential

I found two problems, 1 the return line from the trans cooler is where the leak is coming from, and 2 the end of the vacuum modulator is broken off so no place to hook the hose. Its raining right now so all of this will need to wait until it drys up. The joys of working outside in the dirt. Using carb cleaner I cleaned the side of the transmission and now can see whats wrong. I may need to replace the fitting on the return line from the trans cooler, I may have striped it the last time I was under there.
