1979 CJ5 304 leaks everything!! Help

So, last week I discovered a trans leak, appears to be leaking from either the vent, or the trans/ tcase gasket. I pressure washed the entire transmission, and today to my horror I found antifreeze all over the bottom of the bellhousing. I checked all the heater hoses, they are all tight...any suggestions as to where this leak may be comming from? are there freeze plugs behind the flywheel.....I sure hope not, really dont want to yank the motor.
As always, Thank you all in advance
~Jim

A pressure tester works wonders....sometimes it is easier that you make it out to be. In the time It took me to write the post, I could have solved my issue.
thanks

James,

FYI, there are two freeze plugs behind the flywheel. You can see both in this pic.

So, where was it leaking?

It was actually leaking from the rear intake heater hose fitting, I removed it and just replaced it as I have a garage full of adapters and fittings from various projects. A simple fix. I borrowed a friends pressure tester, which I think I am going to invest in as I also found a loose hose clamp on the water pump also...kind of felt like a bonehead at the end of this. I also posted another question about a previous post you had commented on, why would that sucking exhaust valve noise go away with an increase of 200 RPM at idle? I increased the idle from about 600, 650 to about 800, and the sucking sound out of the passenger pipe is gone....Did I just mask the inevitable?
