Can someone help me solve my leak?

[masd]

Hi, my 320 convertible chromie (auto) is leaking transmission fluid behind the gearbox. In the second photos you can see red liquid droplets leaking out of what I think is a screw.

The pipe on the other pics is also wet. I am trying to work out what the problem is, but am not a mechanic by any stretch, so any help would be greatly appreciated.

Thanks
