Coolant leak around transmission pan area

Hi!

My 85 380SE got the coolant leak around the transmission pan area. It's leaking slowly and I need to refill 1 quart of the coolant each week.
It's hard to see where it's leaking in the area and it's only leaking when I am driving.
Is there any hose there that might have broken and leaking?
Is this repair a do it yourself task?

Thanks for your help.
