You need to get a vacuum gauge. Connect it to the brake booster hose. You're looking for 25-30 in/Hg. Check all vacuum lines for leaks until you discover the problem.

first you must find the leak you can either a spend $1000 on a smoke machine tester for vaccuum leaks which at first is a lot but pays for itself overtime. Another way it to pick up a can of Brake or carb cleaner and listen for a rise or drop in RPM's if it changes you found your leak

Well you need to start by finding exactly where the leak is. It helps if you find a diagram of the vacuum system. Do a check on all the components and see it anything is damaged. Paying special attention to the vacuum lines running down to the transmission itself. More than like it is a loose or punctured line.
