No forward power

I have a 99 WJ with the 4.0 liter. When the vehicle is put into drive or 1st gear the jeep doesnt move. When you give it gas the engine revs to about 2500 rpms before moving. Then it feels like a 3rd gear start on a manual would feel. Reverse works fine. It sounds like a torque convertor but them I would think reverse would be shot as well. The fluid is nice and pink and doesn't smell burnt. Any ideas?
