Have the fluid and filter changed first and see if that helps.

Change fluid and filter first like he said, but I'm afraid it sounds like the forward clutch piston is going...they were made of aluminum and are bad about cracking. Best thing to do is to have a shop rebuild the whole thing and replace the piston with a steel one.
