I did some googlin' and this appears to be a common issue.

The Bad News - The root cause is an internal transmission seal that dries up and shrinks thereby preventing proper pressure buildup. Probably a $4.00 part, but you have to tear down the tranny to replace it.
The Possibly Good News - Some people have corrected the issue using a product called Trans-X.
