It sounds to me like one of the planetary gearsets has failed inside the transaxle. I've seen this quite a few times in the past. I would take a fluid sample and check it for metallic debris. There is a small drain plug on the bottom of the case. Just drain a small amount, 1/2 cup or so into a clean, dry cup or other container and look for shiny bits. Sometimes shining a flashlight into the fluid sample will help. Please let me know what you find.
