Welcome back to 2CarPros. That sounds like front pump failure or a band failure. They also have had an issue with the sealing rings but those usually show slipping first.
Either one means pulling the transmission for a rebuild or replacement. Because these transmissions are fully mechanical there isn't something like a solenoid failure causing it.
You might want to check the fluid level just to be sure it isn't something like a failed cooler line, but usually that would create a big puddle that you would notice.
That should have either an A727 (most likely) or the A904 transmission.
