There is no 4X Low on a 4EAT.
I believe the 1st gear hold is electronically controlled.
Perhaps testing the switch would be a good place to start.

The TCU (Transmission Control Unit) is programed to force a shift if a certian RPM is exceeded. This puppy has many sensors and solenoids to control it's operation.
Let it cool off over night and see if it returns. Heat is a killer of these trannys, Subaru may have known this and that is why it has an over temp light (ever seen one on another make automotive tranny?) cross your fingers.
If a duty solenoid or other sensor has failed, the "POWER" light will flash upon start up. This is the TCU's way of telling you something is knackered. The FSM shows a way of getting the error code from the TCU.
You may want to post over on the New Gen board as they have many many more 4EATs than we old schoolers do
(thus the "put it in low range" comment)
A power flush of the tranny fluid would probably be an ounce (well few liters) of prevention but too late for a cure.
Sorry, you probably have not read this far, but I hope it explains some things.

although my 3at didn't shift even at redline when it was put into 1st gear manually..
i also know the old xt6 i had would shift if you pushed it hard enough.. and the trans temp light only came on once.. goin up a 12,000 ft pass with over 1500lbs loaded on the car (including 2 people).. this was prolly because it was so loaded the car didn't have enough power to get out of first gear, lol 10mph max speed (got passed by a geo).. let it cool off and it was fine..

I doubt it will leave you DIW (Dead In the Water) butya never know,
if the hydr. system pressure goes totally toast, you atleast have a knowledgeable service center to replace the unit.
As always, sorry I couldn't help and good luck
