isn't it when the "power" light comes on all the time means that the tranny is .....dying or something like that?>.i've read that somewhere before...not sure if that was here or in the ...owners manual...tha'ts where..
i dont know what you can do to fix it....maybe the tranny is dead already...???? might want to bring that issue into a subaru dealer (providing that they know something about the car)...
