Trans model is a 4EAT.Subaru's version of the Nissan RE4RO1A.I would go after the solenoids first.Codes are pulled manually on that car with a procedure involving turning the ignition key on,moving the shifter,key off,move the shifter,key off..etc.Thats how trans codes are pulled out of the vehicle,and it is an exacting procedure as prescribed by Subaru.That is the very first step,as diagnositc codes will lead you in the direction of the malfunction.However,those trans' are known for problematic solenoids,and i replace the solenoids with new on every overhaul i perform.The ones on your car should be click checked with 12 volts,ohms checked,and amps checked.If the solenoids pass testing,then likely an internal trans problem.Back to the codes FIRST though.As a final resort,before removing trans from vehicle,remove trans pan and visually inspect.If lots of metal,you have internal problem.
