Looks like you bought a 2010 SOHC motor with a blown head gasket that someone tried to remedy by tearing out the guts of the t-stat! That NEVER works for long, as at speed the blown headgasket overwhelms the cooling capacity of the radiator. You were defrauded. Sorry. The AT light comes on perhaps the coolant temp doesn't square with what the ECM and TCM require. There's a small chance that the new t-stat you put in is undersized, and not the larger orifice OE size. So first get a Subaru-spec (can be aftermarket, as they've caught up) t-stat installed, and see if the AT light goes off. You may have to disconnect the battery for awhile to erase the memory of the event. Good luck, You'll need it as someone already brutalized the old t-stat to try to hide the overheating. Sheesh!
