Car is a 08 legacy none turbo with a 4eat trans
I replaced the internal filter not the external one yesterday with about 4 qts of new fluid. Pan looks good but does have a very little dent on the external filter. At oil light flashes none stop and won't go away for nothing .
No noticable wire damage but not sure where tcu is I think under dash by steering column and I followed those as well look ok.
Got car from my dad which is original owner and he had it maintenance at subi deal for life of car. Car did sit for about a yr. He's had all done to it heads belts trans serviced and so on. Really confusing me. Really all this happened when a trans cooler line was leaking and we just cut where it was leaking and ran rubber hose instead of the metal rusty line inside the engine bay to the radiator. Since then the light has flashed like crazy. Thx
