It's the 5sfe if I remember correctly in my old GT-S. Anyways according to this theory...maybe/most likely? E153=camry and 5sfe=older camry, since the E153 fits the celica with custom axles/MWR kit; then it should be the same for the opposite. Overall you should have little modification to the transmission, except the axles. Not 100% on this theory. Maybe someone put input on this?
