Adding a trans cooler
I canít remember which line mine was but start the engine cold and stall the converter (hold the brake give it some throttle) for a few seconds and one line will be much hotter than the other.
Thatís a for sure way to tell which line is from the transmission and which line is from the heat exchanger in the radiator. Obviously Iím sure you know this, but be sure no one is standing in front of the car, donít be inside your garage and use common sense so the fj doesnít lunge forward and hit someone or something.
