you are correct.... the two smaller lines are trans cooler lines. If your vx is original (those hoses original) it is posible you are small cracks at the end. each hose is only about 18" and has oem pressure clamps on it. I did replace ours last year. You can buy the hose at Napa auto parts (Trans cooler hose).

What color is the fluid dripping (redish, oil is Trans),
