Hyundai Repair: Hyundai transmission cooler, transmission cooler, repair experience

Question
I have a leak in the Transmission cooler or one of the lines to it. Is this job doable by some one with a little automotive repair experience

Answer
Dear John,
       If it is a line leading to the Transmission cooler yes. Just get you some transmission sealant to go into your transmission, that should stop it.
