So I bought a tranny cooler, strapped it on to the front of the condenser, ran the return from the box, into the cooler, and from the cooler back to the pump. Simple, right? Well I thought so. Then I filled it with more fluid while it was running to fill all those extra lines, everything was fine. Then when I shut it off it decided to start puking fluid everywhere. A LOT of it just started pouring out of the fill neck on the pump. What did I do wrong?
