I just did a radiator change and I noticed on the previous radiator two ports at the bottom. I looked them up and found out they are for the transmission. When I changed the radiator there were no lines hooked up to them. The new radiator has the same ports with screws to install. How do I know if there should be lines going there or not? I bought this jeep used so I don't know if they were left off on purpose or not. I have a 2000 2.5 tj manual transmission
