Want this question answered?
if you are asking about the cooling lines for the transmission that connect to the radiator, its easy. first disconnect the lines from the radiator (2 lines, usually on the bottom opposite the radiator outlet) then disconnect the lines from the transmission. remove the brackets holding them on, then remove.
I had a similar problem and ended up replacing both the lines and the radiator.
The best fix is to replace them they are available and not that difficult to install.
You need to replace the quick disconnect. Special tools are required to separate the joint without doing damage. Those lines are transmission cooling lines that bring the ATF to and from the cooler.
Cooling lines from transmission to radiator?
The 2 lines that come from the transmission and go to the radiator are full of transmission fluid and the radiator is what cools it.
Pinched or blocked transmission cooling lines
there are two metal looking lines that screw into the radiator that is the cooling side
The cooling radiator needs to be used to keep the oil from overheating. If the lines are plugged, the engine could be ruined.
if you have an automatic transmission there should be cooling lines going to the radiator to cool the transmission fluid the lines could be leaking or the tank could be leaking
These are HIGH pressure cooling lines; make sure you replace them with the SAME quality lines or they will rupture and leave you stranded. You often need a flare nut wrench set to remove them as they can be very tight. If they are just barely seeping I would not replace them ,but if in fact they are LEAKING then you need to update them.
They are on the passanger side of the transmission, They come out of the side of the trans and run up the side of the engine and hooks to the RADIATOR. Just follow the lines from the transmission. There are 2 of them.
