All automotive radiators have at least two radiator hose connections. Some have a transmission cooler line, which usually has those two, much smaller and threaded connections. If you do not currently have the two additional lines, you probably either have an external transmission cooler or a manual transmission. In either case, you can usually use a replacment radiator that has the transmission cooler whether or not you need it. Just check your bolt holes to insure it lines up the same.
The tranny cooler inside the radiator went bad.
Replace radiator ASAP. And flush tranny fluid.
im not experience but i own one and on the radiator passenger side is two transmission coolant lines that tranny fluid runs thru the radiator and the others i believe are coolant lines
What vehicle? Most likely to radiator that cools engine coolant, if not then there is a separarte tranny oil cooler.
If you do NOT have an auxiliary trans cooler, then look for two lines that run from the tranny up to the lower part of the radiator. They screw into the radiator and are cooled inside the radiator. One line brings the hot fluid to the radiator and other returns the cool fluid back to the tranny. Crawl under and just follow then from the tranny forward. They usually run right beside one another. If you have an auxiliary tranny cooler the lines still run from the tranny but at some place they connect to a cooler usually located IN FRONT OF THE RADIATOR. I said usually. Some peopel mount tranny coolers in different places. An auxialiary tranny cooler looks like a mini radiator with the fins and all. There are two lines .......one is the inlet and one the outlet just like the radiator. SOmetimes I have seen the lines going from the tranny and the inlet line goes into the radiator, then comes out of the radiaotr via the outlet, then the outlet line goes to the auxiliary inlet line in front of the radiator and then from the outlet the line runs all the way back to the tranny. This way the fluid is cooled in the radiator as well as the auxiliary cooler. Finding the two metal lines that come from the tranny is the key and follwing them.
there could possibly be an internal leak in the radiator if the lines from the trans are going to the radiator pull the rad cap and check the coolant and also fluid also burns up and sludges up
Are you sure it is motor oil? It may very well be tranny fluid, check to make sure it is full and clean. The tranny coolers are internal in the radiator in automatics. If there is coolant in the tranny fluid it will look like milk, make sure you do not drive at all, till fixed and flushed
The smaller lines approx. 3/16" at the side of the radiator
Your anti-freeze is a Dex-cool anti-freeze. It is not compatiable with the green kind. It is a long life coolant which can last up to 100,000 miles. If you have to top off, do not add water as this coolant comes pre-mixed. Is there red fluid on top of normal coolant? If so you have a leak between you radiator and auto tranny cooler.
Cracked radiator end caps since the tranny fluid runs goes threw the caps for cooling that is the only way tranny fluid can get in the radiator
There are two transmission coolant lines the run from the tranny to the radiator. On eline is an inlet, the other is an outlet. The tranny fluid is run thru the radiator to help cool it. These lines are usually just bolted into the radiator. Get a FLARE WRENCH and you can tighten the leaking nut. BUT!!! If it is tight, take the bolt out and you will see how it is, wrap some teflno tape around the threads in the opposite direction from which the bolt threads in and then START THE BOLT BACK INTO THE RADIATOR WITH YOUR FINGERS to make sure you do NOT CROSSTHREAD IT! You can do this to both lines. You will get some fluid loss so try to keep it to a minimum so you don't have to add tranny fluid back into you tranny.
Because there are lines running from the radiator to the tranny, this lets the fluid flow through and be cooled so that it does not over heat in the tranny and cause damage to your bands inside your tranny.
