[HELP] Transmission Oil Cooler Line
Today I noticed a coolant leak and after looking closer I saw it was a line that connects from the radiator to the transmission oil cooler. This line looks like this:
It is on the driver side. One end connects to the radiator underneath the top rubber hose (The really thick one) and the other end connects to the driver side of the transmission oil cooler. I think it's leaking from the rubber hose part but I'm not positive since it's all grimy. Do you think I can get this locally at Oreilly, Autozone, NAPA, or anywhere? I can't seem to find it but I just wanted to ask before I ordered the part.
EDIT:
I think it's called the Transmission Oil Cooler Line to Oil Cooler Line Pipe. I swear it's connected to the radiator though..

See attached for drawing of the tranny ccoler side of the radiator, and yes, you could have a coolant leak around the fitting that the tranny lines screw into. Being a copper and brass radiator, it can be soldered up by indy rad shop. I had a similar leak. Inside those lines is ATF at 100 PSI +, so if you see coolant (and no red ATF fluid), it is not the line or any O-ring associated with it.

Tranny fluid at that point is under pressure, per past rebuilder "Higgs Bosun" and others. At 100 - 150 PSI, vs maybe 10 - 15 PSI of coolant pressure, won't be much of a fight if tranny fluid is squirting out. Now the tranny cooler section of the radiator is inside that "tank" on the driver's side. You can remove rad, take to small indy shop in your area (look for one that does truck, bus, construction, and farm equipent). They can re-solder it, actually un-solder the tank, to work from both sides, and while you are at it, hot acid flush and rod out old calcium from well water and tap water used by previous owners. Should be less thatn $100 carry in. Don't drop off at Posh Radiator Shoppee, Inc,; where they price by the msrp of the vehicle.
