JB Weld on transmission oil cooler line(?)?

i was changing out the starter on my 4runner, long story short, cable from the battery arced out on transmission oil cooler line(?)(line from transmission to radiator) and made a hole in it. will jb weld work on it? how much pressure is on that line?(out of the radiator it connects to a hose with a clamp, off transmission it has a fitting)JB Weld on transmission oil cooler line(?)?
John is on the right track, but a split hose will leak.





Take a tubing cutter, and cut the tube. Put a piece of hose between the cut ends and secure with hose clamps.You may want to use a longer piece of hose, and double clamp it, but that will fix your problem.JB Weld on transmission oil cooler line(?)?
JB Weld won't hold there.





Clean it off really well about 6'; both ways from the hole.


Get a tubing cutter and cut it in two at the hole.


[Do not use a saw or grinder, those will get grit or chips in the lines.]


Lube the outside with some tranny fluid.


Slip a 2-3'; piece of rubber transmission hose [with an ID the same as the OD of the line - and I mean transmission hose, not fuel hose. Hydraulic hose would work also, it's really the same thing.] over the lines such that you have at least 1'; on both sides of the cut.


Then use a small hose clamp on each side of the cut.
Too much pressure for JB weld. Depending on the size of the hole, you could empty out your transmission in a hurry if (when) it ruptured. You might be able to have the hole brazed shut, but far better to replace the line.





You want a permanent fix, not a temporary fix that will fail when you least expect it.
No way would I trust a JB Weld patch on that. I would use tube cutters to cut out a short section containing the hole and then couple the ends together with a piece of reinforced hydraulic hose and hose clamps.
Get a piece of the same hose. Cut it longways on one side so that it looks like a C in cross-section. put it over the hole and secure it with a hose clamp, also right over the hole.
