I've lost a good amount of fluid, searched, and found the leak behind the trans dipstick which was laying against the heater core outlet. This line( aluminum)connects from the coolant line and routes to the rear bumper. The hole is about pin size in diameter.
Question; what's the best, and longest, way to do a fix?
Would welding the hole work even with coolant present in the line? Would JB weld work?

----------

BTW way its not a Trans leak, it's a coolant leak. I tried uploading a pic,from phone, but the file size was too big. I will take one with a diff device

It's a heater core hardline, which is aluminum. It's the 2nd line in the pic

its near that connection so you could disconnect it at the T fitting slide a similar size piece of rubber hose on the end of the pipe and over the hole and seal with 2 hose clamps for a quick and reliable fix

Yeah I thought about that. Stealership wants, of course, wants to replace the $300+ ,part and then 4 hr labor. I put a JB weld type on and its good so far. I might do both.
