My old ('02) Silverado got a leak in one of the transmission cooler lines. I got 2 new lines delivered but in the meantime put a splice in the line where the hole was.
Took a while to determine where the leak was - when that fluid comes out it ends up everywhere underneath! I let the truck sit for a day so everything could dry up, which helped me locate the leak.
It was right where one of the plastic holder clips was - which allows moisture to eat away at the metal.
Temporary fix.......
These are the two lines where they attach to the radiator. You can see corrosion on the lines.....
The new lines came in these huge boxes!
