Need Help with 6L80 Transmission Cooler Lines Diagram!

Make sure to wear protective gear while working with these lines! Last thing you want is a surprise when you cut through a line and it sprays everywhere! Safety first!

Haha, true! Nothing like a little shower of ATF to keep you on your toes. Staying dry is definitely a plus!

Does anyone have a source for replacement cooler line kits? I’m contemplating changing all mine out since they seem to be original.

I got mine from a local auto parts store. They can often order specific kits if they don’t have them in stock!
