First I'd be sure you actually have that "green stuff"...

By '02 ELC was more commonly used when assembled.

That makes sense. I took a sample and I can't tell. Is there a way to test the fluid?

When old, it may not be so obvious as Green or Gold. In my '02 I wasn't so sure either, I saw kinda "brown"...

It turned out to have been Gold (and gold is pretty crappy right out of the bottle) as I remember I was able to confirm it was by finding the truck was made at the KY plant (in your VIN). Trucks from there had stopped using Green by '02.
