For me it was the mtf on a friends 2001 civic. This was a pet project of a shop that built race civics and came off of one with a turbo and I can only imagine it was the original fluid still.
When my friend got it i convinced him to change the fluid out and what we drained was absolutely shocking. Unfortunately i do not have a picture of this fluid but it came out a light grey green color and no light was passing through the fluid.
It was similar in shade to this:
