My guess is, it puked out some fluid when it was stuck.
Back in the day, all antifreeze was green. So if you saw fluid, you knew what it was, by color.
Today, if you see red fluid, you don't always know whether it is antifreeze, or transmission fluid.
If you want to know bad enough, you can tell by tasting it.
On the other hand, anyone who is dumb enough to go slow, and let their vehicle bottom out, and hang up, going over a little snow drift, probably doesn't know that test. :laughing:
