crazy you could ever put it into first at 20mph! I can't/won't do it over 5 mph. I don't think it's good to ever put the car in first if the car is actually already moving, unless your at a very slow crawl. I think you're car may be okay, esp since you put in the correct fluid immediately after the wrong fluid was put in.
