    LONG story short. My 2012 Civic was recently rear-ended at high speed and the car is a total loss. Miss it dearly.

    New Member Introductions
    Hi, I bought a used 2015 Honda Civic and last night I found some green liquid under the car. It looks like it leaked from the transmission. It was enough to soak a paper towel. I don't know when it started leaking and how much oil had leaked. I could not find a dip stick to check fluid level...
