I have a 2001 Honda Civic ex was giving to us,but needed a transmission so we went to pull and pay and got a transmission and had someone install it. I checked fluids one day and it was full. We smelt transmission fluid one day and noticed a leak. I then checked the level and it was bone dry. I have been needing to add a quart every other day. I have basic mechanical skills. Is this something I can fix my self?
