used saturn vue 2005

Had this car since 2005, always ran great. Recently drove it 3 hours in the heat and the transmission spit fluid out the backup valve. Had it looked at at AAMCO and they said I needed a new transmission. It is ok to drive short distances (I drove it home from AAMCO and it was fine, 2 miles) but don't want to spend the money to have it fixed. I was going to sell it for 99 bucks but the ebay listing fees are 60 bucks, so I will put it up at 159.00 auction.
