When I moved my car out of the driveway this morning I noticed some fluid in the drive way so I got out to check it and YEAH it happens to be Transmission Fluid, I just had the transmission flushed / filter change and filled with some Amsoil fluid, in November. So the first thing that came to mind is maybe the Mechanic didn't tighten something snug enough and it eventually came loose. I drove the car around last night and everything seems to be shifting just fine. It could be a gasket or seal of some sort. How much do you think the repair might cost???
