So after a while of looking around I think I found the leak for my transmision. it was definitely coming from the top, I thought it was from teh speed sensor so I replaced it but nothing.

after I let it run I used a mirror and can tell the leak is coming from the shifter piston looking thing. Sorry not that familiar with the names. its a mustang 2006 with stock transmission.

Is there a quick fix to that? or just have to replace the whole thing? I keep adding fluid every 4 to 5 weeks.

Thanks and hopefully there is a fix for this. I just dont see an easy solution.
