Transmisson leaking problem

Hi,yes there is a fix,but first we must identify where the leak is,since it didn`t leak proir to the exhaust installation,it was likley caused by something getting bumped or moved maybe a cooler line nut?>best thing to do is put a clean piece of cardboard down under the car and takenote where the fluid is escaping,front,rear,left right,then you can make the corresponding repair,good luck.
