YOU NEED A DISCONNECT TOOL TO RELEASE THE LINE FROM THE FITTING, THE ORING IS REPLACEABLE BUT IT IS PAIN TO GET OUT OF THE FITTING. NAPA SELLS THE REPLACEMENT FITTINGS THAT ALREADY HAVE THE NEW ORINGS INSTALLED. THEY DONT COST TOO MUCH

I am losing transmission fluid but can't find a leak????? where can it be going


I take it that it is an automatic transmission, if it is draining that much fluid a month and you can't find any outside leaks it could mean there is an internal leak somewhere. If you see a pink milkshake color in your coolant then it could be the radiator transmission cooler which I believe wont cause an outside leak so you can start from there. It is located and is part of the radiator. Just follow the transmission cooler line and it will lead you the possible problem.
