Hello, New member....my daughter returned to our city after almost 5 yrs and so I once again get to work on her Mustang. Has just over 97k miles on it and has been problem free for the most part...but now it has a trans leak and I have not been able to determine from exactly where from. I think it is the tail housing output shaft seal. I cleaned the tail housing, then went for a short drive, got back under it and the tail housing again has an oily film coating. Just not sure if the oil is leaking down from the shifter area, the speed sensor, or is indeed the output shaft seal and the oil is just being blown/thrown forward when driving. Hopefully someone here has been through this and can tell me. Only thing I know to do would be to get the Mustang on 4 jack stands and run it, watch the trans to see if I can see the where the oil is coming from. Thanks in advance.
