I have a 2008 Ford Mustang that I noticed is having a small transmission fluid leak.. I added more transmission fluid.. from the looks of it the leak is coming from this black box looking thing on the underside of my mustang.. and I’m having a problem figuring out what the actual part is.. so I am attaching photos.. if anyone has a clue will you shoot me some ideas?? This is my mystery part I was wondering if anyone had a clue what it is??
That is the HO2S (Oxygen sensor) connector box that runs under the transmission. It is electrical in nature and absolutely NOT the source of your leak: http://iihs.net/fsm/?d=248&f=Transmission.pdf
The overall look of it seems to be coming from the input shaft seal or perhaps the torque converter... somewhere in the bell housing... can't be sure, picture's are a little less than helpful in pinpointing. I'm afraid that the trasmission is probably going to need to come out to find and solve the problem, 'cause something definitely has let go.
Welcome to the forums! I'm sorry to not be bearer of better news... but I hope that helps nonetheless.
Turns out the leak is coming from the transmission fluid filter gasket.. I replaced the fluid filter & gasket, & added 4 quarts of fluid to replace what was removed when I dropped the pan & removed the filter.. I also needed to adjust the gear selector cable linkage & TADA! No more problems.. I was just curious what exactly the box was.. Good to know it’s the Oxygen Sensor a Connector Box.. I appreciate your help for sure!!
And I’m happy to be a new member of the forum!! I absolutely LOVE my mustang.. She’s my baby... 😁
