I need help PLZ! Started leaking all my transmission fluid while driving on highway at 70 MPH. I noticed something wrong when I saw smoke from the runoff hitting the exhaust pipe and pulled over. I noticed that I was leaking "red" fluid pointing to transmission fluid. I am not fully experienced but it was leaking from passenger side up by radiator. Reading prior posts, but nothing related, The Transmission Cooler connection is in this area. If that is true and nothing else changed I am thinking its probably a hose? Where is there any way to tell and where do you add "transmission fluid" to this car. Towed car from side of highway. The prior symptoms we're nothing out of ordinary. The car is a 2005 Audi A4 B7.
