I am looking to find the location of any relays associated with the transmission. I have a 2002 A4 Quattro 3.0. it has recently rained 4 days straight and while I was driving(stopped at a red light) I started driving again the the transmission would not up shift to 2nd. I then noticed that in Drive my panel shows 54321 with only 1 highlighted. I put the car in Man mode and still the same. The car seems to work just fine in Sport mode, shifts automatically to all gears. I have checked fuses and opened the ECU box and no water in the box. I am stumped at this point. Does anyone have any thoughts on how to fix. Thanks
