Do yourself a favor..... save Shoebox's code list in your "favorites".....

The tranny codes have two different definitions... one for the A4 and one for the M6

DTC 83 = Reverse inhibit system (Either the connector is off the reverse lockout solenoid, or the fuse for the solenoid is blown)

DTC 84 = Skip shift solenoid circuit (Same as above, but for the skipp shift solenoid)

DTC 77 = Cooling fan relay control circuit (Faulty relay or blown fuse for the fan circuit)

DTC 63 = Bank 2 (right) Heated Oxygen Sensor (HO2S) Circuit (open circuit) (Loose connector, broken wire, faulty sensor. Switch the sensors side to side and see if the code follows the sensor = faulty sensor; or the code stays on the same side = faulty wiring)

 

so the only code that will affect performance would be 63?

 

Yes. But isn't it a little difficult to get it in "reverse"?

 

not really. i guess its a little harder than most cars but its always been like that
