Not shifting
I currently own 2009 S550 4matic
Car wouldn’t shift so I did a reset using the gas pedal and ignition turn on.
Every thing is working fine but what caused this and should I be worried?
Thanks

[QUOTE=Cuzzo;8309639]How do you do that...mine doing the same..2011 s550 4matic[/Turn ignition to on position 3 right before you start the engine then press your foot on the gas until you hear the click it’s a button at the bottom of the gas pedal that allows the car to down shift once you hear the click hold it for 15 seconds the while foot is on the gas turn key all the way to the off position and let the gas go. And wait about 5 minutes. Do not have radio on or air on while doing the reset and do not open door just wait for the allotted time.
Start car and drive for about 15 minutes it normally takes about fourty shifts to go back to normal but car should be shifting fine before then. Let me know if it works my check engine light went off and everything after doing this and she was back to normal.
