2020 Mercedes G63 transmission reset —anyone know the steps?
Good Day-
On my previous gen g63, I was able to reset the transmission (which I did often) to improve shifting and unlearn poor shifting...the process required a few steps but was done by consumer —not just dealer.
Does anyone know if the new Gen g wagons (g63) (2019-2020 models —-not the previous model years )have a similar reset sequence that We as owners can perform at home ?? The shift quality and shift strategies get worse over time —although much improved over last gen g wagons.
cheers

This was more popularly known in the past on here as the Sneaky ECU reset. It went to default factory settings before the adaptive learning took over for granny mode driving and gas savings. Some quick stabs on the gas will do the same thing but here it is if you can work around the push start button or it is still removable.
1. Turn the ignition key to the on (not start) position.
2. Press the gas pedal to the floor and hold for five seconds.
3. With gas pedal depressed, turn the key to the "off" position (don't remove the key), then release the gas pedal.
4. Wait at least two minutes for ECU to reset.

A gaggle of MB's
You can try the "Sleeper Reset" - I haven't tried on a new G - the other notes for this procedure to do it's thing - with your MB on and running - turn off all electrical (infotainment, climate control), shut down - open and close driver's door - and keep all dosed during the process, do the deal - and make sure you press gas pedal all the way down - hold for 15 sec - then release gas pedal slowly - then use a watch to measure 2min (I generally go for 4min so I don't have to repeat) - and in today's connected world that 2-4 min "feel's like" a hr !
Report back here what you find - if it reboots you to Factory Defaults - then your G will drive like the 1st day you got it - and heck, for most that's a leg up - as adaptive is designed to "trend down" from the defaults - adaptive does not "trend up" from defaults.

Delivery miles are just the type of driving to affect the transmission with gentle starts and easy driving at slow speeds. You should do the stationary or driving reset process before any customer’s test drive to put “some pep in the step.”

Folks, is there any M-B documentation that supports the procedure listed above? For example WIS/ASRA/EPC or Xentry? The steps given in this thread are the same as for a 2010 Volkswagen. The steps were ineffective back then. I am waving the "really?" flag.
