2019 S560 Transmission Performance
I have noticed that no matter what mode I am in (ECO, COMFORT, SPORT or DYNAMIC) I can never see the gears getting up to the 9th Gear or very rarely in D.
Some context before I ask your wise counsel.
- My commute to work (this is a daily driver) is about 25 kms each way.
- Max speed in traffic I get up to usually is about 85 kms/hour (56 to 58 miles per hour).
- In town I appear to be using a max 5th or 6th gear.
- On the occasional long trip (60+ kilometres) to the airport I get up to 8th gear when doing 100 kms/hour and see an excellent 7.9L/100 kms consumption. Otherwise I usually average about 12.0 L/100 kms.
Q1: Is the transmission behaving as normal or
Q2: because I have been driving it gently (only been in sport mode once and never in Dynamic mode) should I get the upshifting / downshifting checked and perform an adaptation reset ?
Q3: Does the old procedure of performing a home adaptation reset (as per the old 7 speed transmissions, key at turn 2, accelerator pedal to the floor, wait 30 secs, switch of, don't open doors etc etc etc) work on these new 2019 W222 9 G Transmissions ?
Q4: Does the 9 speed really need autobahn speeds to get up to the 9th gear ?
Your thoughts much appreciated.

In summary: the advantages of the new transmission are mainly gained at very high speed that the 8th and 9th gear are covering. The 2nd one is that 9G transmission can skip multiple individual gears when downshifting (which can occur only when you are racing or on a kick-down!. People think they'd get tremendous differences, but unfortunately the two gears have the same housing and even same size, and improvement is focused on two areas that are rarely used by the average person so don't be surprised that you are not seeing the 8th and 9th gears under normal driving conditions.

Between 80 to 88 km/h is in 8th gear.
Thats just a guess but maybe your gearbox received a different software then my pre-facelift model.

The engine is most efficient at 1,500 +/- 100 RPMs in converting fuel into mileage.
