Plus important point, any knowledgeable MB specialist (/main dealer) should be able to 'adapt' your gearbox to your driving style/preference.
Professionally resetting automatic gearbox adaptations using STAR is very different in purpose, nature and proceedure compared to the often quoted adaptation reset procedure on Mercedes forums the world over. Whilst both refer to the word “adaptation”, they’re not related.
As you would expect, at the factory automatic gearboxes are set-up as a brand new gearbox, ie with no wear at all. As the car is used and the transmission becomes worn over time it constantly adapts those settings to take wear into account, so for example clutch pack fill times and pressures are changed as it wears.
However in normal use these adaptions are deliberately very slow to change over time, and so if a worn component in the automatic transmission is replaced - either due to being worn or damaged - then it takes a very long time for the transmission to adapt. A specific procedure using STAR is therefore used to do this following repair.
Personally I would therefore be reluctant to reset the adaptations unless there has been a repair already performed, as it could temporarily mask a failure of accelerated wear which should be investigated and replaced before it becomes critical.
This is a world away from what is wrongly described as resetting gearbox adaptions on forums, that is to put the key in position II, and hold the accelerator to the floor for 10 seconds. This is said to reset the transmission to provide the quick gear changes which Mercedes/AMG intended.
It doesn’t. It fools the car into thinking the car has been stolen and is being driven at breakneck speeds to evade capture and so it sharpens it’s reactions accordingly, despite the fact the car is sat on the drive. When the engine is started it takes the car a little while to realise that it’s actually going to Waitrose rather than being chased by a Police helicopter and softens up again.
The gearbox does adapt to the drivers inputs and does this much more quickly as evidenced by the fact that 10 seconds at full throttle is enough to trigger it, and a few normal shifts is enough for it to adapt back to normal again, once the driver drives normally and not like a joyrider. The word adaption is used but it’s not the same thing.
