Progamming Transmission

Question by posted 2 months ago in Mercedes-Benz

I have a E250 CDI 4-Matic with the G-7 Tronic transmission

The car run very nice, but I would prefer the gearshift to happen a little earlier. 

For example: Starting from stand still, giving moderate throttle, the first gearshift will happen at maybe 2500 rpm. To my view this is at least 500 rpm too high. It only make a lot of noice and not much happens (Because I gave only moderate throttle)

I would llike to have the gear shift at maybee 1800 or 2000 to achieve an even higher comfort

Is it possible to re-program the transmission to behave differently ?
