The warranty on my 2006 ML500 expires in about six months. So I took it to the dealership to have them go over bumper-to-bumper to check for leaks or anything they could find to repair while still under warranty. They found and fixed a lot of things, but one of the most interesting was a software update for the transmission.
I have always been quite satisfied with the shifting. I guess I thought a slight surge from a standing stop and being able to feel the shifting was acceptable considering the that the vehicle was 4WD, had a stiffer suspension, and a fairly powerful engine.
The dealership actually did two software updates (one for the transmission and one for the engine control module). The resulting difference is incredible. My ML shifts almost as smoothly as the Lexus I bought for my daughter (which is the smoothest I have ever personally experienced). Huge difference!
I encourage all to have your dealer check your software next time you take your ML in for service.
what does your paper work show as the software versions?
