Wanted to bring this one back to the top..
Has anyone attempted this on the W140? I had a look at it this weedend and can say for sure that there are no bolts holding the shift lever in place. Alldata says to put the vehicle in "D" and tap on the lever with the palm of your hand at the same time turning it clockwise. I found this info. this afternoon and will give it a shot tonight. If this is way off and you know the right way to do it please let me know.
