On my 1990 240DL the other day the shifter for the auto transmission started slipping easily from gear to gear.
Rather than the old solid click between gears it now easily slips from R to N to D to 2 to 1.
On the way up it will easily go 1 to 2 to D but will not go to N without a button press.
Also it will not go in or out of park without pressing the button as noral.
It still seem to change gears smoothly as normal but just something wrong with the shifter to keep it there.
I removed the cover and sprayed some WD40 down to the shifter track to make sure nothing was sticking, but that did not help.
Any ideas?
