I bought a very very clean s420, 80K miles. no warning lights, everything works, seems very well maintained.
This is at an auction, so no driving was allowed.
Bought cheaply for $10K.
Car drives and upshifts very very nicely, like butter, all the gears are there.
In manual mode, no problems, all the gears are there, no delay or slipping on engagement.
However, in D, the normal drive mode, a down shift, from 3 to 2, or 4 to 2 is very very very hard.
from 3 to 2, it seems to engage 1st, and than forcefully execute 2nd gear. From 4 to 2, the same, it engages 3rd first, and 1/4 second later forcefully engages 2nd.
So forcefully that the wheels actually spin a split second, and the traction light comes on for a flash.
I did scan the trans for codes, I have a snap on modus scanner.
It did tell me there was a gear command problem, " desired gear inplausible"
The same for another code, "actuated gear inplausable" or tansmission slipping.
I am going to change the gear shifter in the console tomorrow, with all its switches .
Is this a feasable option?
