So why use the word gearbox then.
It refers to the lack of a signal to the parts I mention in my post, there should be other DTC codes with it.
It is an informational DTC for a problem which has its own code and originates elsewhere .
I will not bother to point you in the right direction as you know that.

I was told that P0500 refers to 'Gearbox Speed Sensor' - hence using it in the title - but if that's wrong, obviously I didn't know THAT!
Please forgive my ignorance, what's DTC (codes?) and PTCM ( -- -- Control Module?) ??
At the risk of boring repetition, this all started with intermittent BAS/ESP, ABS & Check Engine lights, which led to 2 x ABS sensors being replaced (which did need doing) but then, after a visit to Chrysler, the (gearbox?) speed sensor was also showing as faulty.
Apart from the lights, the only outward sign of a problem was lack of cruise control.
The real problem seems to be it's the blind leading the blind (me and my garage) - they are doing their best with sometimes insufficient code-reading equipment and (as far as I can tell), possibly not getting full story from the Chrysler stealership who presumably DO have the right gear...
Except that P0500 (and as mentioned previously C1120 & C1142), relates to the 'speed sensor' which apparently is mounted on or near the gearbox.
But it will take at least two weeks for Chrysler to get one from the US, hence looking for a suitable MB equivalent.
So, if that's the right thing to do, can you - or anyone - help with a MB part # as it is not legible on the car, so the MB parts chap cannot be confident he would be ordering the right part!
He could just order the SLK32AMG part but it may not be compatible with Chrysler electronics, so confirmation of part # would seem sensible...
