CLS500 7G tranny trouble
Hi.
Any experts on a 7G tranny that works fine, EXCEPT when doing kickdown. Car will shift down in gear, but then pops out in to neutral when hitting high revs, and tranny is still showing "D" mode. Engine off, then on, and car drives fine again. Oil and service is ok.

Hi.
How can you do that? No, transmission is standard. Everything works fine, manual shift, shift when accelerate without kickdown. Only mystery is going neutral in high revs AFTER a kickdown.

Actual values require Star diagnostic system hooked up while driving. You can watch and see what actually happens when it defaults to neutral. Most of the time it's a speed sensor issue, which is serviced in the conductor plate. Have you ever changed it?

Transmission Computer unit replaced
I had the same trouble with my 7G tranny on my Kleeman 2005 CLS 500, and it showed a valve unit error on the diagnostics system.
After replacing the Transmission Computer Unit and recoding it, the tranny works fine.
(quite expensive in Denmark, almost 3 K EUR for a replacement unit).
You should look for an error code regarding the valve unit in the gearbox.
Kind regards
