No communication with transmission Control Module

Asked by Oct 21, 2019 at 05:56 AM about the 2009 Mercedes-Benz C-Class C 350 Sport

Question type: Maintenance & Repair

I have a Mercedes Benz C350 It seems to be
stuck in gear not sure but seems like 2nd or
3rd and the check engine light is on. Also the
dash display which normally shows
PRND and C (which I believe is for cruise and
sport option) only shows PRND and the C
seem to have disappeared.

But initially when it happens I switch the
engine off and restart it which seems to solve
the problem for a while but the problem is
now constant also now when I put it in D or R
there is a little thump.
