2013 SL550 won't shift out of Park
I have a 2013 SL550 with just 45,000 miles and in excellent condition.
However, intermittently it will not shift into either Drive or Reverse or come out
of Park at all (certainly this is all with the engine running). Sometimes shutting it
off and restarting it will result in proper operation (that is, it WILL shift into Drive
or Reverse). Any ideas before I get it towed to the repair shop?
