The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

Same happened to me... sounds like this should be a recall item with SO many reporting it! Got a great used Transmission computer from a Benz mechanic in Memphis... only $78 and clean! Don't pay $900-$1000!

The transmission shifts sluggishly from second to third gear when in Drive. Down shifting is also very sluggish. Tech at my repair shop discovered that the wire harness had the fluid in it, cleaned it all up and did a transmission service to replace the fluid, now we are waiting on the cost for the control unit. Hope that fixes the issue.
