Transmission May Leak Fluid and Damage Control Module on Mercedes-Benz CLK320

Problem Description and Possible Solution

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.

Trasmission fluid pouring out tof the bottom
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.
module leaked as indicated by transmission fluid on the ground. replaced module with updated rubber o rings.
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!
Transmission won't shift to 2nd from 1st. Only manually..
as above, was quoted $3,000.00 for repair
Noticed small leaks under transmission pan. Connector was leaking. Mechanic informed me that there was a TSB put out by MB.
