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.

Mercedes-Benz ML430 Wire Connector on Transmission May Leak Fluid and Damage Control Module

Visitor, 2001 Mercedes-Benz ML430, 136,000 mi
Oil leaked from a faulty seal & wicked into the control module. Could not get a rebuilt part from MB, so installed a new one. Price tag: $1900.00. Also have very dangerous issue with BAS/ESB system. Looks like the Navi unit has a short, causing the benz to think it is encountering a hazardous road condition. It brakes and swerves itself, which is really bad when you are in traffic. Frightening.
