Transmission Fluid Leaking Problems of Mercedes Benz E430

My 2001 Mercedes Benz E430 slips out of gear for no reason while driving. This occurs intermittently and with no warning . It occurs almost every day and in order to re-engage the drive gear I have to stop the car, put gears in park or neutral and then back into drive, sometime during this operation several times . I contacted a mercedes specialist and he showed me the problem. Apparently the synthetic transmission fluid leaks into the electronics of the transmission and is actually drawn up the wiring and into the electronic control module located on the top of the passenger side of the engine compartment. I have been personally shown the fluid and was very surprised that this was possible, but apparently the fluid contains metallic elements which are affected by the electrical charge in the wiring and actually pull the fluid up into the control unit. . The fix is installing a special plate inside the transmission to stop the hydraulic fluid from seeping into the electronics, this also entails replacing fluids and cleaning the electronic wiring and components. Repair cost quoted is about $900. Apparently mercedes is aware of the problem and I was told that this problem occurs in many mercedes autos including e class and clk class with this type of transmission. As of this writing I have not made any repairs.
