I will guess that the problem is either the main fusebox is not receiving power or the Signal Acquisition Module (SAM) located beneath it is bad. The fusebox is easily checked with your voltmeter; the SAM is quickly and easily checked with Star Diagnosis. You can purchase your own SDS from Chinese eBay sellers for about $800.

I got it towed to a local benz mechanic, He is looking at it and I will let you know what they find. Thanks for the reply !!

update::: Good news on the car. Took it to the mechanic and he diagnosed it as a bad voltage regulator. The alternator was putting out over 18 volts to the cars's systems and the computer shut the tranny off as well as the lights and esp systems as well as the braking sytems. It set 7 malfunction codes. Crazy ! Anyway $60 voltage regulator fixed the problem and the car is back working perfect. Sweet !!!
