05 Mercedes Benz S430 125989 miles - Bell Housing Oil Leak - $2,500 (Newcastle)

This car all the sudden got Transmission Fluid leak. Today, I got car jacked up and liked to change the Transmission Fluid and noticed the Transmission pan is dry, and the Bell Housing shows Oil leak, so it could be either Transmission Front Seal or Oil Pump Seal leak. The car is jacked up now in the garage with bottom shield removed so it is easier to exam the issue. I’m the 2nd owner since 2007. It just recently had steering rods replaced and Front brake rotor and pads changed. I kept all the maintenance records. The car picture took on 12/26/16 (will take another pictur). Will take a one once I have it moved to drive way.
