Possible Transmission Woes
Think about a person who, God forbid, wrecks their CL55 that has 30K miles on it. Unfortunately, these cars 'total' easily because of the cost to repair and their current values. Rarely do the major parts and assemblies of a car become damaged as a result of a collision. Inside that wrecked car is a low-mileage engine, transmission, and many other bits.
Really your choices are, in order of cost: a) Install a used transmission b) Rebuild your transmission to stock c) Rebuild your transmission and take the opportunity to maximize it's performance and/or durability with hi-performance parts.
EDIT: A large MB salvage yard nearby? Man how I'd love to have that available here!
