Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Reported by redwarts for the Mercedes-Benz CLK320

After having to add coolant several times, found coolant in oil pan when I changed oil in my Mercedes-Banz CLK 320. Mechanic said I need a new engine. Car runs fine. Can this problem be fixed? I don't have money for a new engine now, and I depend on this car. What do you recommend? Has anybody had a similar problem? Thanks for any help you can provide.

Reported by Doxiemom for the Mercedes-Benz C240 4MATIC

My C240 recently stalled twice within one week, Check engine light on only for a few minutes, then wouldn't start after gassing up. This car has scheduled maintenance up-to-date.
Towed to a shop 3 days ago. Seems like it should be an easy fix or not?
