Mercedes-Benz SLK280 Rough Shifting of Automatic Transmission

(10 reports)

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.

it's suddenly rough shift with very high RPM... what should I do? -
Rough downshift 2nd to 1st especially when cold. -
Transmission made a loud noise then it completely failed. -
The check engine light appeared and it would not shift out of first gear. I was t able to drive more than 30 miles per hour after being stuck out on interstate with no warning. I had the transmission flushed and it cleared the problem for approximately 2 months to find myself with the same problem. Mercedes has this particular problem under their own manufacture that allows only them to provide the part and repair. With spending two bills and time to flush the transmission and still the same problem. I should have taken it to the dealer in the beginning. I love my SLK and would buy another even with the scheduled maintenance being a little costly. -
When driving around 50 mph and then suddenly having to stop it feels like someone has rear ended me the down shift is very strong. -
