Hi, guys I am new to this forum..I want to ask about my w209 CLK320 year:2004 mileage:55000. I did some research on my transmission already..I found out that a lot of people have the same problem which is they NEED to REPLACE a new tranny for their cars (which I did already)..but the problem is still here..when the tranny shifts my car shakes(2nd to 3rd or 3rd to 4th gear), and sometimes it missed the gear from 2nd to 3rd gear ( heard the grinding sound)..since I did some research I followed a lot of peoples' decision - replaced a new tranny (MB dealer found metal when they took off the pan (from what I know is the torque convertor is already worn out so the metal came down))
Now, during shifting, the car still shakes or I can hear the grinding sound..the shop said they will try to re-program the tranny computer and see if it works fine..the warranty is expired and I am not a pro..I really need your help..I am really worried about my car..

Please help,

Km

 

When did they replace the Transmission? Did the problem get resolve after the transmission replacement and now is starting to reappear? You could have contaminated transmission fluid, this makes the clutches in the Torque converter too grab to much and not slip. The contamination comes form the radiator transmission cooler, it develops small cranks and antifreeze mixes with the transmission fluid.
