In november I got my 55AMG and I love it. I sold my SLK 200…
The car was cheap couse gearbox (7g tronic 722.9) was damaged. The transmission tugged but in strange way. The gears changed smoothly and from the beginning I thought that the problem is in the clutch and not in the gearbox. I wanted to solve the problem. Unfortunately - the mechanic wanted to cheat on me, he said gearbox is destroyed, so i swapped it and I stayed withe the problem. When I changed the mechanic which is unfortunately very far away, he solved the problem. In the settlement, he accepted my old gearbox, which was in parts. He said that my original gearbox was in perfect condition and made no sense to change it
. The problem lies in the clutch. He swapped the torque converter and put one from S500. He solved the problem!
During going back home from mechanic (about 400km) when I pushed full gas, and 3 gear, sometimes at 2 gear the the clutch suddenly pulled off the connection.
This situation was repeated sometimes for about a month. Suddenly, something broke down. When I drive smoothly, everything is ok. When i push gas stronger - the drive system is disconnecting, the car is not going, only engine speed is incerasing. Than, gearbox put 5th gear and it is the only possible gear till I turn off the engine and start it again. Sometimes, even when I drive smoothly, the drive system can disconnect. It looks like the power of the car was to much for it. I'm not sure but the car is modified probably. The seller said the SLK was modified for 420 horsepower. Anybody has any ideas? This fault is different from the last one when the transmission tugged. To strong car destroyed another clutch? Is it possible to mount stronger torque converter from SL55 AMG with 500 horsepower? Does this part fit?
