We replace at least 2-3 cables a week at dealer.
The cable can be replaced W/O removing the valve body, just like earlier cars. Takes 2-3 HRS
On the C-class we always remove the exhaust system.
You need to disconnect the cable from the accel linkage first.
The 2-3 shift must happen between 26-30 MPH for the computer to see the correct RPM.
Adjust the allen counter-clockwise to hold the shift longer(higher RPM)
