EDIT: Realized thanks to taking to time to read the video description that this won't apply to my tranny. Just found out after some online homework I have the 722.424. Jumped the gun and thought I was watching instructions for the 4 spd, it's not. The 722.6 is a 5 speed.

I really should not watch things like this when I'm tired....

I'm having hard shift issues occasionally on mine, and I'd like to correct it. If I can't I can live with it, but was curious. And are the 722.424 shifts controlled by the ECU?

No, your shifts are vacuum/hydraulic powered
I forgot how to solve your problem, be doing some searching later.



Ok, found some info from Benz World, it's a little bit to read but might help.
Majority of the info here. (http://www.benzworld.org/forums/w202-c-class/1380730-transmission-lurching-2.html)
Down the bottom of the page is a download link for a diagram of the transmission control module(Bowden cable adjustment) (http://www.benzworld.org/forums/w202-c-class/1430653-c200-w202-automatic-transmission-problem.html)

I did it, It has transformed the car off the line. The lady I bought it from never exceeded about 40 MPH so it was in top at about 1200 rpm. Kickdown from fifth to fourth still didn't fond the torque curve and was lazy. It isn't now and drives properly. Big thanks!
