I dod not have your model, but a 1976 300D, and I had shifting problems and low acceleration . There is a shaft with two adjustable nuts and threads running down to your throttle cable, I noticed when I put the accelerator down, I did not get any movement of the throttle linkages for 3/4 of an inch, so I tightened the shaft using the shaft, loosened the nut, and wound the ball clamp down about , well almost a half inch, man the transmission starting shifting normal and the car accelerated so much better.
I think it is that vertical shaft just to the right of your aircleaner intake, try that, and have someone move your throttle whilst your watching the linkage to see if you need to do all this.
