Gilly, I track the vacuum hose that runs from the intake manifold to the transmission. I assume that it is connected to the vacuum modulator. What must I do in order to get the transmission to shift smoothly again. I earlier check the Bowden cable and also the adjustable connecting rod. Both the cable and rod are in the proper position. In addition, the throttle control linkage did not need any adjustment because the plastic tips indicators both line up.

The first photo is the Vacuum Modulator, second is the bushing are these correct for my e420.
