The flexible bowden cable helps control when the transmission shifts. If it is disconnected or loose or out of adjustment, it will cause your transmission to shift too soon, thus making your diesel feel like it has no power. This cable attaches to the throttle linkage on top of the valve cover and is extremely easy to adjust. If you look closely, you can see this cable coming up from the right side of the transmission to the right rear side of the valve cover. Where it attaches, you will also notice a white nylon threaded adjusting shaft. You can turn it in to loosen the bowden cable or turn it out to tighten it. As with the pressure control rod on earlier models and various engines, you want the pressure on the bowden cable to engage just when the throttle starts to open. If you play around with the adjustment a little, it will become obvious how it works. Once again, you want the bowden cable to move "in step" with the throttle linkage - both starting to open at the same time and both reaching full travel at the same time.

Peace out.
