I'm glad this made a big difference!! More than you want to know about adjusting the linkage is here: https://www.startekinfo.com/StarTek/outside/12265/disc_2/program/Engine/617/30-300.pdf
This is really useful if someone has seriously messed things up and you need to get back to a base line. Note section C is where the 300D turbo is referenced. The biggest issues I've found is that you no longer reach the full load stop on the injection pump. That is, with your foot to the floor, you don't make it to the max stop at the pump linkage. Have a look at this, as it can make a big difference in the amount of go. As mentioned, the clunk can be vacuum. Can also be a flex disc which is sloppy. You can check this by driving on flat ground ~40mph... if you press and release the accelerator to load and unload the drive shaft and hear a clunk each time, then you have to look at the driveshaft/flex discs. If its really only on downshift, then its likely a vacuum leak. Jaime On Fri, Oct 4, 2019 at 4:32 PM Don Snook via Mercedes <mercedes@okiebenz.com> wrote: > The Bowden cable was sort of the issue.
