Any other ideas on what to check on this? The only other thought I have is perhaps it's a new vacuum leak and my transmission is now acting up and bogging down on the shift pattern? I can sort of kick it into the next gear by quickly taking my foot off the pedal, then back on... it kicks in to the next gear, but the engine feels like it's "wobbling" or something?... not firing on all cylinders?....


Hi
If you 79 300D is the same as mine it does not use vacuum for the tranny, it use's linkage, The linkage can be adjusted.
