Great board here guys!

OK, I went out and bought a '91 300D turbo diesel, when I bought it had the typical issues, harsh shifting ........I have done searches and been reading up on this but now the questions start.

What does ALDA stand for??????

Where exactly is the modulator for the trans located?

Does a schematic for the entire vac. system exist some where? I have the manual on CD but can not find much detail on the vac system.....

Tips on checking out the vac pump / system, I have a mitivac, does the vac pump produce a constant level of vac or does it vary with engine rpm?

Thanks

Eric
