On the vac to transmission leak - the leak is between the green metered valve in the engine comparment and the transmission. I replaced the small connector tube on the B-1 (or B-2?) and the volume of leak(?) - the speed at which the vacuum needle fell to zero on the guage - decreased.

I will probably have it replaced by a mechanic since it is twenty five years old and everthing I read says they don't last that long and I am afraid of entering an automatic transmission with two left feet. I am assuming that is what is causing a flare between 2-3 and 3-4 shift points. (It works well when manually shifted.)

I found the part number for the vacuum valve part of the ignition switch on another page - MB #0004600284, cost between $25 and $30. Difficulty of repair is questionable, they say it is iasy once you get to the valve.

Time I went and took another look at taking the instrument cluster out and what all I gotta fix there.

Thanks many time to all.
