I am in the process of replacing all of the easy stuff (belts, hoses, plugs, rotor, lights, distributor cap, wires) on my new benz (1982 280e). Right now, I am working on vacuum hoses. It is fairly easy to replace the ones that are there, but some seem to be missing. For example, I know there is supposed to be a hose going to the transmission, but I can’t find one to replace. I see there is what looks like a vacuum hose fitting on the front end of the transmission, but nothing is there. Is this the right starting place? Also, where is it supposed to end up?
