Yeah, thanks. Appreciate the input Texasgeezer. I'm a PAgeezer. Have read a bunch about the 210 delivery valves from various posts and sites. Job seems simple enough. My point, although I labored intensely to avoid making it, was my w123 is almost 40 years old w/205K miles and has had no such issues. Everything works, even the ac. This E300 @140K miles is a completely different story. Ac leak, hose is NLA, can't find one anywhere (was $300 when available from MB). Transmission leaks at the electrical plug, causing ATF to wick up into the control module (great design, that). Already rectified. Transmission selector module is wonky and needs replaced ($100+)
Just blowin off a little steam is all. Guess I was imagining the E300 was gonna be a newer version of the 240D. You know what happens when we assume......
