1977 300D Loss of power while going uphill

I've heard that 77 300D is not a strong car to begin with, but mine actually slows down and barely makes it up the standard Washington state hills. At the bottom of a hill I could be going 40mph, and by the time I get to the top it slows down to as slow as 25mph!! So far I replaced both fuel filters, air filter, checked compression, compression is right about 330 PSI in all 5 cylinders, which as I understand is pretty good for this engine (or is it?). What else should I check or do to fix this? Any help or ideas would be appreciated. Roman

Transmission kicks down, won't upshift

I bought a 1981 300D, and replaced the old transmission with a working used one. At this time, the car runs smoothly, however the transmission kicks down into a lower gear too often/frequently. Instead of going into 3rd from 4th, it drops to 2nd, etc... It delays upshifting, lifting off the accellorator helps... Also: The dash lights, climate control, and radio do not work but the fuses seem fine... Any Ideas! Thanks!

240D crank pulley information

Traveling down the highway, I thought for a moment that the gremlin in my 240D (http://mercedessource.com/node/4065) had suddenly gotten chewed up and spit out the rear as, after the brief ruckus, my horsepower suddenly increased and the engine ran super-smooth. That dream was short-lived as my temperature gauge quickly pegged and I realized that I had no power-steering. After I pulled over and popped the hood, I discovered my crank pulley sitting sideways against the radiator, wrapped in a ball of belts and fan blade fragments. My question is this:
