transmission compatibility? 1979 300sd to 1980 300d

hi, i have the excellent guide on how to replace transmission, and am about to try this with my dad. he has the transmission out of the parts car, a 1979 300sd, and the torque converter wouldn't come with it (broken timing chain so no turning over). before we take out the badly slipping transmission from my 1980 300d, we're trying to determine compatibility issues. any known problems?? any help much appreciated, thank you! -noah

WVO Coversion Miracle

I've been running WVO for over a year now on a competitors system. Finally i got fed up with both the poor engine performance and my secondary WVO tank with heat exchanger built in. (I was starting to get scum build up in the tank from the constant heating and cooling inside. I also have problems with leaks and the fact that it made the temperature of my trunk rise to over 90% after a few hours was getting to me). I pulled out the system and replaced it with a system from mercedessource.com and I get a miracle. The electric boost pump and sump heater supplied by mercedescource are amazing.

Boom, Coolant vapor all over inside the cockpit

I recently got an 85 300sd with an engine that only has 92000 on it. The car drove great till I heated it up on a 30 min trip home from work during the hot part of day. I was just about home when I turned on the A/C, ahh it was nice and cold, but at a stop light the engine started to make some strange vibration and a few minutes later coolant vapor burst into the cockpit (not very nice while you are driving). I got the windows down and pulled over and the vapor slowed down, but the engine temp started to get hot.

AC Part Time

1985 300DT For some reason the tach will quit working periodically, when it does the AC also only blows warm air. What is the connection and how can I repair it? You can stop, turn the ignition off and restart and everything will work correctly again...for a short time.
