Transmission / Suspension Specific Aid

1984 300SD ATF level drops when cooled ??

According to the manual, the ATF level should be 5 mm below the low mark on dipstick when at air temperature. I imaging this is because hydraulic fluids expand when heated and contract when cooled. I have the opposite: my level is at the full mark at operating temp, then rises about 2 inches over full mark after it sits overnight. It's as if the torque converter is draining into the pan overnight. The transmission is fine and doesn't leak.

Anyone have any thoughts on this? Thanx.

1959 6 cylinder Sedan Manual Transmission Interchange ??

Hello, I purchased a '59 220S that had the wrong engine and trans in it (mid-70's model). I found an engine with Type Plate M180.III 180.924Z and rebuilt it. I believe the transmission that I used was out of a 190SL, I don't have the number with me. The engine very quickly revs to high RPMs and seems as though the gearing is incorrect. For example, the car seems most comfortable if I am in third gear by 25 mph. I was told that all Ponton transmissions are essentially interchangeable with minor gearing differences, but now I am wondering if I have a problem with this marriage.

'84 300TD engine shudders while in park ??

Ok. I'm having some trouble determining what is going on after I've driven the car for a while then place it in park.

I get 1-2 seconds of shudder, followed by the same of smooth idle. If the same thing happened while stopped at a light, I might think it was idle speed/fuel delivery related (and it may still be). And occasionally after a spirited run, the engine will shake pretty good when I come to a stop, but smooth out pretty quickly.

But when I put the car in park it's a very quick shudder without much rocking like I get when I just stop in drive.

Any thoughts?

123 wagon rear suspension

300td rear suspension very bouncy.
I have rebuilt the self levering valve and it seems to be working fine. I bought a set of used actuator balls from you and installed them. It might be my imagination but that seemed to help for a while but now Im back to the bouncing around when I go over any dips or bumps.
When I start the car it raises up a little and when I carry a load it also raises up. Any suggestions.
Thanks
Rob
