1980 240DD Transmission Rough at Start

I have a 1980 240D sedan with an automatic transmission. When I start the car and drive it first thing in the morning, the transmission shift from first to second gear is rough, it snaps my head when it shifts! However, once I have been driving it for about 15- 20 minutes and it's warmed up, the shifting from first to second is much smoother and about the same for the other gears. Is my transmission having a problem, or is this typical for a car of this age?

1981 300SD Low compression #1 cylinder

I finally got around to checking my compression and found (the car has 300K+ miles on it) all cylinders had 280-325 on the compression EXCEPT #1 which I checked 6 times with different crush washers and could never get over 160.

I'm thinking I need to recheck my valve clearances one more time. What else can I look for to try and figure the problem?

Painting of 1979 300 SD

I am in the process of having the car painted in another country and would like to inquire if you would recommend the one stage or the two stage process. Because I am buying the paint, how many quarts do you think I will need, using urethane medium reducer, plus activator. The paint being used is called Val-Spar. The 1979 300 SD originally used a one stage process and the vehicle will be striped of all chrome hand sanded as there is no body work to be done and the original paint is just starting to form small check marks due to the aging. Thank You

84 300D Towed 2 miles - trans wont shift?

I just towed my 1984 300 Turbodiesel about 2 miles at 20 mph without the engine running - After I got the engine started again, the car would not shift into 2nd gear. Does it ruin a transmission to tow a model 123 without the engine running? It has been very cold out (7 degrees F) and perhaps something inside the transmission is stuck. Anybody with any ideas on what might be going on with this transmission after being towed for that distance and speed?

1981 300SD Oil in alda line

I was troubleshooting my 300SD for low startup torque (I have already adjusted the valves, rebuilt the injectors, etc) then I went to the alda. I removed the banjo bolt from behind the turbo but it wasn't all that dirty. Then I removed the bolt from the side of my alda and engine oil started dripping out. I don't know much about this thing but I don't think this is right.

I saw one of these for sale on this site. Is this something a shadetree mechanic can change?
