Fluid level for '80 300TD

I have a newly acquired 1980 300TD and the first thing I wanted to do was change the transmission fluid. The stick was reading 2 or 2 ½ inches above full at temperature before I did anything, but outside of some issues with the 3rd to 2nd gear kick down, it was well behaved. The gasket was hard and the fluid was very old which is not good news, but the car has suffered fair neglect and I was not too dismayed. The issue of immediate concern was that I retrieved only 6 qts. of fluid from the system, including torque converter. At present I have replaced the fluid to the level I found it at, but am not driving the car. I might guess that the dipstick is either a mismatched junkyard replacement, or maybe the dip tube has been modified or maybe the AT fluid was overfilled.

79 300d transmission issues - flaring/misengagement

Just want to verify these issues are covered in the new guide for pre-80 transmissions...just had the transmission throttle linkages adjusted and added the recommended LucasOil. After a few hundred miles, the transmission now flares between 2-3rd and redlines for many seconds before a shift from 1st to second (but only sometimes). It also seems to engage two gears simultaneously sometimes for a short time.

85 300TD Rear Wheel Bearing Race Problem

Have run into a real problem on my 85 300TD...apparently my right rear wheel bearing seized at some point, shattered the race (well, two pieces) and the new race won't press in (just slides in by hand...no interference fit.) Do I need a whole new wishbone back there? Kinda looks like it....can these even be had?

Given the rust issues...I'm wondering if it's time to jury-rig it by JB-Welding the race into the carrier to get the race in and relegate the car to short trips and focus on my W124.

Thanks.

77 300D Engine Transplant options

recently, my 1977 300D W123 diesel engine seized. Ive come across a 1984 300SD turbo Diesel W126. Can I transplant the turbo Diesel complete into my 1977 w123. I planned to transplant the engine, transmission, and rear axel.
Will this work? The reason Why I ask is because I am not sure if there is any wiring, or vacuum lines that wont interchange, or need to be added. Please advise. Thank you for taking time to help.

85 300TD a/c compressor won't work

I recently converted my a/c on my 85 300TD to R134. The system had a huge leak in the suction hose, which was replaced. The system was evacuated and I added three 11-ounce cans of refrigerant, but the compressor will not turn on. It was working fine before, so I was wondering if there was a switch or something that is not functioning properly, or if more R134 needs to be added.
