A minor tweak to the list....

The 1985 California version of the W123 300DT has a 722.4 transmission. I was quite surprised when I first read this and had to crawl underneath and scrape the dirt off to read the number for myself: 123 270 76 01 722 416 02.

I drained the pan and the torque converter, got about 6 quarts out. Put 6 quarts in and will check it after going for a drive tomorrow.

My W123 car now has Mobil-1 in the engine, transmission, and differential. I'll report after the first of the year on any operational differences, including leaks, if any (none now).
