Thats a HUGE difference from ATF. I didn't think that would work at all. How does it shift?

240D Four speed manual transmission. Dexron/Mercon III (ATF). I flushed out the previous thick sludge, three times before it shifted correctly.. In sub-zero temperatures, the previous (guessing) 80/90 gear oil prevented shifting, and/or gummed up the synchromesh = grinding in all gears. .

I'm thinking of going with Red Line D4 ATF in mine (82 240D 4 speed), but haven't decided for certain yet. I'm not going to be changing it for a couple weeks, waiting until it will at least be above 40 outside.

I used Mobile 1 Synthetic ATF and works fine. MUST smoother. I ran some cheapo stuff to flush it out (Autozone). Drained, and put the good stuff in. I think the Haynes manual indicates AFT, also.

I just refilled mine with Penzoil "Syncromesh". I have been satified with Dextron, but this is a newly designed oil for these constant mesh transmissios. I have heard good things about, so I am using it.

You can use a MB 235.1 approved 80W gear oil, but ATF was prescribed.
