Dexron III is a specification for ATF oil :)

I recommend you these oils:

for Diff: Castrol SAF-XO or SAF-XJ (for classic diffs - no LSD)
- specs: 75W90 or 75W140 - SAF-XO or SAF-XJ meets all these requirements.

for engine: M20 engines (little six) - 15W40 oil or 10W40. (15W40 is recommended by BMW for M20s

M40 and M42 engines: (318i or 318is, also E36 318i etc.) - 10W40 or 10W60 (for racing M42s)

Tranny: Dexron III spec. ATF fluid or 75W90 common transmission oil.

Beware - the ATF fluid is very washy, so an old and worn tranny will be noisy. But gearchange will be easy in winter, though...

Sorry, it was an answer for "RigsPGT" who has a question about oils for an 325iX.
