[Shotimes] Redline D4 best fluid of choice for an MTX-IV with "paper" synchros

[Carl Prochilo]

No.  ATF is too generic a term.  Dexron III is an ATF.  The difference
with some of the other choices is they are synthetics.  Basically
analogous to motor oil comparison.  AZ apparently carries Mobil One ATF
and I picked 4 quarts.
So in the case of the 325i mentioned below, the factory is shipping their
cars to the field with synthetic ATF from the get-go.

Cheers,
