I think there's a VOA of the BMW MTF-LT3 over on BITOG. It's thinner than D4 ATF from what I recall, closer to D6 I believe (at least the vis@100)

However, since it's 'lifetime fill' I've seen it speculated that it'll thicken over time so perhaps they start out with a thinner fluid with this in mind?
