Thanks, Mike! I didn't know that about engine vrs. gear oil.

And don't I remember Bill B. saying something about Red Line...?

This is great timing for me, also, as it's time to change the trans
fluid. I've always used Castrol TWS Motorsport 10W-60 from my
local BMW dealer.

I'm gonna be in for a bit more work: with my lowered car,
my drain plug is ground flat. I'll need to cut a pattern in the plug
and avoid the fluid that's going to drain (top/inside of plug is designed
hollowed out) and replace with a new plug. Any other style plug to use?
The stock one sure has thin walls. I hope I used anti-seize on it.
