We're discussing the manual tranny fluid level... Not the engine oil or diff fluid.
Per this thread: http://www.m3post.com/forums/showthread.php?t=129886
it's 2.1l of tranny fluid.
I'm not disagreeing, but I want to make sure it's done right and I'm not driving around minus .6l of tranny fluid... Especially since I'm enjoying the M button and driving the car fairly hard.
