but ZF Doc recommends either using GM Synchromesh (PN 12345349) , or the Castrol TWS 10w-60 you get at a BMW dealer
Yep, and 2 years ago the TWS was $22 a quart. I change to TWS at 65k miles and didn't notice a bit of difference, But there wasn't anything wrong with my trans anyway, shifts smooth,etc.
