I will second that outlook and used the redline D6
The Redline D6 took all the notchiness out of the manual on my 325 xi.
I don't usually think that snake oils and additives are a good idea,
but this is something that really works. Now the transmission approaches
the buttery smoothness of a Honda Manual. I also put Redline in the old Integra manual and it brought it back from near death to near factory perfect after 230k .
