I'll be damned!
I have used Redline's D4 for many years in my Manual BMW trans. Redline's ATF works just fine in them.
I just posted my thoughts in Rikx1M
I would highly recommend Redline's gear oils. D4 or D6 in our manual trans and MTL or their gear oil in our diff's. I like thier fluids bc they are fully synthetic and they really make a difference you can feel in shifting!
