MT and Diff Fluid Change Help Needed

jdub486 · 05-29-2012, 09:14 PM

My 07 335i just hit 50k time. For for differential and fluid changes. I'd like to use redline fluids, but I'm not sure which ones to use:

MT- D4Atf, D6Atf, or MTL ?

Diff- 75w90 or 75w90NS ?

Car is daily driven and never tracked. Fluids never changed before.

I am getting ready to do this as well - and from the research I did it seems that most ppl prefer ATF-D4 if you go with Redline - which is counter-intuitive bc it's an auto trans fluid.

What about Royal Purple? They seem to be a popular choice as well. Why did you write their product off?

I haven't done research about the diff fluid so if you find out let me know!

Good read above. I'm going with Redline D4 ATF for tranny and 75w90ns for the differential.
