All:
I will changing the transmission fluid and rear diff fluid along with a number of other preventive maintenance jobs next weekend. Anyway, I will be using Redline D4 ATF as per Redline instructions for the tranny fluid and 75w90 Redline gear oil for the rear diff. Two questions:
1. I'm a bit confused on which tranny my 04 6 speed zhp has--looking at Bentley, they list 4 tranny types: the Getrag, ZF, S6S420G and the GS6-37BZ. I'm trying to figure out fluid capacity and each has different amount listed. It is my understanding that I have the Getrag but is it the GS6-37BZ tranny found in the m3? Prob will get two litres no matter what it is.
2. Rear Diff oil capacity?
