    We have a 2003 525iT (manual, sport package) and just turned 60,000 miles. I want to replace the transmission and differential fluids. Redline MTL seems to me the way to go for the transmission, but I'm curious about the differential. Does anyone have ideas about this?

    I use Redline 75W90 in all my diffs, it is fine to use in LSD and non-LSD diffs.
