Redline d4atf in manual tranny?
hey everyone, so what is the difference between REDLINE D4ATF, MT-90 75w90, and MTL 70w80 for the manual transmission? My car 2000 328i mileage is at 167,000. I am already going to put 75w90 for my differential, but just wasn't sure what to put in my manual transmission. DAVE from redline told me he recommends putting the D4ATF in there. What do you guys think? Any positive experiences? If it helps, the climate over in my area is starting to get cold every now and then.
