I'll be changing the manual tranny fluid on my 2010 BMW M3 sometime soon. Fluid is a 75w80 oil. BMW recommends MTF LT 2 but I've also heard that's superseded by MTF LT 5. I'm wondering if anyone has any experience with one of these oils (OEM, Motul, or Fuchs)? The tranny seems a bit notchy with the factory fluid The motul is advertised as smoothing shifts so I'm thinking about giving that a try. Any opinions?
