I want to change my gearbox oil. I have a 350i with a suffix E LT77 gearbox. I have looked all across the web and it seems everyone has a view as to what is best! The Rover SD1 manual states Hypoid gear oil, SAE 75W EP (Recommends Duckhams Hypoid 75) or Type 'G' ATF to M2C 33F or M2C 33G for 'later' models (Recommends Duckhams Q-Matic)

I have no idea what a 'later' model is and the two types of oil are quite different!

What is the current recommendation?
