Question regarding transmission oil
So i am going to hand in my car to the autoshop soon to fix the famous "5th Gear Shifter Flop" problem and replace the bushing thats causing this issue. I cant live with this problem any longer. It's so annoying.
Anyhow... I am going to ask the mechanic to change the transmission oil while hes at it, and i asked my local BMW-dealer what kind of oil they recommended.
He told me to buy Castrol SMX-S 75W-85
But when searching i cant find any good information about this oilbrand, so i figured i could ask you guys if you have any experience with this oil or if you would recommend something else?
The car is a 330Ci -03 with manual gearbox
