I have the same Gearbox of the Renault Megane 2 and Citroen C4, i'm confused about the transmission oil i should use with it.
should i use Dexron 3, Mobil ATF 320 or equivalent oil or it uses another standard for the oil??
Does the owner's manual give a clue as to the appropriate service product?
Lots of modern MTs take ATF, it we can't say for certain for your vehicle without additional info. It may require a 75W oil or something else.,
