Hi all,

I have a 2014 Cls 63 amg 4 matic.
Could you help to provide info on what are right spec for Front Diff & transfet case fluid?

For diff I have purchased 75w140 Castrol edge limited slip diff fluid got MB approved

Thanks for your help in advance

Hi,

The rear differential takes the 75w140 diff fluid however I have heard the front differential takes the same fluid as the transmission? :-/ I feel like this has been covered on other posts though.

When I did my front diff less than a year ago I believe from my research I found it took regular diff fluid, not limited slip fluid or trans fluid as the viscosity is too low on that. I put in 2 bottles from Autozone of Mobil 1 75w-90 gear oil.
