Hi guys i was wondering which is the ideal transmission fluid for our c530 gearboxes? Instead of tutela technyx if we can change with something better.
Thank you

No I'm afraid not I do have the same c530 box and I was looking into changing the oil because I thought I had the dreaded M32 box but when I found out I had the c530 I decided not to bother so never got any further forward with the idea

Any oil of the correct spec will do

Personally I don't think gearboxes are are sensitive to the exact oil as engine's can be
Aslong as its the correct weight range and spec e.g gl4 for most modern boxes
