Hi everyone,

I would like to service / change gearbox oil. Can I use another brand oil for example the Petronas Tutela ATF D3 gearbox fluid for the Produa Myvi 3rd Gen (D20N) 1.5 Auto. Do I need to flush gearbox oil before changing oil?, because I think if we change the gearbox oil, not all oils will get out. I'm worried that mixing oils from different brands could damage the gearbox.

I think you're better using the new Perodua ATF D3-SP fluid. It is an improved formula for newer gearboxes.

BTW, I think Perodua ATF and engine oil are blended by Petronas also.
