[GD3-Manual]Like tabbed sound while running when gear kicks in

[vanishingpoint]

hi everyone,

I'm currently experience tabbed sound problem while my jazz start running with gear shifted in. I've tested by accelerate when i put it into neutral and this sound never occurred, it only happens when its moving (as in gear kick in). This sound is gettin louder during gear 1 or whenever i shift down. Has anyone experience the same as i did ?

Thank You.

Can you explain what you mean by 'tabbed' sound?
