I have noticed that when put foot doon from stationary i have a short spell of what can only be described as wheel oot of balance rumble from rear.
Disappears when release acc pedal and when not present when not heavy on right foot.

I am about to "teach" gearbox my driving style although I have been told that my car/box ait that intelligent.

Any thots?
I think its a new box a few years back and I have not changed oil.
Equally I have not checked rear dif oil either.

Thank you in advance
