Verso11 - Is it necessary to replace gearbox oil?

[Eliezer_m]

When switching from gear 1 to 2, I feel a jump.

It's hard to describe exactly, but it's certainly not a continuous transition.

And this is noticeable to car passengers.

The car has 76,000 miles.

I realized that maybe the problem was related to gearbox oil, but on the other hand there was no manufacturer's instruction to replace gearbox oil.
Does anyone know?

I had the same problem on my 2010 6speed gear box at 80k miles. Transition from 1st to 2nd feel a gear clunk or bump as you described.

I have replaced the oil and improved slightly. The clunk still there.

What I do now is to adjust my gear engagement style. When shift from 1st to 2nd I leave the gear lever in neutral for about 1 second before I push in to 2nd. This avoid the clunk noise.
