[Maxima A34 05] the oil level in the gearbox is increasing
 

Hello!

So far, I thought that the maxima takes a bit too much of the engine oil.

I was after replacing the gearbox and oil in the gearbox.

Currently, the oil condition in AT is increasing successively. Is it possible that the engine oil gets into the box?

Do you know if I am able to replace a membrane or something similar that causes a leak?

Thank you for your answers, this is my first post. My English is not very good.

by gear box do ya mean transmission or engine?

Gearbox = Automatic Transmission (for me :D )

Does it only increase when the engine is at temp?

I know that after warming the oil increases its volume.

Let's assume another case.
We check the oil - it's in the middle of the scale. On a cold engine.
I drive 1k miles.
Then after the night I check the oil in the box on the cold engine. Is max an dipstick HOT scale. Oil is cold!

am, of course, topping up engine oil while taking mileage.
