I have installed a CMG gearbox in my D11, for some time now the 2. and 3. Step in a little bit. It almost feels in the hand as if the gear is fighting back and pushing the gear lever back slightly before it then jumps in. You can hear a slight scratching. But not very bad...not yet
... Which 75w-90 oil would you recommend for a change? And maybe another oil supplement?
Thank you very much,
