HI All,
I contacted ZF in Frederickshaven Germany, and asked about this lifetime sealed for life oil rubbish. The reply was simple, YES we recommend changing the oil in your transmission.
So armed with this recomendation from the manufactures, I aproached motorplan. How can they argue with that? they then agreed to change the oil!
However, as a rule, they 'dont' change trans oil. So I was advised to make a bogus claim that im experiencing a harsh down shift from 2 to 1. There is a SB out on this and the fix is to replace the oil.
oil was replaced and box is now even smoother!
Anyone want to have their oil changed, just mail this man for support :
