Hello again, so I called bavauto today and told them that I'm going to change ATF and already purchased Febi bilstein fluid from them, but need more. They said that they need two weeks to get Febi bilstein, but they have ZF LIFEGUARD in stock now and it's ok to mix it with. I have a GM transmission and my question is if it's ok to use 6 litters of Febi bilstein for the first fill and drain, then 6 litters ZF LIFEGUARD for the final fill?
