I am about to upgrade my gearbox from a zf5 to zf10, my old one is fine, but it has almost 3000 hrs on it. I change the oil every 100hrs or every month, whichever comes first. The guy at the gearbox outfit said that they are good for 1000 hrs, or less if bolted onto a 3 cyl Perkins like mine... So that means I will be replacing it after about 10 months.... That can't be right, can it?
