Reply to "What is the best ZF transmission oil to use in a 1974 Pantera?"

Lloyd is recommending GL4 because it makes shifting easier.  There is no brass in a ZF or RBT transaxle.  VP suggests that their gear oil does not harm brass synchros.  We should not buy GL4 based on it being kind to brass and instead that it makes shifting easier as Lloyd describes.  He says the hypoid additive works against our synchros.  I cannot be judge on this and will yield to the expert.
