I have been reading old posts about gear oil, looked in WIS and found that the 400 108 247 according to eeuro used to be "referenced as MTF0063" which shouldn't be mixed with other fluids. My 99 was made in Sweden but has the earlier VIN number so I am not sure what gear oil is in my manual transmission. I read one post which said that the MTF0063 was red. I am wondering if that is true and what color the previous saab fluid was as I woud prefer not to have to flush twice. Any thoughts on this one?
