In my endless search to find an amsoil equivalent of the recommended transmission fluid for my transmission, ive come up with the conclusion that the proper oil is some sort of castrol/burmah mtf 0063 75W90 synthetic fluid, which is saab part number 400 132 213 (superseded by gm part number 12799117) or saturn number 21018899. if i am correct, then amsoil synthetic gl-5 75W90 would be a good equivalent. is this correct? another question is what color is the saturn fluid? the stuff in my tranny is red and amsoil recommends synthetic ATF, which confuses me and makes me think it has syn ATF from the factory.

can someone at least tell me what color the saturn fluid is, please?
