Gear Oil for Tranny
Question... On my 84 truck, all the manuals call for gl-4 gear oil in the tyranny. I called the two dealers since I can't find it at the local parts stores and they told me to use gl-5 because that is what they would use. Should I just order some Redline MT-90 and be done with it? If so, does anyone have a good source for it?

Have also found conventional GL4 oil at local auto parts stores. Usually StaLube brand in a gallon jug.
