I just got my NV4500 filter kit from Geno's garage and wanted to ask which gear oil should I use for my tranny? I think I am supposed to use a 75w-90, but I am unsure of which brand to get.
Also, anyone running the filter kit I purchased? If so, what do ya think of it and how it performs? Nice that it supposedly makes the tranny hold about another quart of lube.
