I saw on the VFAQ website it told me to not use kinds that said GL-5, but I cannot find the proper weight oils that are GL-4. It suggests some specific kinds like Redline MTL or MT90, BG Synchroshift, and GM synchromesh. All of which I could not find at Autozone, Advanced auto parts, or NAPA. The only gear oil I saw that was similar to any of those was Pennzoil synchromesh that said it was GM spec. but it didn't have any info on weight or whether it was GL-4 or GL-5.
