So I changed my manual tranny oil today with Redline MT-90 gear oil. The shop manual and owners manual states 2.83 quarts. When I was getting close to the end of the 3rd bottle, I watched the fill plug. No fluid came out after emptying the 3rd bottle. Since the manual states "Approximate 2.8 US Quarts", does this mean that I should add more until I see fluid coming out? I only ordered (3) bottles of Redline, since I had to order it online (nobody carries it near me). BTW, I tried sticking my pinky in the fill hole to see if I could feel the fluid, but I guess my finger is to big. Any tips on checking where the level line is? Should I add more oil, maybe another brand?
