Review on Red Line Transmission Transaxle Lubricant by Darryl Duncan

It took about 15 minutes drive to get it working but my manual shifting went smooth much better than before. I have a 2012 Nissan Sentra S manual transmission. I read on some forums that you first need to remove the plastic plug from the wing nut and stick your finger in, feel for the fluid and I didn't feel it which told me it was quite a lot gave of it. I sprayed the drain plug with WD40 2 days before to avoid problems removing it and it was easy. A little over 1 Qt leaked, maybe 1.2. It was definitely low. I reinstalled the drain plug and using a clear tube from an aquarium siphon cleaner, attached it to the funnel and inserted the end of the tube into the filler plug area. I was pouring very close to 2 Qt until I saw it start to flow from the fill hole. I screwed it back on and went for a ride and I'm impressed. The Nissan owner's manual calls for 75w-80 GL-4 and also FYI I was annoyed with the recessed square for the drain plug and I thought 3/8 would fit but it DOESN'T FIT, even the stupid Nissan told me let it be 3/8. It's actually an 8mm square head which I bought here along with a 10mm head for 7.99. I couldn't tell that no one around me knew what the hell I was talking about.
