Review on 🚗 Pack of 4 - Red Line MT-85 75W85 GL-4 Manual Transmission Lubricant by Maurice Morris

Great product. Nowadays it is very difficult to find purely synthetic GL-4 based on ester. None of my local auto parts stores have even a fluid with that spec. This product is exactly as specified on my Nissan. Gone is the jagged shifting, gone is the noise of victory in the cold. This liquid did exactly what I hoped it would. However, I don't want to give five stars for one main reason. Irregular bottle. Since the filler plug on my transmission is difficult to reach, I had to buy a transfer pump. Most hand pumps that you find at auto parts stores are designed to screw on top of a standard gear lube bottle. Neither of them worked with a bottle of RedLine. So I had to go to the hardware store and buy extra fittings and vinyl tubing to modify my pump since I didn't have a spare gear lube bottle to use. I used a 1 gallon washer fluid reservoir after cleaning to avoid contamination and I was able to attach my pump to it with a small modification. I put all 4 liters in this container and then in the gearbox at once so this is the end result it worked but it's very annoying. Why can't RedLine just use a regular bottle like everyone else?
