Our patented pouch is easy to use in compact spaces, releasing 2X more fluid with less effort for 3X faster filling vs. traditional bottle packaging using 75W-90 Gear Oil. Engineered for hypoid rear differentials and non-synchronized manual transmissions, the full synthetic formulation and special additives protect from rust and corrosion while providing enhanced high temperature performance and cold temperature fluidity. With 30% better protection against towing and heavy loads, 1.5X stronger extreme pressure protection and 1.5X better gear wear protection vs. Valvoline Daily Protection 75W-90 in ASTM D-7452, it’s essential for demanding, severe-service driving as well as off-roading. Our innovative gear lubricant features a limited slip friction modifier for optimal clutch pack performance, an extreme pressure additive to protect gear teeth and prolong life, and an anti-foaming agent for better lubrication. Protect your gears with Valvoline, the #1 gear oil brand.

Review: Great design & product! - Perfect, used as a maintenance item on a 2019 Ram Rebel as the differential fluid on the truck needed limited slip additive. So far the fluid is doing its job with no leaks. I love how easy it is to fill the differential with the baggy design for the product, brilliant! Great value for the money!
Review: A superior solution! - Super form of gear oil / Hyundai 6 speed DTC transmission fluid. This gets around using and contorting tubes and gravity for fluid replacement. This saved a bunch of time. Not only that, but it was much cheaper than the Hyundai OEM oil and had better certifications, and although it costs a little more than other equivalent fluids, their use in traditional bottles is much more laborious and less efficient. This saved a ton of time, effort, and then clean up. Super!!!
