TRANS-O
Powerex TRANS-O 85W-140 GL-5 is a high viscosity gear oil formulated for hypoid axles, differentials, final drives and heavy-duty gear systems operating under high load and low-speed conditions. The oil is designed to maintain a strong lubricating film between gear surfaces and support reliable protection during demanding drivetrain operation.
Built with VISC ARMOR TECH, TRANS-O supports extreme-pressure protection, viscosity stability and surface separation in axle and gear applications. Its 85W-140 GL-5 performance level makes it suitable for heavy-duty gear systems where high-viscosity EP gear oil is recommended by the vehicle or equipment manufacturer.
TRANS-O is suitable for workshops, fleet users, transport operators and machinery maintenance teams looking for a dependable 85W-140 GL-5 gear oil for hypoid axles, differentials, final drives, commercial vehicles and heavy-load gear applications.
